I am interested in losing the massive heavy can on my wr450 04 model. I have seen a nice akropavich titanium can and link pipe bu wonder how hardy this will be off road. I have them on my Mille and find the metal very thin, they dent and mark easy. Anyone have any experience of them or similar items, are they much noisier than stock and how will it affect jetting?? Any tips well received. PS it is a UK spec bike, with the legal e marked down turned exhaust tip. I would like to add this to the new can!!
