Hi from Australia Guys,I have a new set of 450 mm oval Stainless Delkevics,very happy with the finish and build quality,they did take a bit of time to fit,to get everything lined up .First I tried them without the rear inserts,wow these things are loud!!!,far too loud to use on the street with any level of comfort.I then put in the supplied db killer inserts,and that brought the volume down to a more bearable level----just.
I emailed Delkevic Australia and they got back to me straight away with the option of some extra long db killer inserts of which I purchased for $90 Aus inc freight,I have just fitted these and I think they bring the noise down slightly?,but still not as much as I had hoped.
The pipes have transformed the way the bike rides,I have both Kev Mods,and a stage 3 Filter,on the highway my bike now hammers where before it wheezed up to 140KMH + and will cruise comfortably on 120 plus,whereas before you could feel it was being strangled by the intake and exhaust.
All in all I am very happy with the pipes,and for the price ,you cannot go wrong (but don't forget the earplugs!!!)i
