    Your best bet for a catted DP is probably helix. I only say that because it's probably the least expensive one you'll find and helix has developed a very good reputation for quality products...

    if you get a shorty DP like the Crucial DP you won't have to worry about the cat fix because it leaves your stock midpipe cat....

    I agree, forget about putting a cat in the DP....if anything (for emissions reasons), get a catless DP and have a high-flow cat installed between the DP and mid-pipe. Minimal (if any) performance loss this way.

    If you are keeping a cat, I'd suggest a shorty DP + stocker mid pipe. Another option would be the TXS stealthback. The hi-flow cat on the TXS system is in the 3rd cat stock location (visible under the car). Other full 3" catted DP's usually have the cat on the neck of the DP (not visible under the car). The only reason to keep a cat IMO is to reduce the smell and/or keep cops happy when they look under your car.

    I run the TXS and love it. Great for a stealth Stg2 setup IMO. You will need a CEL fix with the TXS unless you have EM.

    I've got the TXS downpipe with highflow cat like shwrx03 and I like it a lot. I've got their full TBE and it's great.

    The 4 inch downpipe is almost comically huge for the tiny stock turbo our cars have but it works great and there is minimal power loss with the cat in there.
