I have to say that I agree with the remarks in regards to baffle removal. This is absolutely correct as far as the performance aspect of an exhaust. Because of this performance factor we weld in our baffles so they can’t be removed. We want the rider to get the best performance possible.

As far as the noise, I agree in some respect. “Loud pipes save Lives” The general public often times don’t see riders, but they do hear them with aftermarket pipes. It makes them take notice and be aware of the motorcyclist. At Fuggin we come from the custom V-twin market and we design our exhaust systems to have that loud deep quality sound that make people notice. Sure no one wants to offend the non-riding public, but we all want them to know that were there.

If I lost any performance, then I sure didn’t notice. I am quite certain there is truth to these statements. Could the overall length of these pipes have anything to do with it?

The overall length of the pipes does play a role in the performance of an exhaust. The longer the pipes are the more back-pressure is created, so the baffle can be shorter. The trick in designing longer pipes or any exhaust is equalizing the back-pressure. The front head pipe is longer than the rear head pipe in most designs, so now you have un-equal back-pressure. The baffles are designed for each front and rear pipe to equalize the back-pressure. So what happens when you pull out the baffles or modify the baffles! The back-pressure is now reduced and not equal to the front and rear pipe. This causes the motor to work harder. Gas is shot in to the intake manifold and being un-equal pressure from the exhaust causes one cylinder to get more gas than the other making the motor run less efficiently and run hotter. This basically happens in all V-twin motors because of intake manifold design. You can see it happen during Dyno testing.

To get the best performance out of an aftermarket exhaust, leave the baffles as they are. Your low to mid range torque will be higher and your motor will run more efficiently.

I know this was a windy reply and I didn’t address the sound, but that requires a lot more pages.

Doug, Could you take a quick minute to address sound? Bottom line is that I want the deep sound at least as loud as the cobra’s with the baffles removed. I am not a big Cobra fan, but I have no patience and could no longer wait till more pipes hit the market. In the back of my mind, I always figured I would dump the Cobra’s when more was available. Any suggestions?

I had a set of HardKromes on my shadow and loved them. I never would have touched those baffles!

One last thing, Any idea why I was not able to notice a performance issue? I have ridden 3 other Fury's recently and felt they were all the same. Just Curious.

I really can’t say what the Cobra pipes sound like with-out baffles. I have heard sound clips, but I find no computer sound system can duplicate what any pipes really sound like. Our pipes are designed to have deep rich tone. We have an engineering guy that is very particular about how our exhaust, sound. I can’t tell you how many pipes have been tossed in the scrap bin because they didn’t have the Fuggin sound.
Because we come from the custom show bike world, the Fuggin pipes have sound quality that has never disappointed any of our customer.

... “Loud pipes save Lives” The general public often times don’t see riders, but they do hear them with aftermarket pipes. It makes them take notice and be aware of the motorcyclist.

I tried to resist, but well, I just can't. No disrespect to anyone who thinks otherwise, but... I've seen proof of a lot of things that loud pipes do; damage hearing, piss off the non riding public, attract the attention of police officers, get noise ordinances passed, etc... but I've never seen any proof that they save lives.

Personally, I choose to engage my brain when I ride, pay attention to my surroundings, and not put myself in dangerous situations. Riding aware saves lives. Loud pipes are, well, just annoying.

Props to Cobra and Fuggin for recommending keeping the baffles in.

I think Walt has got it right. I would hope that an alert rider would not be on the throttle making exhaust noise when there is imminent potential for sharing your space with another vehicle unless you are using the throttle to get away and then it becomes a moot point .

If it's a warning noise you feel the need for there is nothing more effective than a pair of loud American car horns which are far more startling than the constant roar of a loud exhaust . Not to mention the fun you can have 'cuase the inattentive driver suddenly wonders where the f..kn' big truck is that's bearing down on him . That alone should satisfy even the hardened antisocial biker . If you love an excessively loud exhaust just admit it rather than hide behind a bogus excuse to justify it .

I agree, Walt got it correct. Also, good info from Doug and Cobra. Thanks for the informative post.

I would like to take this moment to come clean. I like a loud exhaust.

Also, I would like to point out that I am a vary cautious rider. My head is on a swivel watching for hidden dangers. I don’t think it is anyone’s intention to ride carelessly under the false since of security of having a loud exhaust.

i like loud pipes.if someone rides with me and dosent like them,they can ride in front.also ,the baffles in the cobras are the same so it want change the fuel input that much.i took time to set the fi2000 and have no overheating or engine problems.oh yea,when people are setting in intersections and they hear my pipes,they dont pull out in front of me.i think they do help.keep the rubber on the ground.

Baffles in or not

I'll add my 2 cents to this thread..
I personally left the baffles in, they sound great and with a lot of throttle applied they can be real loud.
I do also like the fact that I can take it easy and they are at a comfortable level not to piss off the neighbors.
I have been observed by several motorcycle cops now, and I can back it off and they sound just fine.
I do agree with Doug's explanation of the pipe back pressure design aspect.
I can tell you from my personal experience riding around town, since I added the pipes I am no longer getting cut off by cars. (Stock mufflers) (Our main streets are 45 MPH around here, and trust me people are going faster than that)
They are now hearing my presence. I use the rider radar technique of looking ahead 2, 4 and 12 seconds ahead when I ride and has saved me several times. There's no substitute for alertness

The point I'm trying to make is that prior to adding my pipes, I was on a daily basis getting cut off from cars not hearing my presence. (Stock mufflers)
Today people seem to be in a hurry to go nowhere fast. (See you at the next light)
That has not happened since I added the pipes, not to say it won't but so far my presence is being heard.

Do loud pipes save lives?

There are many articles about this, but here is one from:

T Jaussaud Harley Davidson Examiner

Do loud pipes save lives?
Although it hasn't actually been proven to be true, many bikers believe this is a fact.

The motorcycle officers with the Oakland police department obviously believe it too! They have dumped the toned down stock Harley exhaust pipes and equipped all 45 of their Harley Davidson’s with pipes that put out a roar at 93 decimals, well above the federal standard of 80 decimals. In a statement explaining the department’s decision, Chief Dave Kozicki said, "There's an old motorcycle adage that you are heard before you are seen." I’ll bet those cops are happy campers!

Chief Kozicki also mentioned an incident where a motorcycle officer was struck, while riding a bike with the stock exhausts by a motorist who later claimed he hadn’t heard the officer coming.

I guess Oakland’s motorcycle cops are known to ride their Harleys with loud pipes, so much so they were labeled with the nickname “Rolling Thunder” until one officer reported having hearing loss problems. That along with citizen complaints caused the department to switch to stock Harley Davidson exhausts.

Many of the motorcycle officers then complained that they didn’t feel safe riding with the stock pipes. So the department and the cities risk management department did a study. The findings were unreliable. So they decided it would be in the officer’s best interest to switch back to the louder exhausts.

I still feel if you need to rely on another driver hearing you to avoid hitting you, then you've already lost the game.

I also think it's outrageous that a LAW ENFORCEMENT AGENCY would break the law. That just shows their lack of respect for law abiding citizens, and their contempt for the law. Shame on them.

Well put! Now all we have to deal with beside the yakking on cell phones is texting... It appears that you are 8 times more likely to be involved in an accident while texting. While drunk driving you are 6 times more likely. Nice huh?
