But that sharp bend around the differential just reflects the sound waves back through the exhaust.
With stock muffler - drone
Aftermarket muffler - drone
MF muffler in back cat delete - alot of drone
MF muffler moved to where cats where at and got ride of that sharp bend - no drone
It all sounds good if that was your intent, however you will have lost quite a bit of power moving the restriction of the muffler that close to your engine, I hope that won't bother you. The laws of physics are always right, some times we just don't interpret them correctly. That's why I did the CAT delete, with a "Y" in that place into a single 3" pipe straight to the muffler, deleting the resonator, and all the restrictions, the resonator and the severe bend in the pipe. The result is it sounds like a big V8 and I actually picked up some power.
