Ok guys, need a hand here...would look under the car, but a friend is borrowing my jack.

Im odering custom piping from Kteller8 (accordnglydone.com) in 2.5"

Im plan on getting the Comptech MIG welded header soon, so I figure I might as well pick up a cat as well..

now, It gives me a couple options. they are as follows. (it is a carsound cat btw.) Which options do I need. (I'm new to the Intergra world mind you

Flange (Im wondering If I can reuse my stock flanges...but I doubt it due to the increase in diameter.)

none
2-bolt
3-bolt


O2 bungs

Front
Back
Both

and lastly diameter, which I need 2.5 so that is established.

here is the link if that came out as blabber to j00 http://www.accordinglydone.com...id=70


Thanks or any assistance/Insight.

 

If you need to, you can take my 2.5" cat since my car wont be running for a couple of weeks. Let me know.

 

Thanks man, If I get in bind Ill let you know.

I wanted to talk to you about some Zeal coilvers through Modern, so look for an IM.
