Thats what im saying you can get a high flow cat and exhaust for that amount. I was also looking into those N75 valves and seen a couple posts on other forums that were saying the aftermarket one isen't safe for your car and throws things out of whack. Do any of you guys have the race N75 valve? Do TT's just start going down hill once they hit around 50K miles? I don't think my clutch is that tight anymore. I looked into those a little and for a new upgraded clutch and flywheel there at like $900 buck + install. I guess if it goes wrong, you have a reason to upgrade ( looking at the brighter side of things)

 

I've heard changing (upgrading) the flywheel is a bad idea. Its a duel mass wheel, and you won't like the ride if you try a lightened one, and the vibration will eventually do bad things.
