    Yea it sounded nasty (the wrong kind) so i switched to a 40. I even had a Z06 resignator on it after the muffler to keep the raspyness down. sounded great until i got the headers.

    You will lose low end power. Look into URD O2 simulators.

    I think he means the 2 cylinder banks are separate from each other and never combine.

    I can read what he wrote- but there have been several folks who have tried and weren't pleased with the performance. It hurts the exhaust scavenging...So I'm curious what he did differently.

    Ah. I thought you were asking what he meant by true duals.

    Well...I guess I kind of am. There were a couple folks calling single inlet, dual outlet mufflers "true duals"..so I want to see if that is the case or if he found a fix for the scavenging loss.
