Hey all! With all this talk about performance and the differences between PRV's and straight Volvo engines, as well as oil and what not, I have been spending quite a bit of time under the louvers to find some things out about the uniqueness of this car's powerplant. I am curious, and I know the veterans on the list have an answer, as to whether or not there is a really good exhaust upgrade kit. I am looking for something along the lines of the DMCH stage engine upgrades but unfortunately DMCH doesn't sell those systems separately, yet :D. We all know that one of the biggest problems the PRV has as far as performance is concerned is the extremely restrictive single exhaust system that it has. A muffler with two exhaust pipes means nothing if it only has a single exhaust intake from the engine that is bolted to a very large and restrictive catalytic converter. The ability to clear exhaust from the chambers quickly, greatly enhances performance. I read by sticking with the current muffler and just taking off the catalytic converter will boost power by about 15-20 HP. I hope this thread doesn't get as heated as some of the last ones. Remember we're all friends in the same boat...er car.
