Dynomax ultraflows...has it all and is the number one choice in F.A.S.T. and PSMCDR for a reason....




Really...??? Thats telling right there.

Is this what the winners use? Dudek? all those 10 second guys?

But also, is there more to it? as in, perhaps with all that cam wizardry and exhaust limitations there might not be a need for the best flowing muffler out there? Probably not... seeing how much a 2.5" exhaust IS such a restriction on a 600+HP engine, but its still worth asking.



Yes, I've spoken to several of the front runners and that's the muffler they use.....and trust me, those guys exhaust (pun intended) EVERY avenue for increased performance possible. If there was another semi-stock appearing muffler that performed better, that's what they'd use.

The 2.5" exhaust is a restriction on the 800hp F.A.S.T. cars but the real restriction is the manifolds....which makes it even more important to use a low/no restriction muffler.
