I'm going from a very loud stock pipe on my '03 to the Q4. Should I expect to have to rejet?

Stock silencer with the baffle in or out?

baffle out.

You probably won't have to rejet. You might have to adjust the fuel screw. They are very similar mufflers, you won't do any damage if you run the Q4. Just listen to the bike and make sure it isn't pinging or anything.

Install it yesterday. Ran it today. About a turn and a half on the fuel screw and was good. Thanks wondermuscle.

how does the bike feel with the Q4? does it change the torque down low at all or help with the plugged up feeling at high rpm?

how does it sound compared to the stock muffler?

thanks,

Mike

Well, mine was stock but gutted by the previous owner. It was very loud and sounded metallic- raspy. I felt like i should be wearing earplugs.

My initial reaction to the Q4 was that my bike was slow. Loud is fast right?

I really like the sound. It is deep and throaty. I swear it feels like the bike lost some midrange and maybe a little bit of response. Maybe I need to adjust it back a bit leaner.

For the type of riding i do (woods), it's perfect. The bike makes a lot more power than I need, the pipe sounds good, is not offensive, fits perfectly, and looks decent.
