ive had two mongoose`s and im currently using a custom made blue flame exhaust, cant fault the mongoose at all, only thing is the downpipe is easily damaged if your car is low, with the blueflame i found it to be a much better fitting exhaust so ive had no problems with any damage.

my mechanic who fitted it said its the best fitting exhaust hes ever fitted and it sounds exactly the same as my previous mongoose`s which i suppose is obvious as the guys at blueflame used to make exhausts for mongoose.

you can sometimes find blueflame selling directly through ebay, the 2.5 inch with 4 inch slash cut tail pipe worked out at £210 delivered iirc.

you wont go wrong with either one mate !!!!.
