How to: Silence by 1/2 your Two Brothers Exhuast

check out this link. Don't ask me about it, I haven't done it, but it's another forum and apparently it works!

Two Brother's Exhaust Sylencer Mod - Sportbikes.net

thats pretty sweet

Simple and Sweet, thanks.
b_d43 made something similar but he machined the piece, so it looks more "professional" like it came from TB.

+1. Thanks
I was think of doing the exact some thing but placing the two !@#$ ( I have no idea what there called) on the db killer side and painting them black. I need to try this when I can find the time. The only thing that worries me is creating excessive back pressure....

Glad he painted the second set of disks, got rid of the "crosseyed" look.

doesn't this negate any kind of minimal performance gains that might have been gained by putting the pipes on?

When it comes to backpressure, in general it's dependant on the diameter of the outlet. Since in that person’s design and what I considered the diameter of my discs to be came from what the stock outlet diameters are. I made mine 1” diameter while the stocks are a tiny bit smaller. If you’re going to make discs I would not recommend port diameters smaller than the stock ones. As for the performance, I think even with the 1” diameter port discs in place is still better off in performance because the stock mufflers are not a straight through system therefore inherently must have more back pressure than the TB’s.

There are some interesting articles on the web about motorcycle exhaust design and theory. It’s internet stuff so true fact or not, consider the source. Here are some good links for a good read…..

Ye....I should have read the whole thread...:spank:

might try that

Try repacking first. I have posted it up some where before. Two Bro's did a horrible job with the packing. There is hardly in there.
