Hey all! After wanting a RS for the past 5-6 years, in a few months I'll finally have one (evil laugh)...

ok, here's the question: one of my mods is going to be a Spintech muffler (I have one on my curent car, love it).

I need to know the stock 2.5RS exhaust piping diameter, and if the inlet to the muffler is offset, or on the center of the muffler. And the outlet on the muffler is centered right?


thanks guys!

The diamter is 1 7/8" which is on the small side. Get something like a Stromung Catback, Radom Tech High FLow cat, and borla headers and open that beast up :) For about a grand, you'll have one snotty sounding subaru..

wow that's small; although I bet it's good for some torque down low in the rpm's.

I'm only going to do a catback system (it's going to be my 1st new car, and I don't want to take any chances of something breaking and subaru voiding a part of my drivetrain warentee cause of it)

I might get a scoobysport catback if they make them for new rs's..

anyway, thanks for the info!
