I don't believe that the SI has a 2.25 inch stock B pipe for a second. Id say that one is either 1.75 or 2.0 and the hx is the same.

gimme a sec theres one behind my wood pile i'll go measure for you...

Edit: 1.75 in...

The stock chrome tip is 2.25

lol, i was way off

do you guys think the b-pipe on the Si is the same as the hx? or would the hx be tiny?

Can't confirm...although I'd bet its the same. It's my understanding that the only thing that differs the Si exhaust from any other 96-00 Civic exhaust is the chrome tip ....If you're considering getting an "Si b-pipe" don't waste your time or money. Just get or save for a whole exhaust system. I have an APEX'i World Sport system and I love it...only 390 too

Edit: how about that cookie?

Im pretty sure that all 96-00 Civics use the exact same B pipe. Check hondaautomotiveparts.com for part numbers to be sure.

depends if you include jdm , ek9 pipe is huge compared to my u.k ek4 pipe (should be same diameter as u.s si). id take pics of 2 together if i had a camera.
