After seeing the diagrams of the factory exhaust manifold and 4 cat setup, and reading what others were talking about, has anyone thought of doing a "race pipe" on the 6s? I know there's a full blown header system, but I'm sure there are plenty of people who want to be able to pass the tail pipe test.

Please have a look at the VQ35 Altima and Maxima for reference.

it would be a good idea. and we would still be able to pass the sniffer test if we just ran our pre-cats since our car is ULEV. just wouldn't be Ultra anymore but we would still pass. would prolly yield a couple HP/TQ. would cost more to develope and dyno than the actual unit would be worth in my opion. headers are the way my boy!

Bueller? Bueller?

I guess when I finally get my car, I'll drop the $$$ and see if Kooks Custom Headers can do something for me.
