Looking forward to hearing your thoughts after you get more miles on the bike. I just installed my GP1 exhaust today. I already had a Rapidbike EVO and Sprint air filter on the bike. I haven’t taken it for a ride yet but I started the engine and I can say that it is definitely louder than the Arrow exhaust that was on the bike previously. It is borderline stupid loud now The quality of the exhaust exceeded my expectations. Here are some pics:I haven’t been able to get many miles on it yet, only about 60 or 70 but sounds great, in a very Paverotti vocal kind of way. It’s loud but not stupid kind of loud. A really nice deep bass...
The main thing for me was not only the sound but also the looks. Mine was a std Euro 4 so couldn’t wait to ditch the shotgun drain pipes.
I’ll get the Sprint air filter fitted this week and reset the RB Evo and then we’ll see.
