i had a longlife exhaust onmy peugeot GTI 6. after going there i promised id never go back!! for a mid sport zorst it was the loudest thing id ever heard. i have now a full bluflame zorst onmy RS with a decat and it looks and sounds awesome. my bro had a full mongoose with decat on his RS and it looked and sounded almost identical. you got a safe bet with mongoose and bluflame but i think the blu flame is slightly cheaper. from personal experience, dont bother with longlife.
