Dynomax sells them. I have the part numbers for 3" aluminized pipes. You can find them on Summit or even order it from a local parts store under the Walker brand name.

Dynomax Performance 53061 (Over Axle)

Dynomax Performance 54064 (Intermediate Pipe)

now when people say the diameter of the exhaust, they are talking about the OD of the piping right?


so a 3in td system is essentially less than 3 inches of flow right?

Why would you want a 2.5" intermediate pipe? That's smaller than stock. Go on Summit, select your car and you can look it up under exhaust.

I called Walker today and found out that they also own Tenneco which owns Dynomax - felt silly when it was the same person who answered the phone.

Anyway, here are the part numbers they gave me - 55282 for the stock diameter (2.75 inch) pipe which supposedly is a one piece part. To step up to 3 inch pipe, you're going to need both 53061 for the Dynomax 3 inch over axle pipe and 54064 for the intermediate pipe.

I called a few shops to see if they had the parts available locally and they all said it was a waste of money to go with the 3 inch pipe if my stock one 2.75 is fine. I guess that's their opinion since I'm just going with a Magnaflow muffler with the stock cats and manifold.
