Exhaust size and design.
Sorry for the bad english, not my main language.
Setup.
400crank HP
longtube headers, 3 inch y-pipe at the "front". Going to a singel 3" ( no cat ) pipe. Then back to a 3 inch rear y-pipe and 2 preformance mufflers.
Is that enough? Or would I benefit alot to go true 3" dual all the way?
Thanks
Thanks


Steve
