If you're going to toss your CAT (good idea, by the way, it will make a huge improvement in your performance), then why not spend the money instead on a muffler that will bolt up directly to your turbo, like most aftermarket muffs do. There would be no need for a test pipe.

To me, the "test" pipe is an excuse to run without a CAT, and an easy way to put the CAT back on for yearly emissions testing. If that's the case for you, then buy a new CAT and a test pipe.
Mark H. 1987 930, GP White, Wevo shifter, Borla exhaust, stock everything else. The result of a massive Pelicanite good will fire recovery effort. Truely an open book, ready for the slippery slopes to modification.
