If you went through the challenge and trouble of building a 565hp engine, for the life of me I wouldn't know why you won't care the least about actual 'flow-numbers' of a muffler, and seemingly just about the noise-factor.
Hey, What's wrong with Dynomax Ultra Flow's, Hooker Aerochambers or Hooker Max Flow's??
From all the testing i have seen the Hooker Max Flow is one of the best flowing muffler out there.
I didn't ask for a race muffler suggestion as I just would have slapped the race bullets on it.
Keep in mind this is more of a street car. I cruise around with my 2 young kids so I'm looking for a compromise.
