aftermarket hedder off a 93-99 cbr 900rr, i havo no info about this item it came with my bike. the pipe was fram a kawi or yami and was custom made to fit but ended up breaking off, i replaced it with a stock pipe and would trade for a stock/aftermarket slip on for my bike. i liked how the hedder stopped under the bike, i had a muffler tip facing downwards on the end for a while but it was tooo LOUD!!! for my taste. price is make me an offer/trade
