myeverlovinsir i meant exhaust head bolt. not the main head bolt.

but if i am wrong please correct me. i got that info long time ago when i post as spoon_ep3 if the spoon headers would fit on our ep3 and somebody replied no.

yeah the type s header will fit our engine, but it just doesn't bolt up correctly at the downpipe/cat

For instance when some ep3 owners bought a type s, the engine came with a stock type s header on it. But they had an aftermarket one and wanted to use that, plus, if they use the aftermarket one, it will bolt right up to the down pipe...so they just took the aftermarket one from the ep and through it on the type s motor so it bolted right up with no exhaust modifications

Sorry for jacking the thread...but I'm wondering...If I were to get a header...which one(s) will still bolt up to the cat? and not utilize a 02 sim thingy?
I'd like to...at some point in the far future...to have a header but want to maintain the cat even though it hurts performance and then I suppose a full catback exhaust?
I dunno if I'm just rambling...just trying to clarify some things because if I do mod my car...I want icebox, header, stock cat, exhaust... (full catback covers midpipe and axel back right?)

Okies...sowy...anybody know!?

so if SOMEHOW i can get myself a Type R EP3 cat, then we would have no problems with the b pipe connections due to the length of the pipe?

i dont trust o2 sims for the ep yet. the a3 has no mass air sensor, its all emissions driven, so alot of people with test pipes and o2 sims are having alot of motor problems

Here are the pics of my CTR spoon catback and USDM catbypass, and header.

This is the modifacation needed to use the CTR catback system

good deal IMPO, that is some good stuff, thanks for sharing, yeah so i talk to my mechanic today, and he says the b-pipe is not able to fit without a minor adjustment, so we proved that today... he recommended USDM si guys to get the DC5 header to avoid sway bar issue, and to fit a JDM EP3 type R cat is do able, but not good because you will not beable to pass emssions. This is under the circumstance that all parts are spoon parts and we are talking about legal street adjusted EP3, not track adjusted.

I have a Fujitsubo cat back, made for the CTR. I bought a used OEM exhaust manifold and a cat from an RSX Type-S for like $80. The entire exhaust system bolted together perfectly. If that helps anyone.
