Maybe you can put a removable baffle in the end of your pipe. That will tame the sound a little bit when you don't want your ears hurting.

I have essentially dual drag pipes with 8" baffles inside, the baffles tame it a little, but not too much at all. I will be welding large washers inside it to reduce flow and help the noise.

It's stuff like that that gives all of us a bad name and forces legislation like SB435 in California. You're killing all your low to mid end power, and without rejetting, top end power and longevity too.

If you just want stupid loud look at that vid i posted. 45 degree bend turn down shorty pipe. You hit 6-7k and its going to hurt ears which is about 125dB. Idle your looking around 100dB or more.

Never understood this.. the 600 depends on revs to make to move. Yet you hit 6K ( not even close to the power band ) and its so damn loud that you hurt your ears...

I love a good rumble as much as the next guy, but with that exhaust I would never ride next to or around you.

ey just to give u a good suggestion... check out the scorpion slip on... it sounds nice and awesome, has a low and awesome tone.

Funniest thing is to sit at the Deals Gap store on a nice weekend, and watch the Harleys pull out of the parking lot. They get on the road and open the throttle, but the bike doesn't go any faster, it just goes louder.

"So I was having a good ride and feeling pretty good.... *pause*"

Look at the very loud and slow moving Harley take off and wait for 30 or so seconds for them to get out of range....


"Sorry, intermission! Anyways, as I was saying... Was feeling pretty good and came around......... "

that was an awesome moment sitting there at the CROT.

Hmmm, wonder when the dB drags will be starting on the hill?

You guys with open pipes are just killing the sport and hurting the motorcycle industry
loud pipes are fine, hell my hindle is loud, but open pipes cost you HP and **** people off

[thetable]

hell my hindle is loud

I never found them loud in comparison to most of the other stuff out there, but damn, they sound good.

My TBR is getting too loud for my taste, I'm seriously thinking about repacking it. Then again, I usually ride further than to the local bike night and back, and all that noise for an extended amount of time, no thanks...

[venturesomerite]

Well mine is all for looks, not performance. If I wanted performance I would have started with something a little sportier than a kat.

Open pipes are loud and annoying, I'll def agree to that. That's why I need to quiet mine down, I just wanted to ride so bad, lol!

I rode with a harley with drag pipes, and a kat with drag pipes is a little less loud riding around, but can get much louder with the higher reving engine.

Duhr but I want my bike to make moar power, and more noize equals more power, duh!

That is what I am looking into doing. I can not validate the dB on the pipe I have for sure. I am looking into getting a dB meter. One of my buddies said it hurt his ears at 6k but everyone else who has been next to the pipe and without a helmet or any ear protection on and i hit 6-7k do not seem to even mind. I really need to verify the dB on the pipe though just to know 100% for sure and to also look into downing the dB to legal limits of 82dB.

A good way to silent up the pipe is a thick SS washer with about 5 holes drilled in it to appropriate size. I have seen Leo Venice cans come with these that really drop the dB pretty good and provide more back pressure in return.

To me I do not mind the sound, it doesnt hurt my ears at all even standing next to the bike.

Nemesis wat size exhaust pipe did u use on that ? I'm gonna work on fabin one up this weekend

I am not for sure the size of the pipe the muffler shop used, it looks like maybe a 2".

It's stuff like that that gives all of us a bad name and forces legislation like SB435 in California. You're killing all your low to mid end power, and without rejetting, top end power and longevity too.

Your state legislator banned (or attempted to ban) .50 cal muzzleloaders because they thought they were capable of "rapid" fire back in 2005.... need I say more?

Also hint if you would read the purpose of the 45 degree bend is to prevent loss of back pressure which loss of back pressure is what adversely effects low/mid power. Just from riding the goal of reducing or eliminating back pressure seems to have been accomplished with the 45 degree bend...

Never understood this.. the 600 depends on revs to make to move. Yet you hit 6K ( not even close to the power band ) and its so damn loud that you hurt your ears...

I just blipped it to 6k. When I am at idle i dont like to rev over 6-7k without load on it, thats just my preference and yes i am aware its not near the power band. Only one guy plugged his ears everyone else didnt have an issue and didnt seem to think it was to loud. I was standing closer to the pipe and i didnt have an issue with the sound either and before you ask no i am not deaf. I am just going by this one guys reaction that the pipe could be hitting 125dB at 6-7k but without a dB meter i can not verify this. He could just not like loud sounds. When i get my hands on a dB meter i will verify the dB output of the pipe.


as for power loss that was the purpose of the 45 degree bend was to reduce or eliminate the power loss from the open pipe.

loud pipes are fine, hell my hindle is loud, but open pipes cost you HP and **** people off

I can not seem to tell there even is a loss of power but its not like im on the bike with a stop watch when i goose the throttle. When i do open the throttle up i dont notice a difference she seems to have just as much pickup and go as before if not maybe a little more but again this could just be a placebo effect. If it will make you happy for testing sake ill pickup a cheap cyberdyne techo/speedo gauge that will register 0-60 and 1/4 mile time recalls...

While i agree there is such thing as to loud that is something i am attempting to prevent here. I dont want to make people go deaf or hurt their ears when riding next or near me. Id be happy with 82dB legal limit but again stated i dont have a dB meter and these are not results i posted before they are estimations from observations of some friends and their reactions. Only one plugged his ears. The rest of them said it was loud but not to loud. Even had a buddy drive infront of me in my truck with the window down and i went by at about 100mph while he was doing 80mph i do not recall what the RPM was at but he said it wasnt to loud when i went by, didnt hurt his ears and no he isnt deaf either.
