Hi, I have an exhaust system which is surplus to my requirements. The tips are about 2.5" ID. The brand of mufflers is Supercat Performance. I would like to sell as is for $150 . It is off my 2 seater TT and needs some repairs. Buyer must pick up. Thanks for your help. Regards, Steve Hayes Ph: (07) 3843 4422 or 0411 780 281.
