High Flow Cat

Subyrex03 · 09-19-2009, 02:27 PM

I'm thinking of putting in a high flow cat. Right now I have an Invidia V3 and Bosal catback on there. What would I need to do to get a cat back in the system?

new down pipe. Invidia manufactures a good V3 with divorced wastegate that I ran for a long time.

I want to keep the down pipe and just add a main cat if possible. I also like the V3.

You'd most likely need a new dp cuz of the size piping/flanges of your catback etc. I have txs bellmouth dp to high flow cat to txs midpipe to prodrive axleback and love it. Thats a full turboback and then you should get a tune, though I myself haven't yet and have been fine. You'll love it! Get a new high flow cat and 02 sensor, space it, and you shouldn't pop p0420's every now and then like I am lol

You roll into a muffler shop with a cat and say, "install this and shut your hole".
