Modifying the stock exhaust

I'm probably going to be scorned for this. I wanted a little more noise for my bike, in the end i will get something custom fabricated. I did something similar to my other motorcycle which was a 06 vstar 1100 with great results. Here's a short video of the results. I put the cap back on and it made the muffler a little quieter. I like it for now, just another option for those people who don't want to spend big $ on a remus setup.

Do you mean something dramatic like this: Sorry I can't remember the poster, but they may pop up, take the credit and explain their work.

Looks like an angle grinder cutting disc job to me. That won't make you popular in the neighborhood for early morning commutes to work or Leos with decibel meters!

So thanks to voxmagna i ended up trying what he posted. I'm not sure who did this first, but its a pretty crazy way of attacking the oem muffler. I also like it cause it makes the exhaust short and you have an open view to the rim.

Well I don't know anybody else that did it.

Does that give you enough noise now?

Does your bike sound similar to anything else on the road or track? Pity we can't post up MP3's here, although you could probably find a host - what about YouTube? Will it handle the decibels!

Yup, that's enough noise. It kind of sounds like a harley at idle, but screams full throttle. I will take a better video and post it soon.

2003 k1200rs muffler change

I saw taking the can completely off and adding the end cap off. Has anyone considered adding a muffler? I'm wondering why I can't see anything like adding an adapter pipe and a muffler. Is there a problem doing so, is it cost, or does it just not work?

I like the power I already have. I don't crazy loud, but a little more tone. Does anyone have the same model bike that wants the same? I'm just curious.

I'd love to hear from people about this. Thanks.

Tone? Dremel with the cut off disk. You need the flex shaft then insert into the exhaust and cut 8 or so slots about 11/2" long perpendicular to the opening. That will tone it up....!

I'm just about to do that. I called up a custom exhaust shop and I've been a long time customer. I trust the shop implicitly. They were hesitant because doing an aftermarket muffler may decrease backflow. I'm wondering if making the cut in the exhaust will affect the same?

Those that have done it have any adverse affects from it. Any noticeable gas mileage or power drop?

Let me know. I just so happen to have a Dremel and flex shaft attachment. I've never used the cut off for metal work, so pointing me to the right cut off part would be helpful too.

thanks guys. the info so far has been invaluable.

You may notice a mileage drop...sounds so much better cranking her up coming out of curves that I sometimes don't shift until above 7,000.That takes fuel...

As for mileage in general....I am satisfied.296 ecu chip at 3,500rpm I can beat just about any posted claims.Boring. I only did that once and kept the pics to prove that in my computer.

No power drop that I can feel.Front wheel will still pop up shifting into second at close to the rev limit.Bike is getting older but once a year to check performance.

Anyway...you'll be cutting just beyond the "boss" that one can see in the exhaust.3"-4"in or so?Hard stuff to cut the SS so took 3 disks.Reminds me that I did buy more,forgot how many cuts so maybe a couple more today?
