Lately scrutineers are starting to be very picky about this. The JP pipes don't carry EFRA homologation number, so they are illegal for being used, this along the fact we need to use 3 chamber pipes makes the correct choose very hard.
I'll give a try to a Ninja 2053 (maybe has too much high end that pipe) I have here, but looking other possibilities.
Nitro$junkie: YGPM. Sorry for not answering before, hadn't caught in the fact I had PM awaiting.
