Exhaust

Rather than pulling your baffles you may want to consider replacing them with different or aftermarket baffles. Unbaffled long shots may sound like a monster but you will lose most of your low end torque in doing so. Also removing the baffles won't necessarily give you more flow. Aside from reducing noise, baffles also help prevent reversion and maintain the required velocity of 300 fpm in larger pipes.

Just about any change you make to the baffle is going to require a change to your power commander. Rather than gauging your exhaust tips I'd check your plugs for any apparent fouling.

If you are looking for that LOUD unbaffled sound but want to maintain power, there's a cheap trick that works well. This is similar to what a Thunder Monster will accomplish for alot cheaper.

1. Find a deadbolt door strike
2. bend the door strike to form an "L" shape
3. mount the "L" shaped piece on the same bolt that holds the baffle

The farther back inside the pipe the better this modification works. I also saw someone use two per pipe to tune the exhaust note even further.

I've been in the process of testing something I fabricated which has a similar effect, but a little more refined than a door striker. Once I finish testing it I'll share it here and maybe get others to try it out.
It should look something like this

No, actually the L shaped (bent) piece of metal acts as a barrier. The bent piece is in the path of the exhaust to deflect. If you look at the drawing with the circle, you are looking into the tailpipe. That view shows the bent metal as it would appear inside the pipe following the baffle, or if in place of the baffle if none used. One end of the "L" would mount to the baffle bolt to secure it.

Make sense???

another way to do this is to use a flat washer with a bolt welded to it. the bolt will will be double nutted. drill hole in muffler, as far forward as you can, stick the bolt through the hole and use the other nut to secure. you can now adjust the flat washer like a flue on a bbq pit or fireplace. i hope this helps. use a big flat washer with a fair sized hole to start, and keep checking plugs for rich/lean situation. i dont know how to draw on a puter so i hope my explaintion is sort of clear. if not let me know and i will answer your questions. just another way to skin a cat.......

yes.....you need the backpressure, and with these mods you are able to adjust the noise level. when doing mods, monitor your plugs for lean/rich conditions....very important!

i havent heard "kazoo" forever.....i was quite good on one, also the wax paper over a comb........then there was the "jews harp!!":roflmao:

It will sound cool be loud and piss off everyone around you, I know I used to do it on bike nights, had some fool up there trying to make noises with a crotch rocket loved to show up and wind it up.

So I pulled the baffles, when he went to do the nightly ritual I fired it up and drowned him out, of course it had a lot of people upset and with their hands over their ears LOL

Will kill the low end those pipes do that anyway so you will be loosing more power.

One trick besides the others you hear is to cut the baffles down about 50% that will get you backpressure and more sound.

Also before drilling a hole in the muffler get a bolt that will thread through the existing baffle bolt hole, then run a longer bolt up into the muffler there's your restriction to help tq.

Old trick was to get one of the bolts with the head bent over to form a O at the top like a thumb screw, feed it through the baffle and nut it on the outside. Same result.
