But this answer can't be found in the shootout. I have a Jardine muffler(with K&N and Race ECM), for some people this muffler is too loud so they install the quiet insert. Well I guess you could say I created a loud insert, by putting a piece of pipe all the way through the center core of the muffler creating a straight through exhaust. My question is, will this cause any problems? I figured it was no different than a Force exhaust with no baffles installed. I really hope it's ok because it sounds awesome and believe it or not it's actually not so deafening at highway speed and it runs great. Please tell me what you guys think.

Danman2540,
IF it runs great and ya like the sound go for it, However I think it still wd. be different than the Force which I run, as the Force is more of a megaphone or whatever one calls it....

Having said that I love the force on my 12 while still using the stock 12 Header...

Yea I know someone with a Force pipe and it is louder, I was just saying I don't think mine could do any more damage than the Force would.

Yeah your probally right, oh I do run a baffle but I don`t think it quiets it down any, but was going to run it without ,but never got around to it, some said was better to run with the baffle, but like I said never tried it..
If it puts a smile on your face, and it works good cool....

Put it on a dyno and check the a/f ratio through the full rev range or it could be expensive when you discover it's running lean right in your average rev range.

tuning can be problematic with what is essentially a straight pipe.

Your Buell carries enough torque to mask the relatively narrow power band a bit,
but you do need to get it on a dyno to be sure you are not running too lean anywhere.

I have a Jardine on my bike and I'll be re-packing it this winter. The quiet insert ,
for me, is a good idea if I'm going to be droning on the superslab a lot. If that's
not in the game plan then neither is the quiet module.

I like the look on H-D riders faces when they hear me coming, turn to look, and.....
They are confused by seeing a fully faired sport bike, not a hog, rolling by. Priceless!

Well I don't know where theres a bike dyno around here but how could it be running anymore lean than with a force with no baffles installed?

No one runs a force without some sort of additional fuel added.

At least no one that runs one for long.

do you mean more fuel than the race ECM adds?

yup, I can't recall anyone running the force for long without more fuel due to excessive lean conditions.

Well that bites, I guess I'll be taking it out then because we have enough problems without creating them intentionally. Well, thanks for letting me know even though it's not what I was hoping to hear, I'm glad I asked.

I've been running a fairly gutted 9 muffler on my 12 for well over 1000 miles with the stock ECM with no problems. I bought the muffler gutted, then cut it open and put a very coarse (1/2" expanded metal) screen over the outlet pipes inside just to keep the decel popping down. I also welded a larger outlet on since the 9 uses a smaller outlet pipe.
It did what I wanted- almost. The big 2k rise is flatter (I wanted that) and it is very linear throughout with a pronounced rise at 4k. I guess you could say it is therefore not linear, but there are no flat spots, bumps, or dips. The only thing I would change is give a slight amount of peak for a bit more in the 3-4 range.
But, it runs good except during warm up at steady throttle where it will occasionally hiccup. $27 plus $3 for header paint. I'm happy. I also don't think you can make it lean enough for damage without it running so poorly you wouldn't ride it- my $.02.

From the factory the EPA mandates a very lean mixture.

Even if all you feel is a little "lean surging" at steady throttle it can do damage to your engine.

I've seen motors that were "just a little lean" blow very quickly.

Just because someone has gotten away with doing it for a while does not mean that it
is good for the motor to run it lean.

That is anecdotal evidence. You need to monitor the A/F ratio either on a dyno or
via an aftermarket gage if you want to do it right. Unless you can afford to gamble
with your motor. I can't. A dyno run is cheap in comparison to a re-build.

Go with what makes you happy. I'm trying to help here, not ruin anyones fun.

Brian: I run a Force with the stock ECM and love it! It does pop some on decel but that is the only issue I have had. It runs like a raped ape and has awesome torque where I like it. (how's things been by the way?)

Agreed...not for everyone but I like it!
