Tried a GPR exhaust?

Anyone try a GPR exhaust on their SD? Howd it sound/ perform?

I think I saw a spot on U-Tube,,,,,,,,,,,,,,,,,TBH ,liking me Yoshi's,,,exept,,,would like em more if they were louder

I had one on my previous bike an Aprilia RSV mille.
I liked it, the quality was very good, looks are great and it sounded really awsome... Made the windows rattle when I started it.

I was tempted to go for them till I found the Mivv's.

I have a set on my 06.
When I finish putting it back together over the next few days I will be able to hear them for the first time....
I notice the baffles are able to be removed but I will give them a try with them in first.
Will let you know when I find out.
Im a cop here in NZ but loud bikes rule.....

Happy days
