Now after riding my xt660r for a few weeks completely standard, I removed the airfilterbox snorkel and the bike rides more smootly.
The only thing I want so badly is a good exhaust on it because it is just to quiet for me.

Someone in my neighbourhood is selling a hashiru by polo exhaust for a xt660, but is this any good (sound, quality, does they have db-killers?)

Or the other possibility is that I can buy leovince x3 cans (from a ktm smc625, I think those are the same as for the xt660) and than buy laser pipes (from a xt660x) to connect the cans with the header pipes.
Why this combination? Well I do like the option with the leovince x3 cans that I can choose which db-killer suits me best.

Yes the second option is a little bit diy but I think it is good doable, what do you think is the best option?
Bare in mind I choose for seconds hand exhaust just because I dont have the money to spend on a new exhaust.
