Q: As I'm removing the rear muffler, what/how many mufflers should I use to make it quiet again, preferably quieter. (space constrained) http://www.performanceexhaust.com.au/~2320 http://www.performanceexhaust.com.au/p/15-LONG-X-2.5-DIAMETER-MILD-STEEL-UNIVERSAL-HOTDOG/HD15250P-P - 2x of the oval mufflers have the same internal volume as the existing twin muffler so would that produce the same sound output? - Or I could fit twice as many hot dogs. How many hot dogs would it take for equal silencing as one oval muffler?- Do these 2 types work the same or differently? I don't know the sciences of mufflers other than I want straight through unrestricted pipes, no baffles or 1" Varex chokers thank you. Current setup is venom 4" dump & Cat into Pacemaker twin 2.5". While it sounds nice I want it to go louder with some sort of bi-modal/valve setup as I leave home in the mornings while the family is still asleep. Plan is unbolt the rear section above the axle & go from there, running one pipe straight up under the tray and through the rear tailgate. The other one will go up and across just behind the diff then out the opposite side of the tray, both straight pipe. Trick is once they get up under the tray ill put a y-pipe & butterfly valve to a 2nd (& 4th) pipe running on the other side of the trays main beams which will be full of mufflers for silence. Ill be moving the reversing lights, get half size break/blinkers & re-route some wiring. Also try & go Quad 4" tips but may have to settle for Quad 3.5" Between toolbox-Beam I have 5" tight so 4" wide mufflers at a maximum. Link to comment Share on other sites More sharing options...
