My wife actually found my stocker (I thought I tossed it) so I have taken it down to my school's welding shop. One of my students is going to cut it open for me so I can then look at the guts and figure out what I want to do with it...I was trying to figure out a good way to use a glasspack (i.e. cherrybomb)...who knows. I will post up what I find inside it (pics) and find out any ideas that you guys might have in tweaking the stocker.
Mostly cuz I am a little bored and want to try something different....?!?!?!?!?! |

The stock unit is very heavy and restrictive. I have a SSR2 and a two brothers. I have about 10,000 miles on the 2bros and it is just starting to get noise maybe an option. |

STOCK MUFFLER: Heavy, yes !!!
"BUT" it can be "PRODUCT IMPROVED" and you will save $$$.$$ and it will not self destruct as
easily !!!

It is easy to open up the stock muffler and adjust it's noise level and restriction. I have been happy with the modified stock muffler on my M2; higher fuel mileage, better feel on acceleration, and I have been able to open it up in steps until I reached the desired noise level.
I now have a Wileyco on the S3T which I bought on e-bay. I like the appearance and want to try it out compared to a modified stocker. It would have cost me $25 to have another stock one welded up versus the $115 I paid for the Wileyco. |

Book an Lafayette, I kinda get it but don't...
If you just add holes, what happens besides less restriction and more noise?
The V&H makes it a PITA to adjust the primary too. [didn't need it, i was 5/8" plus, I guess the chain bit into the new shoe] |

i gave up noise/w my last 89 inch XL(BUB baddogs). Noise is overrated.I've given up "some" HP to aftermarket exhausts,but then again if i wanted more HP i'd just buy the whole engineered package in another motorcycle. |

LaFayette, I sent you a PM. I would be interested in your "product improvements" on the stock unit....
Thanks

When you cut open the stock muffler, you allow the exhaust gas to flow from the exhaust header, straight through to the end of the muffler where it then makes a 90 degree turn, flows through some small holes, and then out the outlet.
Prior to cutting open the muffler, this exhaust gas would have flowed back to the front of the muffler and then flowed one more time to the end of the muffler and exited. In other words, the stock muffler makes 3 passes before exiting and a modified stock muffler makes one pass.
My seat of the pants experience with the modified stock muffler has been:
1. A modest increase in noise level. Not to loud to wake the neighbors when I leave for work at 6:00AM and less then the wind noise at 70MPH.
2. A better feel when rolling on the throttle.
3. An unexpected improvement in fuel economy.
For a little sweat with a hacksaw, dremel tool, and grinder, $25 to a welder to weld it back together, and a can of high heat black paint I am satisfied with the results.
A further side benefit, I pounded the dimple under the drain plug much deeper and wider so it is easy to get it in and out when changing the trans oil.

So just cut the rear end off and reweld it?
I guess once you cut it the rest will become apparent? |

Yes, you cut the back end off around the existing weld. If you use something like a hacksaw or a band saw you will also be cutting through the pipe that leads to the outlet. If you use some type of a cut off wheel, you will still need to cut through this pipe with a saw.
The end cap now falls off. Once inside, you may want to cut back more of the pipe you just cut through. You will also see the end cap of the pipe that comes from the exhaust inlet.
Now you can have it welded back together or drill a few more holes in the end cap of the inlet pipe before welding it. I did not drill any additional holes at first. I tried it for a year and then decided to do it. With an 8" drill extension and a 1/4' bit I can reach inside and drill holes into the inlet pipe end to further reduce restriction.
That's it. A little paint and it looks good as new.

Now that we have established that, what about those ghastly looking stock airboxes?
I keep hearing about "snorkles" and "still air"???
Is my CF cool looking oval AC a lot better than a reworked stocker? [still have it] |

I don't know which is better, but I know that my stocker box is gutted. I may end up trying out Buellistic's "Force in a box" just to see if there is any difference between the two.
If I could post pics, I would show you what I was talking about... |

Silas,
I've re-done my stock airbox-with great photos and advice from Slaughter.
Because I also changed pipe and ECM at the same time, I can't quantify the improvement of the airbox changes alone.
There's no doubt of the improvement overall with all 3 changes.Very crisp throttle response and if there's a flat spot I can't feel it.It just plain PULLS!
However, the UGLY is UGLY is UGLY. I'd like to change to a unit that exposes the front of the engine, but right now it's a money thing. In the meantime, it works so well that it takes a little edge off the ugly, and even I can't can't rationalize changing "for better performance". Its just cosmetics, tempered by "form follows function".
Let me know and I'll try to e-mail the great self-explanatory pix that Slaughter sent me.greg |

I finally got around to messing with the stock muffler modification. I took my stocker to a custom exhaust shop and asked the man to band saw the end cap off. I asked him to cut back the tube to the exhaust snout, so the exhaust goes from the header, to the inlet tube in the muffler, into the rear chamber and out the snout. I was gonna try Lafayette's extra snout mod, but really wanted to see what was inside, so I went with the Bookyoh mod. I decided not to add any holes to the end cap of the inlet pipe.
The muffler man welded it back up and I paid him $50 for doing all the work. I painted the thing with some hi-temp. Needed a Z-bracket [$15] but already had the y-hanger kit from American Sport Bike that included the stock rear muffler strap.
Bolted it all up and went for a ride.
It's quieter and seems to have more power during a roll on, but may not have as much top end.
It sounds kinda like a cigarette boat..."blub-blub-blub".
I like it! |

Glad to hear the muffler mod worked out. You can always add a hole or two in the end cap later if you want a little more sound. It is a straight shot from the muffler outlet pipe to the end cap.
