    Ive got a riva exhaust for the old waveblaster that Im about to get a coating of HPC. But before I send it off, theres a leak in the large water jacket allowing water into the exhaust. I dont know much on how the two stroke exhaust works etc and just want to know if its normal. Any help would be great.
    Thanks

    Not the manifold end but the one around the start of the expansion chamber. If I block one of those pipes up and blow into the other I can feel and hear air escaping into the exhaust pipe its self.

    i would say thats normal, as far as i know those riva 'red' pipes are a wet pipe (like a B pipe) ....but they dont have adjustment screws like a B-pipe.
