well people dump out the fender wall the time. But then your just headers which is good for a race car but for my lower Hp number it would sound awful hence dumping out the quarter and shoving a muffler in there somewhereSorry, I thought someone was talking about dumping it out in front of the door. Which I thought was unique. And I may have gotten that totally wrong. Good thing I got new glasses. Going out by the rear quarter is no problem.
