I just installed the Vibrant exhaust on my MSP and am passing along my opinion. The install was easy until we removed the nuts off the s pipe studs. Unfortunately, we broke two of them. After drilling them out and retapping the threads, everything went great. I did have a fitment issue with the muffler pressing against the rear bumper. We had to heat the hangars and bend them a little. I went to a friends garage so he had all the tools needed to install the system.
I run the exhaust without the silencer and it sounds very good. It has a deep grumble that is not raspy at all. It has some drone at freeway speeds but certainly tolerable. I would recommend this exhaust to anyone looking for a three inch performance system. My previous system was a three inch catback exhaust. I have not dyno'd my car, but the vibrant seemed to pull better with the j-pipe. It is very well made with nice welds and seams. I have not driven a car with the GHL turbo back exhaust, but for the price and sound, I would recommend the vibrant to anyone.
