So I finally removed the head and wouldn't you know it my leak was from a cracked valve and maybe from bent valves (bent valves could have been ruined by me...). ANYWAYS, I looked at my up-pipe and noticed it had a cat on it. Well I was wondering should I remove it if I want more power? Also what are some quality up-pipes? I will probably research that stuff tonight but just wants to get some opinions. Thanks, Bnuts
Also, putting a catless uppipe in will not really net you any HP, it will (or should) allow the turbo to spool up a bit faster so you can get into the power a bit sooner. And remember, bigger is not better on the uppipe. Too big of a pipe and it will kill your spoolup. Russ
Swap in a used STI uppipe - they can be had quite cheap. For us LGT guys, the threat was cat converter material coming loose from the uppipe cat and the turbo ingesting it. Not a happy picture.
I was thinking about just getting a upipe that replaces the cat. Then just leave the exhaust. But we will see I change my mind often.
If you can install an up-pipe, you can gut an up pipe. Gut your stock one, take the bits and chunks to the scrap yard and get a few bucks.
I was also thinking that. I have a guy that comes around every once in awhile that pics that stuff up.
The local law enforcement loves it when you sit in your driveway pounding the catalyst materials out of your exhaust pipes with a 3 foot piece of electrical conduit and a 5lb sledge hammer.
