my mate in work who has the exact same car as me has just got a cat back powerflow exhaust fitted for £160 which is a good price undoubtedly but what are peoples general opinion on these exhausts??
i had a powerflow backbox on my old escort and it was ok but that was just an escort so there was no way i was going to pay mega bucks for anything more expensive!
my work mate says it hasn't negatively effected performance and too be fair it certainly looks better than the stock exhaust!!
has anyone else ever fitted a powerflow system to a BMW??
