Re: Replacing my stock exhaust and headers??
You will need long tube headers with 1_3/4 primaries and at least a 4" exhaust but all that is easy. Building a true 500 hp motor will be the challenge you will need at least 210cc heads and a 6500 peak HP to crack that 500hp mark. Also pay attention to everything all the little details like deck height and perfect valve train geometry will come into play
