B & B exhaust Collector pipe, no muffler

[sscates]

Just took the following off of my 82SC (track car). I'm looking to put just a collector pipe, two into one. No cat, no muffler. I'm not having any luck finding such a thing and have searched here (that three word min is strange). And yes, the muffler is for sale once I find a solution for a collector pipe. Any ideas would be appreciated.
