My car is currently running the stock exhaust from the headers to the tips. Unfortunately there are holes in the muffler and intermediate pipe. Looks like I have a few options for the muffler assembly (racing beat, walker, bosal, Monza) but I haven't been able to find ANY intermediate pipes.

To those of you who have replaced parts/all of your exhaust, how did you resolve the gap between the muffler and cat?

 

Do you have to keep the cat?

 

I'd like to keep it, yes.

 

If you didn't have to keep the cats I would go with the RB StreetPort full exhaust setup which
includes, header, mid pipe with dual silencers and muffler. Sweet setup that will make that motor
sing.

 

I didn't think the RB setups had a mid-pipe, but requires you to use your own? If you can lose the cat, there's good gains to be had.

Though it's more expensive - I've had a lot of luck with two RB setups. They're long lasting quality parts.

 

Not true, the SP system replaces the whole package front to back but doesn't
include cats. You are referring to the early collect header exhaust system. Its little
less expensive but requires parts as you said.
