As Paul said, LPMM. No more power, just sounds much better. No backfiring. Similar in theory to OEM Motorsound muffler, except the by-pass pipe is on the outside of the muffler instead of inside. IIRC, the Motorsound internal by-pass is about 1" but, obviously, one can select any size external bypass, the most common is probably 2".
Add a Motorsound airbox cover (keep the stock paper filter) and it'll end up sounding like a Porsche.

Jimbo3, the Motorsound airbox cover was installed already with a K&N filter.
Just wishing in trying this mod, but i still think about the adjustable flap control to that mod pipes that i want to add too. (but still don't know where to start).

LPMM isn't much louder until you get on the accelerator. If you just want it to be a little louder, go with a 1 1/2" by-pass pipe.
