i have staintune from your part of the world, chose these as they stated no rejetting neccassary and they were right, but several months later i removed the air injection and actually had the carbs rejetted and boy what a difference, the pipes cost 511 gbp through an importer but with the performance gains well worth it in my opinion, worth the high cost over triumph tors which would have been half the cost but don't look as good sound as good or are expected to last half as long
