Configuration constant with both: Maxspeed Headers & Sport Cats

Clip A: Stock Muffler

Clip B: Maxspeed Sport Muffler

The rasp is most noticeable on clip A. I've pretty much determined that the sound is coming from the sport cats. Clip B sounds better to me but I have cabin drone (not terrible though).

If I put the OEM ones back on I need to fight with getting the original O2 sensors off (they are frozen stuck).

Enjoy
