I'm going to get a high flow cat welded in to my exhaust some time in the next couple of months. I have a full 3 inch turbo back. What do you guys recommend? Is there a "go to" high flow cat that won't hurt performance? Gonna get pro tuned after the cat install as that is the last power mod I'll be doing for a while unless I find a cheap tmic.
dude, i need to do the same thing. Please let me know if you find a good shop. I hate taking me exhaust off every year just to pass the emissions. >.<
