Re: Cat Back
Thank you all but am curious, why two pipes at the end when the long center pipe is single ? The further from the head you get the cooler the gas so needs less flow area. I have an crossover ("H" pipe) on the Judge and remarkably smooths the pulses particularly on overrun with the glasspacks nearly six feet from the heads.
8s are special cases because of the interesting paths you need to make the pulsing even particularly with a wild cam (why the Ford Indy engine had the bundle of snakes but few V8s exhaust to the center.)
Sixes, particularly fairly mild ones are easy since their is no overlap but my understanding is that the Merc is a 90 degree V6. Buick had to use an offset crank to make the 3800 and particularly the L67 breathe properly. How is it done in the Crossfire ? Uneven length intake and exhaust only works for a narrow RPM band. YWTK.
