This is my second one of these mufflers. The first I put on a 500hp 6.0ls powered Tahoe with long tube headers no cats, a vibrant ultra quiet on each bank, then electric cutouts when I want it loud. After the cutouts it merges the dual 3” down pipes into a single 3” y pipe and leads straight to this muffler then out the back. In the truck with the cutouts closed it’s essentially quiet as stock, even at WOT the exhaust note is very quiet with this muffler and the dual vibrant ultra quiet’s and that’s what I wanted for towing long distances on the highway. This muffler has been in this Tahoe for close to 4 years now and still looks and sounds new, despite lots of 7,000rpm clutch dumps. The second of these mufflers I just recently bought and installed on my 1996 k2500 with a basically stock 5.7l small block. That truck has stock manifolds but no cats and dual 3” y pipe into a single 3” which leads to this muffler and out the back. Without having the dual resonators like my Tahoe has there is a distinct muscle car kind of idle note when you stand back at the exhaust exit. It’s almost like a low growl that lets you know there’s a nice healthy V8 under the hood. I side the truck it’s basically as quiet as stock maybe 1-2 decibels louder than stock but the ac blower motor is louder as is the engine noise itself. It’s exactly what I wanted with this truck because it tows a lot and I again didn’t want it screaming at me on the highway with a heavy load. To sum it up these mufflers are very quiet and if that’s what you’re looking for you’ve found it. I tried half a dozen other combos on my Tahoe and were disappointed every time with either drone or some weird note that drove me nuts. I will absolutely buy these again!

First one I ordered had a huge hole in the output pipe where the seem was welded, straight outta the box. Poor quality control. Returning and ordering a replacement as I still need this item. Walker customer support was useless so that's concerning. But no one else makes a quite Stainless exhaust.
