View Full Version : Milltek exhaust advice

12-22-2010, 05:44 PM
I am trying to figure out what I should do with the resonated exhaust that I have. I am trying to figure out if I should turn my cat into a test pipe. Basically beat out the inside. I don't want a drone noise though. Will doing that give the car more horse power. How much louder will the cat make it or.... I don't know I have been watching ton of YouTube videos, but I just need some ones input to figure out what I am gonna do.

Gut your cat. I ahve a resonated Milltek as well, although I have custom straight piping all the way back to it. The milltek is subtle.

I have a Labree HFC with Resonated Milltek. One of my favorite mods.

The hollowed out stock cat has been known to have a really annoying sound to it vs a test pipe built by companies (though, I find those annoying also). I preferrably like things quiet and would go with a HFC. With the stock turbo, I doubt you will see any gains at all. With a larger turbo, you would more than likely see quicker spool times along with a nicer power band (more free flowing).
