exhaust details needed...
hey guys does anyone know of any websites, books, or other references that go in-depth into the technical aspects of the exhaust system (headers, mid-pipe, and cat-back or turn downs)? this will be my next modification, but i wanna do it right. all i know now is i will have a GMMG cat-back. i was thinking of going with longtubes for headers and i'm not sure about the mid-pipe. but really what i'm getting at is this...
anyone can tell you to put anything on your car cuz they know it will work, but i also want to understand how and why. lol, i know kinda nerdy, but i take a strong interest in this stuff. however, any personal input would still be appreciated. thanks.
