I have a modified BPM divorced downpipe turbo-back exhaust for sale. It started life as a twister which was so ridiculously loud that it could not be run on the street. I had a local guy weld in a Stainless high flow cat, and an aluminized resonator into the midpipe. In order to fit them both in, we had to do away with the flange where the downpipe and midpipe meet. There is an o2 bung by the cat. The downpipe was originally ceramic coated, now it is mostly worn off and has surface rust. The twister rear "muffler" was cut off and replaced with a 6" magnaflow straight through muffler. (much quieter) We added a custom bracket to the end of the muffler which gets bolted to a stock hole in the rear rocker panel behind the bumper. I have run this on my car for over a year, and have taken it off and put it back on several times. It is only a two piece system now, but I install/remove it by myself with only a floor jack and stands. Makes good power, fairly loud but really intimidating sound.

$450 plus shipping. Or trade for new sti injectors

I also have original twister rear muffler and brand new thermal dynamics 5"x8" stainless rear muffler- will throw in both for same price.
