I'm definitely doing the mod where I cut a hole in my diffuser and want to add a duAl exhaust tip. The thing I have now is a little less than two inches in diameter and curves towards the ground. Do I have to cut the old tip or remove it or even replace the muffler all together? Also I'm not sure what diameter I want. Someone school me please
If you want growl and the slightest response gain get a new muffler. If you just want to add the tip see if it is welded on or screwed on. I never checked mine before chopping the muffler off for the HF muffler.
^^ Agreed. As far as diameter, it depends on what look you're going for. If you want nice/subtle quad tips, I'd say 3" (each tip), if you just want two big dual tips, then go larger of course. Good luck and don't forget the pics when it's all done.
If its the 4 door stock muffler, then just cut the end before the turn down and you can buy tips that screw on. Simple. But to dual it youll have to have a shop weld the other pipe somewhere, and in that case a new muffler with 2 outlets would be ideal.
