Which Catco high-flow converter to buy?

[Cynic94rs]

I just paid a visit to Summit and I like the prices I'm seeing over the OEM one at www.cheapexhaust.com.

What part # do I want for my 94 RS... and just for curiosity's sake, what is the width of the stock 4-cyl exhaust piping?

i believe the stock exhaust is 1 7/8 not completeley positive though

catco sucks...unless you want to blow out all of the catalyst material after a hard run at the track, get a carsound (magnaflow). Proven and flow better anyways, & are cheaper.
