ANybody know where I can get a 180 thermostat? Anybody know what size pipe comes from that catylic converter im looking at purchasing a highflow cat from magnaflow, already have a flowmaster and cold air my original cat is all broken upo inside.

Thermostat? Parts store. Tell them what you have, and what you want.

Pipe? You'll have to measure it, unless you put some information in your signature so we know what trim level you have. Assuming it'* a 95?

Too little information.....

I have a 95 ssei, series 1, i was just wondering if anybody knows what the pipe diameter is on the catylic converter? does anybody have a high flow cat, or any other mods to there exhuast. I have 2.5" from the cat back with a flowmaster will i notice a difference if i remove the resonater?

I dont think removing the resonator will improve anything. But aint the width on the Supercharged models 2.5"......?

You'll regret removing the resonator. Trust me on that. The 92/93 models didn't have one, and I'm damn glad I installed one with my Magnaflow setup.

Diameter is 2.5". If you really want to do something with the resonator, Magnaflow sells a combination hi-flo Cat/Resonator unit.
