But, Sci sucks at searching forums and we did not gain any knowledge of what others did until 'after' we were done. go figure.

I had it all worked out in my head b@stard! It turned out great, just took us longer.

I WILL have a video this evening!}

Excellent R&D guys!

Being that you didn't get a pre-dyno done...did you at LEAST check your AFV's prior to your mods and about 175-200 miles after?

Check em when you can, I'd be curious to know if they increased based upon where you cut & opened her up.

What am I sayin'? You all cut everywhere! : ) I love it! mm

Nope, didnt do any of that. We will see how it looks on the Dyno Sat. If its out of control I can always buy another stock muffler. Till then I am just putting it around.

That and I dont know how to check the air fuel value (if thats what it stands for).

Ok. Here is the video. A have noticed it is nearly the same sound (just a hair deeper, but nothing like my old XB with the D&D on it) while riding down the road. I have not been able to listen to it while someone else is riding it....yet.

I dont know why it is that raspy on the video, but its not that bad in person. anyway, here ya go.....

embeded isnt working for some reason. direct link below.

Sci,

For the heck of it, go into diag mode on your dash and record the front and rear AFV value and recheck every 25 miles for the first 200 miles. If you made a change to pumping flow, you should see an INCREASE in this value over time.

Adaptive Fuel is what I mean, not air/fuel ratio, it's built into your ecu and DASH via diag mode.

With key off, hold both the toggle and the mode button down while turning the key/ignition on...you've just entered diag mode and should show on the dash...

...now toggle through to get to F & R AFV numbers.

Takes less time than it did to type! : )

It helps in understanding how the ecu is learning/adjusting the new feedback info.

This function adds or deletes pulsewidth within the open loop fueling conditions but is learned via closed loop feedback parameters. mm

Yea, Sci would never have known this, he does not 'read' manuals. In fact, your post may be too long. haha

I give the guy credit but from what ive read he did alot of work .But I think it was way more than needed . He took more of the baffling out and hung a dildo looking tube off the end of the bike.I integrated a pipe in the pipe and put some diamond shape grateing to muffle the sound slightly it also keeps critters from entering over winter .This thing has a awesome low thump but not ear piercing when at wot.all the baffling is still there.I ran it at the track prior many times runnin 10.60s and after same results .I really dont think you can beat the stock exhaust if you can just make it slightly louder.Good job on yours i was going to do the same thing but decided to be a little different by not hanging a dildo on the side of my bike.

if ya took all that out i would say you lost some for sure.I added diamond grating to mine because i felt mine lost a little all around and was too loud .I took out those two small tubes that went too the first chamber.

I'm thinking that if you cut a small rectangular hole in the forward (largest) chamber, hack the small tubes and both of the large tubes so everything dumps into that chamber, then leave the stock tips. Weld the plate back in, and you have a stock looking pipe, with the nice little chrome tips, and some rockin sound. Minimal surgery, and easy to cover up.

Might be something to try.

The best part of modifying is you keep the "compliance badge" welded to the can.
The less obvious the mods the better.
Mine has the stock tips, but the exit tubes are cut open into the rear chamber.

Just enough thump, mostly at idle.
Doesn't sound much different at rev.

Awesome work Sci. Now you got me thinking about tearing mine apart for a third time. damn you. LOL

However after listening to your video and then again mine I am not sure how much more sound I would gain.

Here is mine.

My wife says "Y'all are all a bunch of Geeks."

But then she goes and says something endearing like..."But that's O.K.! I Love Geeks!"

WTF does she know. She rides a F***ing Scooter.

DAMN YOU! That sounds perfect! I think the pipe I put in is too long (goes in about 8 inchins into the chamber at an angle heading torward the front of the bottom pipe) Listening to yours I want to take mine apart and cut some off. lol

Each to thier own, I like it a whole lot better than a 3" gaping hole pointing at the sky and I wanted the exit pipe to face away from the rear rotor and swing arm. We spent some time getting it to follow the lines on the muffler as well as the swing arm. }

All in all, it was a science project that let me practice welding thin metal before I touch the 'cuda... and, did I mention... much much beer! We even finished the job off with a celebratory Steak grilled to perfection. My wife poked at us during the process but she sure did enjoy the steak that followed. : D

Great feedback all around, wouldn't be any fun if everyone liked the same thing!

Another stocker/reworked`deep mild rumble, not too loud but big improvement in flow.

Heading out right now to rip it...hoping for an increase in AFVs!
