Flowmaster 17392 American Thunder Cat-Back Exhaust Kit 3 Inch Aluminized Steel 3 Inch Stainless Tips Compatible with 1999-2007 Classic Chevy Silverado GMC Sierra 1500 4.8L 5.3L Standard Cab Short Bed

I bought this exhaust thinking it would fit a crew cab. However, it did not. I had to take it to an exhaust shop and have them modify it to fit. The mid pipe was to short, they just extended it and had to relocate a hanger. This is the only kit I could find that would kick out in front of the tire, which was the look I wanted. After install I couldn't be happier with the exhaust it looks and sounds amazing. So if you would like to get this kit for a crew cab be prepared to have it fabed. The fab cost me $181.00 and i paid $346.00 for the exhaust so it came out to be a little more than i wanted to spend but worth every penny. The 40 series muffler sounds phenomenal!!

This does not fit Ext Cab 6.5' Bed Trucks! Had to bring it in and professionally Installed. Better off at an Exhaust shop all together!

I couldn't be happier with purchasing this product.. it shipped fast, had all the necessary hardware, and i saved plenty of money buying it here over any other site. The hardest part of installation was removing the old exhaust, but once removed this fit right in place with the factory hangers and bolted right on! Cool look and has a great sound.. it is somewhat loud in the cabin while driving but it really depends on how you drive..with music playing it blocks out most of the sound. What im trying to say is you can definantly hear it, but its not loud to the point where you'll get a headache everytime you drive. As long as you make sure it will fit your truck, this should match up with the factory hangers and exhaust flange.

this is an easy install and sound. the hardest part about the install was getting the old nuts loose on the old pipe

Great quality kit, was a snap to install and made a noticeable HP gain in the mid to upper RPMs. Audible level increased inside the cab, but not too much... it's actually right about in-between soft and too loud! I would recommend this kit anyone looking to increase the performance and sound of their truck!

Nice one

This product is worth every penny !1999 Chevy Silverado Z71 Shorty regular Cab only.It fits on Y-Pipe cat back.I had a local shop install it, as well as O2 sensors post cats.The sound at idle is nice, little louder than stock. After you put it in drive and excellerat through the first few gears you'll notice the loud Flowmaster rumble that is unleashed from your engine. I've owned the truck since day one and I can tell you I wish I would of installed it sooner !!!All in All great product

Easy to install, my friend has a lift in his garage. Sound is great not too loud, would recommend.

Installs don’t get any easier than this.
