My dealer tried to sell me a bike [orange] too slow with a set of roadhouse pipes on it and it was new. I bought a fast one [yellow] with the stock pipes. I now have a raw shorty and can put the stocker back on if I need to. Look in the manual It says it is illeagle to modify the parts that effect sound levels. My guess is it will depend on your dealer and what goes wrong.

The only reason I ask is that I got a 4 year warranty and if it is going to void that then im not doing it. It cost a chunk of change to get it. Thanks for the reply.

De-baffle exhaust

Thanks..... I purchased my M109 a week ago and I'm so glad there is a webpage like this, doing the debaffle of my bike was so easy following the steps you all log here. I'll keep checking the "How to, step by step" board to see what else I can do to my M109R....

Once again ... Thank you ALL..!!!

Has anyone experienced problems getting their Nine passed during vehicle inspections (realizing inspections vary from state to state)?

Drilled out the 2 baffles, tested it. Wanted it a little louder so I drilled 4 1/2" holes in each pipe. Took it for a blast, sounds just right....If I can do it, anyone can. :bigthumbsup: All 4 baffles came out in the holesaw.

Just got my first M109R. I have been wanting this bike since 2006. My question is Will this void my warranty?
pick up an extra set of stock pipes and stick em in the garage...if you ever have a warranty issue, change them. you can usually get stock pipes for pretty cheap if you keep your eyes open.

I'm considering doing this mod this weekend. We shall see if I do and if I like it. I'm not much of a mechanic so I've got to keep this thread up for pointers.

To those of you who have done this and posted about it...THANKS for all the info!

I think there needs to be an official clarification of terms. Drilling out baffles VS Debaffling. I believe that I have debaffled my exhaust (see attached pic). Prior to debaffling I had done several versions of drilling out the baffles. In the pic the hole you see is were the primary enters the muffler, my cat and crossover are intact, otherwise it is a straight pipe.
If you want LOUD and deep sound especially when you get on it, then you need to debaffle. At idle, it sounds good, and the neighbors are not going to linch you, but if you snap the throttle or get on it under load this thing flat rours. When I start it next to cars with alarms, it sets them off.

So I drilled out the first 2 pair of baffles . I havent drilled the 1/2 inch holes yet . Its a huge improvement but maybe Im lookin for just a *little* more . I am considering drilling out the 3rd baffle ( last pair ) before I do any drilling of the 1/2 inch holes . Any sound to be gained from the last baffle removal ?

This post here is for de-baffle not drill. We rip the baffles right out.
