I ran a sano pipe and ive ran other pipes also i like the sano pipe never had any problems with it the other pipes ive used always semmed to come loose for some reason but the sano pipe stays tight and runs good on my bike but this is just my opinion i think if possible its a good idea to check out a few different ones to find the one u like best. I even switched with a friend for a couple days to see how his ran.
I have a sano exhaust and two bros pipe. I've ridden it about 1 hour and it's too noisy for my area. The exhaust is black and nothing is wrong with it. The pipe/exhaust was 250 new i'll sell it for 200 plus shipping obo let me know and I can supply you with pictures.
