1. What will I need to install a Legato Performance Exhaust system on my car or truck?

Legato Performance Exhaust systems come complete with everything you need to install the system on your vehicle including detailed instructions, tubing, mufflers and clamps. Our systems work with the factory hanger designs and will easily replace the stock system meaning you can install the complete system in your driveway using simple hand tools. In most cases, no cutting of the factory exhaust is required because the Legato kit connects to the factory exhaust where natural breaks occur. If no break is present, a hacksaw to cut the tubing and a metal file to dress any sharp edges should be used.

2. In addition to a better sounding exhaust note, what other benefits can I count on if I install a Legato Performance exhaust system?

Both our axle back and cat-back exhaust systems feature our unique muffler design that reduces engine backpressure and delivers our signature performance sound. Reducing backpressure also reduces engine-operating temperature while increasing engine efficiency. This ultimately generates slight increases in power, torque and mileage. While these increases are not huge, these are secondary benefits to the sound improvement. Its all topped off with a cool performance exhaust tip that says your vehicle is Legato exhaust-equipped.

3. My friend says that the mileage he experienced on his vehicle after installing a new performance exhaust initially dropped a bit but after about a two months he started to see a slight improvement in mileage. Can I expect the same from my Legato system?

It's a strange phenomenon but the quick answer is yes. Your friend’s experience is not uncommon. The fact is, since your vehicle will sound so much better with the Legato Exhaust, you will be dying to hear that cool sound – and as a result your driving style will be “less fuel conscious” for a time until you become used to the new normal. For the record, we don't advocate aggressive driving of any kind – even if it sounds great.

4. Will a performance exhaust system void my factory warranty?

No. The Magnuson-Moss Warranty Act of 1975 states that an auto dealer or manufacturer cannot void your warranty coverage if you have installed non-OE parts. That is true in all cases unless it is found that the non-OE modification caused or contributed to the failure or some other part or vehicle operation.

5. Will my Legato Performance exhaust system be covered by a warranty?

Legato Performance Exhaust systems are covered by a limited lifetime warranty to the original owner on the original vehicle of installation. In addition, proof of purchase is required. Legato Performance Exhaust systems are made of heavy wall tubing that wont rust through – you can bank on it!

6. I was told that all true stainless steel exhaust systems are magnetic and the amount of magnetic attraction is a way to determine the quality of the stainless. Is this accurate?

No, that is a myth. Everybody knows steel is magnetic. But what may not be commonly known is that stainless steel, for the most part, is not magnetic. Neither is aluminum. So touching a magnet to an exhaust system to determine what it is made of doesn't always tell the story. The magnetic properties of stainless steel are varied and have nothing to do with the quality, performance or durability of the exhaust system. With 400-series stainless, the amount of nickel contained in the material will directly determine its magnetic abilities. With 300-series stainless, there is virtually no magnetic attraction. Don’t let anyone tell you that all true stainless is magnetic – don't be misled. All Legato Performance Exhaust Systems are 100 percent stainless steel.

7. What is the difference between stainless steel and aluminized steel?

For years, the exhaust industry only offered systems made from aluminized steel, which was a great low cost way of transferring toxic exhaust gasses to the rear of the vehicle. But as cars and truck improved in quality, so did their exhaust systems. Today most vehicles come with a stainless steel exhaust – and most of the time it is 400-series stainless steel because it is durable, less prone to cracking over time from vibration and impacts that occur from road hazards. Rust through with aluminized steel can be a huge problem especially in climates where road salt comes on contact with the metal. With 400-series stainless, rust through is not a problem even though a light rust colored film will appear on the outside of the tubing and mufflers over time. Some high-end exhaust systems are offered in 304-series Stainless steel, which retains its silver covering longer than 409-series but is not idea for the main exhaust and muffler components. For that reason, we feel the best performing, most durable and overall best choice is 409-series Stainless steel for any performance exhaust system.

8. My exhaust tips have become dirty with exhaust soot. Can I use a chrome polish to clean them?

Yes, chrome polish will work but a stainless steel polish is actually much better. Your Legato exhaust tips are made from high grade, thick wall, polished 304 stainless steel and as such will need cleaning from time to time. Cleaning them regularly will avoid pitting that can come from long-term neglect. Stainless steel is far better than chrome, which can age and eventually peel off in this high heat environment. Use a micro-fiber towel and stainless steel polish to bring your stainless steel tips back to like new appearance. If your exhaust tip features a drain hole in the bottom of the tip just inside the lip, make sure it is not clogged or the condensation commonly found in exhaust systems will not drain correctly and leave a hard to remove water stain.

9. Will my vehicle be emissions legal after I install a cat-back exhaust? How about with an axle back exhaust?

Both Cat-Back and Axle Back exhaust systems are legal by federal standards as long as the catalytic converters and other emissions equipment are left intact. Legato Performance Exhaust systems work with all stock emissions components. On a few very rare occasions there are regional issues concerning aftermarket exhaust systems. A simple online search with regards to your area will note any unique local limitations with regards to aftermarket exhaust products - (amazingly enough, there are no such regulations in California, New York, New Jersey, or other highly populated states at this time).

10. How much is shipping?

Shipping is FREE to anywhere in the continental US. All orders are processed in 1-2 business days. Shipping is via Fedex Ground and will take about 2-5 business days depending on the distance.

11. Where are your exhausts made?

Our exhausts are designed, engineered and tested in the USA. We manufacture in China by an OEM specialist that has decades of experience to the highest quality.

2007-2013 Chevy Silverado 1500 & GMC Sierra 1500 Cat-Back - STAINLESS STEEL - Polished tips - Exhaust System

great exhaust system

very easy to install fit is perfect sounds great

Cat Back Exhaust

Instant gratification!!! This is thee exhaust system you want if you're looking for the muscle car sound.

Thanks for the awesome review!! We're so excited you love our product :)

Very nice quality and sound

2013 F150 5.0 4 door Supercab.
The exhaust system was a direct fit without having to cut any of the pipe supplied. Everything fit right together like you'd expect. You'll probably need to use an impact driver on the clamps. They need to be very tight to support the exhaust tips or that section will slip down. I hit it with my 1/2 impact and it's sturdy and staying put. No exhaust leaks. This is not loud at all and I'm glad. You can hear it through the RPM range while listening to the radio quietly but it's not loud enough to disturb the neighbors. At highway cruising speed, you can slightly hear it. It'll wake up if you step on it. Just what I wanted. Quiet enough while cruising but very audible while accelerating. Would prefer black tips but I can paint these.

Not as aggressive as the videos

Not the sound I was expecting.Not much louder than the stock exhaust. I’m going with a different exhaust system to get the sound I’m looking for.

Great quality for the price

The packaging for the expedition is bullet proof(and I like it), the quality of the parts is great and the instructions for the instalation are clear and easy to understand.

I have 2 points to note.
1: I don’t have the 3/8 bolts for the instalation of the truck exaust to the Legato Exaust.
2: I take 15-20 minutes to identify each part for installation. After that, it’s easy to install

For resume, great kit for the price. A little bit loud on highway cruise, but I like that!

I had it professionally installed in about 2 hours.
It was everything I expected.Gives my challenger a nice rumble without being to loud.The drone is minimal as a lot of the other reviews have stated.Im really happy with this exhaust kit

Added some Breathing Bass

Instructions were on point with the cuts at a good spot an install was good, Sounds a lot better with a deeper tone which I like, now with cam Headers an 2650 Its a lot of pressure breathing out those Legato's an holding well noe for 5 years strong! Great choice! Recommended for sure!

Nice exhaust

Nice system installation was easy seems to be good quality my only complaint is a slight drone right around the shift point on normal driving 1800 rpm’s


This is the easiest exhaust I have ever done. I cut the old exhaust off in 15 minutes, had the new one hung in 45 minutes. Awesome sound. Love it. Thank you

Human Error understandable but a Hassle…

In fact I’m not satisfied at all because its not the right system for my car.. my mechanic thinks it’s for a Charger… And I will be contacting Legato to resolve this Issue, and I hope Legato will reach out to me….

So far so good

Perfect. went on my FX4 with no problems. Just ha to get the right hangers and everything went as planned.


Sounds good and easy to install. Only complaint is the rear hanger on left side that you bolt to the frame is shaped like an L instead of a C so exhaust is not hanging correctly

Great value and quality build

The exhaust sounds comparable to flowmaster super 44, just a bit deeper. Notice an increase in performance and no drop in fuel economy. Overall I love the fit finish and sound! Would highly recommend this exhaust!


Sounds amazing fast shipping great price for a boot on system. Definitely but again for a newer truck in the future.

Sounds amazing

The pipes fit perfectly I put a y pipe in place of the muffler and I love the sound

Great price

One of few businesses that offers exactly what they advertise. Would recommend

Decent system

Checked the box to make sure everything was there. I checked the instructions and only had one page when there should have been a few. Had to use a file to file down burs where the slots were made on the muffler to get it to slide over the 3 inch pipe all the way. Tighten all the clamps by hand, but couldn't get the clamps on the muffler to seal. I had to keep repositioning the clamps and used an impact gun on very low setting to get a seal. Also on muffler, dont know if it was left there to help drain moisture, but on one of the 2.5 outlets there is a hole in one of the welds. Decent system for the price and I'm content with the quality of sound.


I am so pleased with this system. My car sounds so good and is running great. ALSO the precision and ease of install and the appearance are unrivaled, I feel like I got a super deal compared to any other system on the market. DM

In the dark.

Had factory axle backs installed at 1,200.00 when purchased in 2015, going to order these and they should fit right in ,about a half hour.

Very pleased with it not to loud but not to quite its perfect!

Good sound, everything included, great workout!

Pros: the kit is complete and the pipe and muffler are good quality. The tips are nice but do need additional buffing as mine were dingy from manufacturing and not fully polished. The sound is deep and throaty but not loud and i have heard no droning.
CONS: My kit did not come with the plastic shipping inserts and i did have some out of round pipe. The kit is straight forward if you know what your doing but if its your first time your on your own except for email assistance. The web site number no one answers and the phone number on the instructions that says technical support says it doesn't accept phone calls so not helpful and i was missing the first 5 steps so i tried these several times to make sure i didn't miss anything. The WORST part is those freaking clamps! They are the desirable style but you will need a dose of roids, your "man pants", and a team of mules to tighten them down. I am 6-1 220lbs using an 18" Snap-On 3/8" ratchet and it was ALL I could do to tighten most of them to the point where the pipes stopped slipping and secured. I actually snapped off one of the 3/8" metric equivalent bolts trying to lock down a joint and had to get another clamp. The only other issue and this is minor but kicked in my ocd is the last offset piece for both sides is a flat offset and needs to be an off axis offest as the tips on both sides kind of point down and cant be leveled straight. Both sides are this way and the tips are short so it doesn't look like a mistake just a different look. All in all this is a good all inclusive kit and DOES SOUND GOOD just be ready for a workout. Took me about 3 1/2 to 4 hours to do on my back in the driveway with no special tools.
