I have not intended to cause trouble at all, if there is to be a comparison of any parts, exhaust or whatever it should be a valid comparison. Some folks parts may be sh1tcanned or praised incorrectly otherwise. 1olbull, plenty of folk were interested in ME spending time and effort testing air filters recently to see if they were what was claimed, so I guess the same applies to these exhausts. It is all interesting for the users of this site. Canberra, if done well the test will show that numbers are not meaningless. Maybe the absolute number does not matter, but the comparison number is very useful, thats how developement is done. With no development nothing would be available for any of you guys to buy for your bikes. Cheers guys.
