Single chambers rule! I have those mufflers on my car too. Mine are 2 1/2". I think the part number is 325108. They sound incredible and aren't restrictive at all. There are only two other mufflers I would have on my car. I was stuck between the single chambers, sweet thunders, or the pro flow twisters. I'm glad I chose the single chambers.
