Aprilia Shiver 900 OEM Akrapovic Exhaust end can slip-on 

Sounds like a dream

Original Aprillia ones are this way, if you get them from another online shop, then they are the expected way around..

Did you have your bike remapped after you installed the exhaust? If so did you notice on your speedometer display if it says Aprilia racing or something along those lines? Secondly, I’m just noticing if you noticed any difference in acceleration after you put the exhaust on? It looks awesome!! Cheers 0:03
