    Hmmmm

    I really wonder how well Port Matched the Divorced pipe Designes are..

    I remember when i had a R32 Golf..

    there were two sets of Exhaust headers available...

    Super sprint was one and Miltek the other.. both same price

    supersprint was exactly port matched... miltek had cheap round ports (not Square ports like on the head)

    Lazydog, that was the additional appeal of the CP-e pipe. It bolted onto the stock exhaust in minutes. Sounds good too, quiet but a muted purposeful rumble.

    BTW, I still have a 3" CP_e catback exhaust for sale, only 20-30kms on it, as new, back in the box, if anyone wants one.

What's better? that's up for discussion.
    Correct, no cat in TXS dump pipe. They run a highflow cat in place of a race pipe.

    CES utilizes spit DP as well.

    Not true, The TurboXS system will fit a stock catback. But unlike CPE and Cobb, the TXS, CES and pretty sure corksport run the dump pipe as a separate item from the race/cat pipe. Thus buying the two rather than one.

    Do you really need a cat for the o2 sensor to work well ? ? ? Cause my GTiR isnt running a cat, just turbo, dump pipe to rear muffler and it runs fine. If not even better since the cat was removed alot more punch in high revs

    No you don't.... All that happens is the 2nd o2 sensor will throw up an emission CEL for awhile.

    No cat.... enjoy the fine if/when you get caught

    Yeah i didnt think it did cause my car has always run fine, if not better since the cat was removed. .

    The rule is stupid cause older cars dont have to run cats
