I know the downpipe is 2.25", but is the rest of the system 2.5" or 2.25"?

....although I have some sort of odd-ball unit as mine has all the hangers like the 2.25" one but my pipes measure 2.5"....go figure.

My Borla/Neuspeed system uses 2.50 inch pipe but uses 2.25 in mufflers.

a 2.25" downpipe, from there it's 2.5" piping but 2.25" inlets and outlets on the mufflers? That's the Borla system, right?

So what's the difference between it and the Neuspeed system besides $125? What's the difference between the old style Neuspeed system and the "revised" one?

although my Borla, Borla is 2.25" throughout.

very happy camper here.

I checked yesterday as I we are testing a new cat/downpipe combo for a HIGH Hp kit.
