If it actually was any louder i would take the exhaust off the car or just always avoid the car and drive the g/f's car. It's so loud you really need to be in the mood to drive her ! Luckily i'm always in the mood, except last sunday really hung over, could have done with a standard exhaust then
I think Adrian can vouch it is nowhere near loud enough
+1 They are a very nice bit of kit, but a bit loud for my daily commute
And dont let Adrian catch you putting the bungs in, he'll pull them out and throw them in the bin
I put my bung in last week, It made no difference to the noise at all
