Hey there, sorry still learning this format of the forum. I didnt notice the notification; you can email me directly sales@kteller.com or aim mkteller8 or yahoo kteller8:

i have a few options based on your needs:
we can sell a testpipe that will connect to the Bishi header and then our exhaust;

I can sell you a high flow cat from carsound/magnaflow and have it bolt up ready;

last but not lease i can sell these in parts as a kit if you can install and weld them yourself; to save money.
