Stock baffle mod with sound clip
A lot of us have tried drilling and punching and never could get the right sound. Here is my take on a stock baffle mod. First my bike is an 04 Heritage fuel injected and I could never get the right sound with Screamin Eagles, Vance and Hines, etc. What I did was purchase at Advance auto two 1 3/4" x 18" tailpipe extensions, less than $7.00 each. I drilled 4 rows of 1/4" holes 1" apart and as I drilled it pushed though and left a jagged edge, see pick. With the stock muffler baffle completely pulled out except for the wire mesh part, I inserted the new pipes with the holes drilled in them. They are a snug fit but that's actually good. I put a small bolt in the end to hold them, but you might not even need that. Seems to be enough back pressure, the bike runs great. I do have a race fueler and an S&S air cleaner set up. Of course this Harley sound thing is whatever you like just thought I would share and did include a sound clip.......

I think it would sound just like 1 3/4 drags, raspy. Try it without holes and if it's too loud start drilling. My thinking on the holes also is that the sharp jagged edges, the drill press left, will give it just enough back pressure. It seems to run just fine...

Hmmm, I just might have to try this. Seems like an easy way to hold me over untill I get my big radius black pipes.

I think you oughta just take the frickin' pipes off and just keep them off. You might just get pulled over the a LEO and, at that point, you'll probably wished you had spent something..., instead of on the ticket you'll likely get.... WTF!!

Don't know how they are over in Wheaton, but they don't stop bikes for loud exhaust over this way. On top of that, I want the bike loud whether I get tickets or not. If I was worried about tickets, I would have left the bike stock.
