FMF Q4 Exhaust vs Yoshimura Rs2 Full Exhaust?

[GarveyTheGOAT]

Which is best bang for buck? What are the decible levels for each, with and without inserts? What are the performance gains for each? As I use my bike for commuting purposes?

Either or. They are low to mid-range focused pipes. Both are louder than stock but nothing compared to the average fluffer on a hog.

I have a full FMF. The fitment isn't the best, Yosh would be better. But I got it for a steal so I can't complain.

Performance will be the same with both. The FMF Q4 makes less noise but both sound nice. I have an old RS2 and the fit and finish is great.

I dunno, I've got the MRD and it's hella loud, I think prolly to loud. But I love it at the same time.   For riding up in the mountains and trails I wish it was quieter. I wonder if there is a slip on I could buy which would fit right on quiet it down a bit and not mess with the jetting? With the MRD...in traffic ppl hear ya coming and that's a plus.

Q4 with the powerbomb header was my choice , jetted to it and 14,000 km later Im still happy with it.
