exhuast question
i have a 2 1/2 cat back straight threw muffler no back box its good nice crackle to it but if i change the pipe from my cat back to the manifold to a larger pipe without getting extractors will this increase the noise and crackle because more gases are getting out or will i lose power?
i think stock would be lucky to be 2 inch it seems small. ive only got the standard cat in there wouldnt this have to be changed if i went to bigger pipe??
cheers for the advice..
