Home made baffles write up. Monster thunder copy cat
I didn't like the sound of the stock exhaust so I cut, hacked and drilled on my stock baffles. I couldn't get the sound I wanted and I wasn't worried about destroying my stock baffles because my fall back plan was to order some Monster Thunder Baffles from bigcitythunder.com Well, I gave them a call with the specs of my X-Bow exhaust in hand. Pipe I.D. 2-5/8" and baffle O.D. 2.6" (just a hair under the pipe I.D.) Turns out they don't make baffles that large for the X-Bow exhaust.
I talked to a forum member about making a set similar to the Monster Thunder original series but then decided to try it myself. I ordered a section of 2" O.D. aluminized steel exhaust pipe, four 2.5" O.D. to 2" I.D. aluminized steel exhaust reducers, a couple 3/4" O.D. steel washers and a couple 1/4" - 20 steel hex head bolts from summit racing.
I measured and marked the reducer 1.5" up from the step down, then wrapped duct tape around the reducer at my mark so I get a straight line all the way around the reducer and marked the edge with a black sharpie.
I slid the small end of each reducer over the pipe so that the edge of the pipe stops right before the reducer enlarges. I tack welded each reducer just enough to hold the pipe incase I need to grind off the tack weld and adjust.
I used a ¼” drill bit to get my final mounting holes on the baffles, I wallerd the bit around so it’s not such a tight fit getting my ¼” bolt to slide in. I also ran a bead around the entire reducer on the inside (closest end to the engine) just to prevent any possible whistling. It’s not pretty, I’m not a welder. Because of that I’m almost not sorry about the blurry pic.
And here it is, took me 3 hours which is probably longer than it should take.
I must say, I'm a happy biker. This is the sound I was after. You can definitely hear it at an idle, sounds like some muscle when you rev it. I took it for a short ride and it has that nice deep rumble I was looking for.
Wow Rebel, very impressive. While it doesn't have the potato potato thing it definitely has that American muscle sound. First time I ever recall hearing such a voicing come from behind a Victory. And who ever guessed that all it took was dangling a washer at the output?
Now for the important part. How does the bike run when it's not idling?
