He has music when you open the page (for those at work).
I bought em. Eveyone who rides with me says they sound awesome.
Had the bike dyno tuned with these, true duals and AN big sucker. Way more punch.

 

Here you go

 

I bought a set of modified mufflers off Ebay once,while building a groundup.The 124" motor did run like I thought it would.Had to custom order mufflers designed for the 124". Will say the stock modified mufflers did sound some kind of nice.These had a 1" hole straight through the center.

 

Had his mufflers on every single HD I've ever owned (both of them).

Right now, running his *left* Max2 and the stock *right* muffler. Best sound without excessive volume I've had.

Always looking for options though...

 

JohnScrip, I took a set of V & H Ovals, took them apart. Added 10 in. of 2 dia. pipe with a set of holes in them. End result is still agood looking muffler with a mellow sound and no bite on top end.

 

Any one know how to attatch a wav file here so you can hear my modified mufflers?

 

+1 ...would love to see pics of what u did

 

If you anyone wants to hear them , give me your e-mail address and I'll send you the wav file

 

I did my stock mufflers the same way pretty much. I stuck a piece of bar stock in the back end of the muffler and beat on it with a bfh until in pops through the first plug. Keep on pushing and it will hit the next plug. Start beating again and you will pop through that one too. Now go back and dress them up by knocking the edges down.

 

Can you give a few more details or do you have pics?
