304 stainless exhaust tubing
The product showed up wrapped inside box, polished(grained) well. Tight fit on the expanded slip joint and mandrel bends are good with no warping or kinks throughout. I have not welded anything to it yet to see quality of the materials structure but its definitely a visually satisfying kit.

Sounds like a muscle car
I put this muffler on a cammed 350 truck with 2.5" inlet pipes thru the muffler and 3" behind the tire in the stock location, this thing sounds like an old school muscle car. Fools people for thinking it has dual exhaust but saves money on exhaust work. Highly recommend for anybody wanting to run a single muffler on most of your modern trucks and can save big on exhaust work while getting that muscle car sound. Highly recommend!
