I have a DRZ400 with a Muzzy Ti pipe and muffler sys. It is almost identical to my FSE450 with the FMF muffler. Surprisingly, the Muzzy has much larger pipes, probably puts out much more air than the GG sys and is much quieter to boot.
I'm working on trying to fit the Muzzy to the GG. I expect it will make my GG run better and also make it more quiet.
Yes, I'd like something quieter than the FMF but I'd also like not to loose any HP in the process.
