ive just seen a mk2 golf gti with a twin exhaust running under the car, he had cut 2 big holes in the boot floor the exhaust went inside the boot and then in through the rear panel where the number plate was he cut 2 more holes for 2 stainless backboxes i wish i had my camera, and i would have put a picture on ,when i first saw the car i expected there to be a big turboed engine but no it was standard gti ,as anyone else seen it wolverhampton area .
