Flowmaster 17395 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 Extended Cab Short Bed

The media could not be loaded. Exhaust fit perfectly, and sounds very very very good. Clamps are cheaply made so dont over tighten or u will break it like I did. Had to get new clamp. Its sounds amazing, highly recommended

Easy to install with moderate skill level. Great flowmaster sound. Ships with 40 series muffler and is rated as "Aggressive" in sound level, which is very accurate. The rumble is noticeable at startup, moderate at idle and loud with heavy acceleration. Sound level could be annoying to some especially in stop and go traffic. My daily commute is mostly open road so no real issue for me. I also installed a Spectre cold air intake and the combination seems well suited. I would recommend this system. Installed on a 2005 Chevy Silverado, Extended cab, 5.3L Z71 4x4.

It sounds perfect not to loud believe it or not was a lil worried about that install was super easy took maybe 1 hour pulled factory exhaust off without cutting it anywhere but truck is leveled on 33's had to kinda squeeze exhaust pipe to slide muffler on was a lil out of round I love it if I could add a second I would lol

Looks good and cleans up the back of the truck. Lots of compliments on the side out design, not everyone is use to seeing that in front of the back wheel. It doesn't drone on the hwy but has a nice sound, not as loud as the duals it replaced and the sound is directed away from the drivers side to the left rear. I didn't want the loud drone that my duals had when driving at hwy speeds with cruise control on. Just monotonous and annoying, loud only sounds good ripping around in town but most people drive hwy cruising the majority of the time and you don't get that up and down thru the gears that makes loud pipes sound good. This is just right but probably not loud enuf for young guys in their 20's or 30s.

Some reviewers and description stated that this exhaust wasn't very loud, I beg to differ. When I took my stock exhaust off I started the truck to see how it would sound and compared it after the exhaust was on, sound was almost identical just quieter with the exhaust on.I had a d.o.s.s. exhaust on my previous truck with cherry bombs and like the look so I went with this setup after I saw the price decrease from 455 to 288. I think the fact that the pipes exit right past the cab make it sound a little louder from the cab but I'm not complaining lol.During installation, I snapped off both exhaust manifold bolts because they were seized on and would just not budge. Ended up buying some replacement nuts and bolts at HD and total installation time ended up being around 3 hrs.Amazon description said that this exhaust would not fit my 06 truck for some reason. The item description said it would so I went with it.

Perfect fit

Da un sonido muy salvaje

Only issue I had was the pipes were slightly egged and I had to work at getting them in the muffler, could have happened during shipping, IDK. The system mounted well, went into the factory hangers perfectly. Sounds really good, loud but not too loud. Doesn’t have any drone at highway speed, only loud when your gettin on it.
