Summer boredom and limited cash flow produce interesting things...











Modified Sportster header and a stock RT muffler with the baffles out. Added a bit of torque and sounds great. All for the low low price of sweat and tears ;)

A stock muffler taken from an 89 Harley Davidson FXR-T. I call it an RT for short, sorry about that! : )

I was wanting to try that since XL drag pipes can be had for about $80.
What do you mean by 'modified'? Did you need to bend the header or just cut it?

We cut it and welded it back to get the desired curve.

Would it have worked without the cut & weld? Or is that the only way. Would the Big Twin exhaust have worked better?

Well I'm sure if you were good enough with the heating and bending you could probably avoid cutting and welding. I know I'm not that gifted however. ;)

We experimented with some larger twin mufflers, they didnt seem to fit quite right because of their size, and would most likely had been mounted somewhere on the side of the bottom portion of the bike had we decided to use them.

As for working better performance wise I have no clue. : )

This was soley the product of what was laying around the shop.

I actually just bolted a Khrome Works Dyna muffler onto my street Blast because the V & H can that came with the bike was trashed. It too was "laying around the shop"! I can say the power is better than stock, louder than the V & H, but I think the V & H was a little better powerwise.
I was just kinda wondering how much work a cheap set of swap meet drag pipes would take to use on the Blast.
Thanks.

That looks good. And you could have left the baffles in I assume - if you wanted it quiet.

I just saw this on Ebay, I sent the owner a message and asked him what brand exhaust it was and he said "custom made pipe, sounds good" He didn't give any more details. It looks pretty straight forward. Huge pipe, maybe to big?

Hi all! I've been reading a lot over the past few weeks since I picked up my 2000 P3, but I haven't contributed yet so I hope I am posting in the right place. Anyway, with another horse in the stable now I was window shopping for my old KX dirt bike (I don't want her to get jealous) when I got sidetracked by this:

www.fmfracing.com/products/catalog.aspx?CategoryID =32

What do you think? Has anyone done any experimentation with something along these lines? I read some reviews for the FMF part and the MX'ers really seem to think it gives a bunch of power all over, and works as a kind of resonator to keep the noise down, which I figure is a win-win for those of us who want to avoid any "Imperial entanglements" and of course free some more power from our sweet singles. A quick search brought up only one other mention of the "bomb" and I guess no one really thought about it... I'm getting my welder...

Welcome Dankno!
Well, it'd be custom and you'd have to do the R & D to figure out where exactly to put the 'resonator'. Its along the same lines as the stepped pipes and tuneable White Brothers and Supertrapp. Done wrong it could cost you power. Done right...who knows!

ok so i know everyone is lookin for a good exhaust thats not to loud sounds good, makes power, and doesnt break the bank.....well im gonna try to make one....utilizing the measurements provided by EZ for the lsr design, and the.......KERKER!!!!! using a perforated core, some steel wool..blah blah etc....im goin wednsday to have my fabber look at my design idea... see ez's design has a smooth curve in it. were as the kerker. has a short smooth bend followed by a straight section, and another short bend..... take the powercone measurements add them to the kerker simplicity and viola....i will post pictures, tools, materials, funds and alcohol required to build the exhaust... i plan on test running with a 48 170 jetting to start .028 shim...etc
kerker $429

48 is too big. Thats six steps up from stock and three steps up from a stock "Big Twin" which is running a 190 main and an accelerator pump!!!

Start with minimal jetting, then add to it. (42 or 45/170-no shims). My opinion is that you should start with the same baseline everybody else is using. Otherwise you cant really see an improvement or be of any help by being able to experience the symptoms of running lean (or with stock jetting).
I've seen exhausts running from 'rocket science' to the 'bigger is better' approach. Its amazing what seems like it wouldnt make a difference, does (good and bad).

Again, my opinion!

Thats great of you to take the time to post it here. Thats how Badweb works : )

well im still on the drawing board..lol i went to the drag races with the blast, they dont do bracket racing there. so i ended up starting against a honda 919...i assume you can all go from there on your own. anyways.my dad helps me alot. and he has been researching everything, and as he figures it. the reversion is not a big deal. it actually helps torque from the info he's found. we are starting with the 1 5/8" header salvaged from the factory "swan" adding a 1 3/4" tube from there with a spiral flow baffel to create back-pressure. and a turnout. from there i wanna add a shorty 12" glasspack muffler.
and so on. after he finishes heliarc welding the design together i'll paint it and give it a go... gonna be loud.. probably in a bad way. wish me luck. and i AM open to Critisism. also the kerker/force hybrid is on hold till i locate a fabricator..dangit

Curvestealer, I just finished making my own can. I only did a 2.5 in. can with spiral baffel. I used the Jardine header pipe (after the rivets vanished along with the rest of the Jardine can). Search Flo-Pro Twister muffler. That was the design I used. It sounds about as loud as the Jardine did. It will never need to be repacked.
