Which is better for a stock 5sfe, 2.25 or 2.5in pipe? I've searched around and its a pretty even split on opinions between them. I've decided on the HKS Carbon TI muffler with the 60mm (just over 2.25 in) inlet, i know its expensive for a stock motor but it looks damn good and sounds sweet, my mind is made up. Carbon fiber is just so sweet!!!! biggrin.gif

Now i just gotta decide what size piping, its gonna be catback, and whether or not to go under axle or over. What are the pros and cons of each??? If i go "under axle" will there be any clearance issues since my car is lowered???

i know this question comes up a few times, but im looking for a definative answer...i've searched alot and i still can't come up with a good answer.

I would go 2 1/4"... honestly cat-back doesn't do very much to begin with.. and either under or over axle.. I doubt you will see (much of) a difference.

You should not have any clearance issues with under axle.

Some people here are running 3" under axle.. I don't know what their suspension mods are though.

Personally I'm running 3" turbo-back over axle.. even 3" is too large for probably 75% of 3sgte's. Since you are running a stock motor I would go with probably 2 1/4".. Just because any bends a muffler shop does will end up crushing the pipe down a bit..
