Are there any GP style mufflers that are designed for other models that will fit on the stock 05-06 header?

M4 there you go

It is louder though, but they do have an insert out now that really quiets it down if it's too loud for you.

I have the exhaust in the picture above. There is a perforated triangular baffle that quiets it down quite a bit. It's a high quality exhaust (build quality is actually excellent). It isn't stupid loud, but people can hear you coming down the road if you are in it. It has a really deep drone that is soft except on downshifts where you get sharp pops and crackling noises.

I like the M4, but I'm not an M4 dealer. I have a piece of stainless steel that's slash cut on it now, so it can't possibly be louder than that. I was hoping one of the 650/750 setups might fit from Akrapovic or LeoVince or someone like that. Anyone want to sell me their M4 for cheap?

yosh r55 is another

They don't have the R55 for the 05-06 model.

I have the m4 as well..Love it...but if i was to get another gp exhaust, I would get a racefit....

The racefit is bigger than I like. Maybe you should go ahead and get yourself one, and I'll buy your M4.

Sounds like a deal in the works

Guess it doesn't matter now. I found out yesterday that my front wheel is bent way worse than I thought it was, so I have to get one of those first.

Damn...and i was actually thinking about it....OOHH well another year with my WONDERFUL EXHAUST :lol

Well, I'll be sure to let you know when I'm ready.

Anyone wanna do some kinda trade for a Ti scorpion slip on? I like my scorpion pipe and it sounds great but I wanna go back to a gp style one mainly for aesthetics
