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'll just talk from my experience. I got 2.25 over the axle on my 5sfe, and I'm glad I went with that. You might not notice a big gain unless you get everything else running smoothly. Once I did, the 2.25 was great, I wouldn't have went with any other size. As far as the axle over or under, it all depends on the welder. I've got a guy that does great work, so I had him go over it and it's still really strait and free flowing. Have fun in your 5sfe, it's better than 90% of the ignorant people on this site think they are.
