Does anyone know if the actual length of a JDM SS ITR 4-1 is similar or far off from a header from a 99-00 Civic Si...?

predicament: 96ek/97gsr swap... right now im using a 99-00 Si header on my gsr motor... it bolts right up... and has the o2 bung right on the header... its great cuz my thermal exhaust included a straight pipe with it.... so everything fits perfect.

i bought a new RSR header for a GSR... GSR header is too short.. and doesnt have a o2 bung.... too much hassle...so im selling it to buy either a 99-00 Si header... or a JDM 4-1.

id rather have a ITR 4-1... so im wondering if its the same length? collector size isnt an issue right now.. im just worried about length.. .thanx for any help.

anyone know if a muffler shop can flare a 2.25 inch staight pipe to 2.5 flare?

 

They should be able to rig up something.

I had a muffler shop modify my stock CX catback to bolt to a Toda header.

 

Okay, that is one of the most counter-productive things I've ever heard

 

It's all about the midrange!

 

Just get a new longer testpipe with an o2 bung on it. It would be the same as a 94-95 cat. Then you can use the rsr header.

I was also interested in the rsr header. What is the collector diameter on it? Does the quality look nice? If you are selling the rsr header how much are you asking?

the jdm header has the o2 bung on it but i'm not sure of the length

RSR has standard US collector size.. but it looks really great...
i have a GSR cat in my garage.. and its the same size as my testpipe which is tooo short...thanx anyways

 

Its the same as the OBD-1 94-95 gsr cat, like I said above
