What exhaust ??

[Graham53]

Thanks guys , it gives me a few more ideas I like the idea of the Akra but not sure I've got Akra money , I've done some you tubing and I'm leaning towards the scorpion it sounds ok with the killer in and not too noisy out unless I can find an Akra at reasonable money , I'm unsure about the delkevic as heard some not impressed stories.
im not in a great rush so if anyone else has experiences/knowledge of cans I'd appreciate the feedback
