Won't get a prettier system than the GN1 duals, I run them on my GN and sell them on my site too. Surprisingly quiet. Had some minor fitment problems on my GN but it is very low and needed to take trim the pipes going over the rear axle to gain a little clearance. Normal height not an issue. I highly recommend using the optional band clamps I offer instead of the clamps normally included with the kit. Easier to make adjustments when installing with them and if you ever need to disassemble in the future you don't ruin the system like you would with traditional clamps.
No drone on my GN and actually lighter than the Hooker kit it replaced. Those Aerochamber mufflers are heavy.
