What's the best one to get? I've been looking at the Milltek, is that a good one?
Those are good, just about anything but a RISS or other cheap EBAY one as they may cause you headaches trying to fit. I highly recommend getting it ceramic coated , will keep the heat in and rust off, I paid a local shop $40 to ceramic mine, don't pay some manf the 100-200 more I see them asking for it, it don't cost that much.

Do I need to get anything else (O2 elims?) Need something unless you like P0420 cat insuff check engine lights. But my manic tune takes care of that.


What do I need to do about a tune? Am I better off getting a dyno-tune from a local tuner or getting a programmable tuner? If a programmable tuner, which is the best one? I don't want to have any CEL.
You can't buy any programmable kits like they make for chevy's etc, so you need to get a tune from manic or somebody like that.


I'm in the Chicago burbs if anyone has recommendations for a local tuner. I'm mostly looking to do this to add more sound, how loud will this be with the factory JCW catback? I like a lot of sound, so my concern is that it won't be loud enough for me.

And you guys still have OBD emission checks so you will have to put your cat back on for inspection.

Any help is much appreciated, thanks!
