Don't know if this is the right section for this Q but i will ask and if it needs to be moved so be it. I was wondering after you build a set of headers and you have your lengh on the collectors how far back do you place mufflers to gain optimal performance. I believe the farther back you place them the quieter they become but when you dump them out the side on a short wheelbase car there's not too many options. I didn't know if there was a ballpark figure or not. Thanks in advance for any replies.
