Why do you want to remove them? Monolith catalysts are NOT as restrictive as most people think. They generally flow as well as a good turbomuffler. Removing them will make virtually no noticable power. Some people hollow them out... BAD CHOICE. The empty "can" flows worse due to turbulence and creates NOISE.

I am assuming you want more power. Start by just removing the final mufflers as I show in my exhaust threads. The 95 has an identical exhaust system to my 99.

Follow my threads on exhaust in general. You will notice that I intend to upgrade everything from the catalysts back but I am going to KEEP my catalysts. Go to my profile, do a search for all my posts in the top right corner of that page and you will get a lot of exhaust information. Ask me in this forum if you want more specifics.

Hey poorman_nicelex!

I don't think there's any part to lower a/s. You would have to replace all four with performance shocks/springs.

I would leave the exaust system alone.First the car is designed to have it.Second more and more states are makeing it a rule to have regular emission test.My peoples republic of a state does that.You would be in deep do -do if you changed the exaust here.Carpe diem.
