Our new FlowFX cat-back exhaust system is manufactured using durable 409 stainless steel throughout and features a 3. 00 inch inlet pipe leading to a single inlet/dual outlet FlowFX "straight-through" muffler for great sound and maximum performance. The dual 2. 50 inch mandrel-bent tailpipes exit out the side at an angle behind the rear wheels directing exhaust away from your boat or travel trailer when towing. The system is finished off with a pair of large 4. 50 inch diameter black ceramic coated 304S stainless steel tips, giving your truck a custom look that goes hand in hand with that deep performance FlowFX sound. The system uses all the existing factory hanger locations and includes an additional hanger to install the new left side tailpipe. Includes installation instructions and all necessary hardware for an easy installation that you can do at home. Notes: Fits 2wd and 4wd models and 2019 Classic models.

Everything fit as it should. Install went extremely well.Only complaint is that the black paint on the tips is pealing off after a couple months. And now it’s almost completely off and looks like crap.

Was a fairly simple install. Everything fit just like it was factory installed. The sound is excellent. I didn't want a loud exhaust just a rumble. The magnaflow is perfect. Great product

I loved everything about this product! packaged very well and protected! Amazing color picture installation directions, fantastic looking quality parts, simple to install. and looks exactly like the picture of the truck in its sales add. Sounds fantastic looks amazing! couldn't be happier with this product!as far as sound goes, it sounds super aggressive compared to stock. loud when your getting on it a nice quiet not annoying rumble at cruising speed, but oh boy you stomp the pedal and she wakes right up!I'm really really happy with the quality that flowmaster has put into their products.

Super easy to install, one piece was broken so I had to weld it now it is very secure and performance is bada$$.

Very easy to install. Had to get a new car to pipe clamp. And the tail pieces are very fragile. Had to weld mine on. Clamps broke the outer shell and they wouldn’t replace. Just a heads up

Relatively easy to install, dealer wanted $1600 for the same set up. Was able to access everything with putting my truck on ramps. Truck has awesome sound and look forward to taking advantage of the extra horsepower.

Install on 2015 Chevy Silverado 1500 Crew Cab with 6” lift was fairly simple. Only needed a couple of tools to hang. The downside is the removal of the stock exhaust, which required a reciprocating saw (sawzall). The sound is fantastic, mean rumble upon start, and medium-aggressive tone on acceleration. No noticeable cab drone. Also installed a K&N air filter, saw about 30 mile per tank increase. Well worth the money, looks cool, sounds great.

Easy install, sounds ok, improved the look look of the truck.Doesnt give the great sound I hoped for, but after some research that's typical of the gm make trucks. My 2014 ram sounded amazing after just a simple flowmaster muffler on the stock exhaust system. Apparently I can't get a similar sound on the gm makes.
