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?

I have a 95 ST just like you, I have a header (corolla one) and my sticker is up at the end of the month. I have my stock manifold and b pipe that I am going to put back on for my inspection, then after it passes, swap the header back on. It really isn't hard to do and the header will make your ST more fun to drive.
