DynomaxSuper Turbo 17629 Exhaust Muffler

Sounds so much better than the stock muffler. Not to loud either.

Arrived on time, but the product itself was wrong, it was stamped correctly and even boxed correctly but there were no flow deflectors from what we can figure out the inside of this muffler is actually the walker quiet design. Amazon took it back with no issues so no problem just going to try another brand

As others have stated Dynomax has tried to pull a fast on on the consumer by subbing out something completely different than what they advertise (even on the box it comes it). No flow deflector, in its place there is just a "bump" in the case. Instead of the air being redirected smoothly 180 degrees it now hits a wall, then 2" over theres an indent. The tubes themselves are advertised as "large internal diameter tubes improve flow". Well for the 2.5" inlet/outlet it necks down several times, all the way down to 1.9". Its also not even a true turbo muffler because the 3 tubes dont run the entire length of the muffler, on one end it stops and hits a wall about halfway then is redirected. As for the "Fiberglass matting technology" a single pieces of extremely thin fiberglass tape, maybe 4"x4" in the center of the muffler is all there is. I dont know if dynomax could no longer produce these the way they advertised and shoehorned in some other failed design in its place hoping nobody would actually look inside but the deception is definitely intentional. Sad to see.

Great sound, deep grumble not obnoxious like most competitors

Muffler not as advertised. It's Aluminized, not Stainless.
