Update new gaskets on carb fires up and runs nice of course now because car is running properly have noticed a small blow/leak in back box so was thinking i can go and get a back box for about £50 or spend £180 plus VAT and get a all new stainless steel exhaust what you guys think bear in mind i only paid £500 for the car and so far have probably spend about another £400 with brakes calipers discs etc.thanks for looking
