I need a recommendation for a small and quiet muffler for a Jeep 2.5L. Currently has a small round Dynomax muffler and it is ridiculously loud...as in very annoying...as in my Jeep sounds like the "white trash express". The room I have is limited as the muffler has to fit between the bottom of the tub and skid pan, which is about 5.5" of room. The exhaust dumps out at the end of the skid pan, thus keeping most of the exhaust out of the way. What ideas / thoughts do you guys have?
