De-Baffled

I've got some pics in my album of how I De-baffled my stock pipes. Sounds great.
I took her for a ride today not expecting any power difference, since I still have stock jetting and was already running a tat lean in the mid to upper. I was surprized, she has more pull throughout the whole range. Still alittle lean at WOT, but better than before. Still not the perfect sound, but alot better than stock.

Hey Stumpy,
I just got my 05 this morning... how'd you get the baffles out? Does yours have an air induction in the exhaust? Does it back fire alot with no back pressure? and finally, Will the muffler slip apart at the seam there in the middle?
Just a question or two!!
Any advice can help!
Thanks

Cangrats on getting the bike, As long as you grind out around where the hole-saw cut is,the baffles should slide out with a little twisting. Make sure that the spot-welds on top &bottom are ground flush too(on the inside of the pipe). I used a pair of pliers to grab & pull them out. I'm assumming you looked at my album pics. As for the Exhaust I've "marbled" my bike. for more info on marbleing take a look in the versis part of this forum. It has alot of info on Marbleing and coastering the fresh air induction. My bike only pops every once in a while, usually on a hard decel,and it's usually only one pop. I also turned my fuel mix screws on the carbs 3 turns out from bottoming. Haller if you need any help. thers a lot of nice knowlegable poeple on this site waiting to help.

Use a pair of pliers to pull the baffles out. youmay have to grind more if they don't want to come out with a little twisting.

Hope they never do DMV sound checks in your state. Washington State is checking now. Had a few guys get pulled over and ticketed on the spot.

I don't think they do. Most V-twins around here are runnin un-baffled exhuast, so if there is a law than MO doesn't enforce it.
I had to fix my shifter today ( Bike was stuck in neutral), and as an update to this thread I just got done removeing the rest of the exhuast and useing a long chisle and hammer gutted the rest of the baffles in the mufflers. I also used the same tools to punch through the goats belly to make it strait through. What a difference in sound and a little on the performance. She's real tourqie now and still pulls hard up top. This part of the exaust was a real pain to do, but worth it to me.

Will someone please explain to me why louder is better? Do you really enjoy the ringing in your ears? Or do you feel compelled to do battle with the kids and their fart can mufflers?

Imho, louder is better because people notice you.. I have no base for comparison on drilled baffles, I've heard stock and V&H Cruisers and I must say, I love the sound of the Cruisers, and they are LOUD, but it's the sound I like not the volume, well I do, but like I said, people notice you, and thats a good thing when they usually don't - safety measure? performance boost? sound....

I didn't do it all for the noise, mostly for performance. I hope your not comparing my bike to some "fart can" car that has a higher DB rating than it has horsepower. I noticed a big diff in power, but yes it is a little louder. I hope I'm not coming across as being irritated, becuase everybody has an opinion. I just wanted to let you now mine. I've had a life-long addiction to horsepower. The feel, sound, and the smell of it is my drug.

If the performance actually has improved ok. Without richening the carbs I'm guessing your valves will suffer some burning. As far as the safety aspect goes. The sound follows you it doesn't precede you as much as you might think. The guy in the cage behind you hears it much louder than you. Do you feel safer irritating the squishmobile behind you?
I have no wish to offend anyone here or in traffic. Around here no one really sees motorcycles in traffic except other bikers. People can't even be bothered to use their signals because they are busy yakkin on their cell phones.
Regardless how much sound you produce. Ride safe out there.

I'm running a completely drilled goat with HD Sporster XL mufflers ($10 eBay) and love the sound. It's not loud, but has a nice mellow tone to it when holding a steady throttle. Get on it a bit and it sounds nice. Drag pipes tend to be really harsh with that edgy gritty sound and wtih our high RPM twins, that's not for me.

A 2 into 1 with stainless glass pack muffler would be my choice but that's a custom job costing more than I can pay.

Something like this...
