^^ ?? It depends on your priorities. All my opinion but....
I would not make an exhaust change as my 1st mod, especially if all I wanted was a tail tidy. While I like the sound of an aftermarket exhaust, (mine is stock but drilled out), I would start spending money on things that increase performance (not necessarily speed). For example, upgrading the front suspension with either R6 forks or Gold Valve Emulators will offer value back to you on every turn. I did mine after being coerced....I mean CONVINCED by my riding buddies and the change is AMAZING!. My next big spend will be an Ohlins rear shock to compliment the change in the front. And yes, after that I might look to an aftermarket exhaust, if I can justify the cost.
Till then, I use this tail tidy....

It is strong, looks good and comes from a reputable company. Previously, I had a less expensive tail tidy sold by a forum member and while it lasted a long time, it eventually cracked from vibration, destroyed my Hiper Lites and scratched up my swingarm during its exit.
Oh, and if you want a little cooler sound from the bike, do a search on how to drill out the stock exhaust. No comparison to the Scorpions, Two Bros, etc.... but better than the stock sound.
End of my opinion ......
