Stock up, Cobb catted dp, Perrin 3" CBE.

 

But the question is: why do I have a 3" exhaust from the dp back if Cobb is going to pinch it off to 2" where it mates? I know it's for the donut flange on the stock but it's restricted an inch over what my catback is...sigh. I think Cobb needs to put one out that's 3" straight back.

That is why I am waiting for the iON TBE that is 3 inches all the way till Y-pipe.
