Is there a difference in fit between the 1-3/4" and the 1-3/8" (if those ar, which one would be better for my car? I think the larger ones would be best! Let me know.
Would I want to get them coated, or would it not matter because they are stainless steel?

Also is there anywhere cheaper than summit to get a Catco cat? Or is there a better cat than Catco?
Thanks,
Joe

well, for your 350, you'd probably want the 1-3/4", the other option has 1-5/8" primaries. as for coating them, since they're stainless, you don't need to coat them, but it would keep your underhood temps down with coating. as for fit, i've heard of some contact problems with the steering.
