Gutted stock exhaust??

Has anyone gutted the stock cans and tried them out? Im not talking just de-cat them, I mean gut everything. Im curious how they sound. My thoughts are they might sound like crap. Im just looking for a cheap way to lighten them and make them run a little cooler. If they dont sound to horrible ill probably gut mine.

I have already checked the stock cans "guts" on the HOW. Looks easy enough to do.

Define gut. If you truly gut them, it will sound like an obnoxious Harley and run like crap until you rejet it.

yes it can be done. i run a truly gutted and reworked can.

But it takes some work. I cut both end caps right behind weld, then you need to hole saw out the exhaust outlet (1 1/2" hole) is what i used. On the back side of can you must cut all the way thru which will cut thru the cat pipe also
After that you can slide the whole baffle assembly out.
I then reweld rear cap back on, welded an 1 3/4 dia pipe to the end cap, then used a 1 1/2 stainless preforated baffle thru can packed with baffle material i suggest stainless steel wool as the normal packing did not last long.
for the end cap i cut a pc off the interal baffle and welded to the inside of can so it projects enough to rivet the end cap on for repacking.
It will work and sounds good but it is loud, i ended up fitting an FMF spark arrestor on the end cap to reduce noise level.

Really?...............Your bike won't run any better and actually worse until it is rejetted. Glad I have left the stock exhaust unmolested, seems like a waste of time and money on these bikes for NO GAIN.

I am aware of the necessary re jet. Did the setup you made weigh significantly less than original or is it relatively the same. Also do the cans run cooler?

The cats, not the baffling, is what makes 'em run hot...

If you want some nice cheap light pipes, buy some carbon cans from a ducati and have a welder make a quick flange to the stock mid pipe. Takes a lot less time than gutting the stockers and lighter too.

Sorry WP Not True ;-) Remove the cats as I did in 2005 and nothing changes heat wise.

1/ The exhaust run through the middle of the bike makes the middle of the bike bloody hot

2/ The standard muffler has 1mm of insulation under the outer skin to protect it from internal heat. This does 5/fifths of fuck all to help cool the outer skin down.

3/ An aftermarket muffler is a perforated tube with 2 1/2 inches of insulation wrapped around it under the outer skin. with the exception of a little conduction of heat at either end where inner joins outer the outer it is well insulated.

4/ The whole standard muffler is designed to function as a cat.

There is only one way to get rid of the heat, get rid of the exhaust.

You can build your own like I did or the GPR is a very attractive proposition.

If you do not like the heat............

You need to move the exhaust system out into the flowing air along with your voltage RR

Allright.

So I have been running a 2-1 setup with a de-cat stock muffler for a while now. It's just as hot as before and really made no difference in sound or performance.

My next route is to use the outer of the stock can and replace the innards with a perf core and lots of packing. Im sure it will be loud, require a re-jet, and still be relatively heavy but it should be much cooler. Im have a stock muffler off an 08 CRF450 that i am going to rob the innards from. I'll report when I finish it...

Hi K2M,

Where do you relocate your voltage regulator to get it into clean air and keep it protected ?

zzzzzzzzaaaaaaaaaaapppp...... dead thread revived

As you start to cut the OEM muffler apart, you will discover that it is possible to gut and reconfigure. You also will discover that it can be a bit of a PITA to work with because the outer shell is not single walled so welding it all back together can be challenging at times.

I believe that the OEM mufflers 'run hot' because the exhaust spends a bunch of time in the muffler traveling between the three chambers before it finally exits. The cat can be a contributing factor, however I do not believe it really makes all that much difference in surface temps one way or the other.

I guess the simple way would be........... anywhere the wires reach. I have changed my bike so much that it would no longer be relevant to a normal LC8.
