What Size or Model?

[Jman]

Hey I'm putting on a new muffler on my Turbo mt, most likely a magnaflow cause there relitivly cheap and sound nice, anyhow what sizes/models are you useing?

[tris91ricer]

muffler inlet depends on the size of your exhaust, which should be 2.25".
I think most would recommend the 40 series when it comes to supercat/magnaflow.

Acctually mabee some exhaust work has been done on my car i measuerd with some calipers today and it cam to 2.5" exhaustbut anyhow i still need a new muffler cause mines almost rusted out!

Is that measurement ID or OD though? If you measured the outside (OD/ or outside diameter) of the exhaust pipe then it will be bigger then the inside (ID/ inside diameter) which is what we're talking about. A 2.25" exhaust (ID)would probably have an OD of around 2.5".

Yea, stock = 2.25" ID.
