Alright, thanks to a big *** speed bump, and my r being a lil close to the ground i Fd up my cheap *** DC 4-1, im am picking up a JDM header this weekend, anybody know the part number, or which carsound cat will work with the JDM header, and the JDM mugen TL? I will still need a 2.5 collector flange right? any help please...

 

Contact SMSP. He can get you a cat that's the proper length with the flanges and necessary O2 bung already installed, ready to bolt right on.

 

agree with Padawan. Dave Stadilus (SMSP) does great work, just tell him what your setup will be and he'll make it right.

 

OE jdmm heaer and jdm cat for me and not a single problem.
The only problem you might have is finding a jdm cat
SMSP= highly recommended.

 

what cat-back system do you have?
reason, the length of the cat might cause problems.

 

i have the JDM version, with the longer B-pipe..

 

yeah i thought about getting a jdm cat, but i would rather just get a brand new one, so i thought i would get the car sound.
