Well, after I started the car I was waiting for the sound. Hmmmm is that my car? Sounds like a luxury car now! haha Yeah, I've been so used to driving around with loud ass drone that I forgot what my car sounds like stock. Well, with the full P&L exhaust (minus catback), my car sounds stock. Now on the highways I can cruise at 70mph without ear plugs. I can actually hear my music. No drone at all. I can also get on it without drawing any attention to anyone that is 4 blocks away.
The only thing I hate now is that lovely sound at wot is gone and the tiny tail pipes that are sucked into the bumper. I am now in incognito mode! I kinda like it, but I wouldn't mind something with a hair more grunt, but less drone. I thought maybe Perrin. Anyone have any experience with the Isis catback? I'm looking for more flow but quiet. I think the Isis did better than the resonated Perrin in certain dyno's (DSport mag test) and was quiet as well.
Does the stock catback restrict flow that much? I thought about keeping it and just adding some tips for the visual effect for the rear end.

Wow, this is really helpful, thanks! We were contemplating switching the exhaust from Perrin back to stock and leaving P&L parts in place...now I know we should try that. Too quiet is better than too loud for me, and I already have good-lookin' Perrin tips on my stock muffler.
