Bonneville America Forums Forums Technical Forums Exhaust My first mod.

I cut out the end baffles on my stock pipes this morning. I can't get over the difference it made in the throttle response; and it sounds good too.
I like the sound as it is for now, but the next thing I'm going to do is the snorkel-ectemy.

Poor sole, lost another one have we?
Sounds like you're already on your way to "Mod Heaven"
Hide you credit cards, delete Brents site from your favorites, stop looking at the bikes here. There's no stopping once you start.
You have been warned, let the small fix keep you going or you'll be a junkie soon. And for god's sake, don't even think the word chrome.

Now THATS funny ! The resident mod guru who's credit card has seen more action than than Chuck Norris and Rambo combined giving "don't mod" advice.

It's a bit like smokers who look at their kids and say "smoking is a filthy habit *puff puff* don't ever let me see you do it!".

Anyway, I'm off for a smoke and to work out my next mod

I started last month by removing the end baffle,then a couple of weeks ago I drilled three 1/2 inch holes in the next baffle,sounded better still. Today I removed that baffle altogether and got the sound I was looking for,loud enough to hear over the sound of the engine and turn heads, but not obnoxious to me after 100 miles or so. Someone stop me PLEASE!!

Why stop, it all started with a chrome choke knob from brents site. No w I have a big list of things I want.

duck

i removed the AI, and now I can't stop doing things

it's that C word .... (chrome)

I removed the end baffle, which was difficult because it is welded to the pipe, and I didn't want to damage the chrome.
the next baffle, however, is welded to the perforated lining and I knocked it out in just a few minutes. It sounds great to me, not at all loud. I didn't really want to do any irreversible mods, but on two separate occassions I had admirerers say "start it up, I want to hear it". I also had a cager try to change lanes on top of me.

how do you get out the baffles, I have been reading on here but can never get a really detailed answer. Do you have to remove the pipes?

I did the mod with the pipes on the bike. All I did was use the biggest drill bit I had (3/4"), and I drilled out the tube. Then I used a 1 3/4 hole saw, and I cut out the baffle. Real simple.
Thats for the end baffle. I haven't done the next one yet.

I started by sticking a wooden dowel in the baffle pipe and wiggling it around til the 2 welds broke. With the pipe out of the way, I cut the baffle plate out with a bi-metal hole saw, kinda ragged because there was no material for pilot bit, saw jumped around. Rim of first baffle still in there. Started on second baffle same way, took a lot longer to wiggle little pipe loose, no room to wiggle. After those little pipes were out, stuck a 1/2" piece of galvanized pipe in the ragged hole and hit with hammer to enlarge it, the whole baffle plate came out because it is only tacked to the perforated lining, not the chrome pipe.
Sprayed some Hi-heat flat black in there and that was it. Very happy with sound.
