Ive been looking into the shorty single ex systems. I didnt like the leo vince system, I cant find a pic of a kr tuned system on a busa and didnt like the 1500. price .
So I made my own, I started w/ a stock pipe donated from the board. I cut up and new gsxr650 muffler just for the tip and gutted it .
I used some 1 7/8 mandrel pre bent from the local hot rod shop to form the 2 into one. I knife edged the inside where they come together.
I mated the rear into 2 1/2" into some more pre bent up into the the tip section.
While tacking the system together on the bike I realized i could keep it all one peice and left it that way. I wrapped the system with ex wrap as it was 2 inches off my heel. And I dont get any heat off of it at all.
Only downside is its un-godly loud , so im working on a baffle now.
Flame away.

We made a full custom system for a Turbo T-Rex from scrap stainless parts and had Area-P make me a 2.5 inch core carbon muffler to go with it. Came out pretty decent....our first try at it.

(forceofnature @ Jul. 21 2007,04:57) 197 at 7k!?  Damn that is ear splitting loud.  What distance was that measured at?
about 3 feet back. Ive had grown men ask to hear it , at idle its deep and very rumbly and when I twist it they wince ,jump back and hold their ears. Then they ask when will their ears stop ringing.
Thats why im working on a baffle now. Dont like to deafen friends ya know.

Need to check decibel meter- 150 decibels will make holes in solid concrete according to physicists. I believe loudest recorded rock band weighed in at 117 or so...

As for flames, what kind of small-thinking turd would flame creativity?!? That took a lot of work, props to you. I'm not sure the can is MY cup of tea, but if everyone liked the same thing life would get pretty boring!!

I'm playing with exhaust fabrication now myself, but just cutting and bolt-on type, I have no welding skills.

Wish there was a cheap header 4-1 available...

Anyone know of a replacement header only that can be purchased reasonably?

Dude , that is awesome, "Harley guys complaining that is too loud"? daymn, I love it.

In my book any custom build exhaust seats on top of the list .
Everyone can buy $1500 Akro, very few can build their own.

Hope I don't get flamed for this but: Why isn't there an undertail exhaust for the Busa?  Clean look on bikes that have one.
I was looking at the Boz exhaust for my bike.  Unfortunatley I can't weld either.

I like the look of your exhaust
