It's called a Stinger exhaust by Weltmeister. It is stainless and rediculously priced at $989 in a catalog parts seller we all know. I have never seen it in Pelican's catalog although i'm sure he could get it. It has a nifty mounting bracket but otherwise could be duplicated much cheaper in stainless and much, much cheaper in mild steel.
I am wondering how it flows and if having the exhaust merge at the end serves the same purpose as having a crossover. I thought i remembered seeing someones car here with one like it.
