I might have just the thing for you. In the next few weekends, Im rebuilding my brothers RA28 and he is getting rid of alot of stuff which could include a full exhaust with extractors. Not sure on cat but its bloody loud and sounds great. I will let you know further
The extractors are off a 18RGEU. They are still attached at the moment. He has 2 cars both with 18RG's so the exhaust is gonna go off 1 of them and will prob be sold. 1 of them has a 5 inch stainless dump pipe and im not sure on the other. Basically 1 car is parts for the other then everything left over is going. I will ask him about it tonight. What you willing to offer???
