Hi there, I am in the market for a shorty slip on muffler, preferably reverse cone and preferably one I can tune. I do want something about 12 to 14 inches long (hey - don't we all?) and in black or chrome. It is for a Honda CB750 I am turning into a cafe racer in the 'modern' style. I have looked at SuperTrapp as one option - any other ideas or sources I could try?
