Are there any true 2.5" Exhaust systems? Ones that don't taper down to 2" or 2.25" inches??? If not, do you think that there is a noticable difference between 2.5" and 2.25" piping on an normally asperated H22? Thanks for all replies.

I would certainly think that 2 1/4" would flow more than enough for an H22a N/A.

all 2.5 in exhaust are 2.5 all the way back. 2.5 is better than 2.25

Why not get a custom one made at an exhaust shop?

I don't know of any in the Boston, MA area that mandrel bend, but then again, i haven't really looked too hard either.

2.25 is too small in my opinion, h22s love big pipes, get the 2.5......

check out kteller.com for 2.5 exhaust kits....

T1R is 63mm outer diameter from the header collecter to the muffler (its approximately 2.38 in. inner diameter).

I placed a preorder with R&D Motorsports ( http://www.randdmotorsports.com )

http://www.aj-racing.com has pics.

The header, race cat, and exhaust should be released late January.
