				Hey i was just wondering if i were to remove the catalytic converter if it would add any horse power? or what about getting a "Y" pipe before the cat. so i can still have the cat. but have it go straight out when i want to race?

				You are the only person I know who has said it makes no difference, mind you I only know people with turbo's that have changed them and on turbo's it makes a huuuuuuuge difference. It should increase your top end though. Nathan -------------------- 1994 JDM ST205 WRC with 17" OZ Chrono's wearing 215/45/17 Eagle F1's.
