As i said earlier,i've run into a wall with trying to get an aftermarket exhaust.
Akrapovic make a GS Race System with "Shotgun Silencers". Big Simp has/had one on his Moto'd GS,looks the biz but i want a single silencer.I cannot get just the headers from the UK Importers.HPN in Germany list a Full System for HP2/GS12 @ 2100 Euros
but won't answer my e-mails about buying one. BMW Mottorad deny the existence of the Evo System and don't list any aftermaket Non Cat Headers.I've run this situation past several folk who are "in the know" and keep getting told that GS systems won't fit,mounting points different etc etc.Out of curiosity,i've bought a BOS system,from a UKGSer (NOT the one who is leaving/staying/having a clear-out). I reckon the system will fit so next Monday i'm off in a van,with the bike and BOS system.
Plan A
1/Dyno Run with Std System
2/Replace Std System with BOS System
3/Dyno Run with BOS System with Baffle in
4/Dyno Run with BOS System with Baffle out
If it all goes T%ts up at Step 2,i have not,as yet,formulated Plan B though Wunderlich list a set of Non Cat Headers so, , , , , , ,
