Well, I was set to de-baffle my HP's last weekend, got the end caps off and hole saw ready, but thought I'd ask for any words of wisdom before doing so.

I was told that all I need to do is make one cut on the exit end with an 1 7/8ths hole saw and pull the baffle out because its just crimped into the other end. Is this true? Anything else to look out for?

I did some searching here and I think I saw Louis ask for some advice and Riv responded with just about the same thing I was told.

I want to double check with you guys before making any cuts.

Good luck on that one, I tried that a couple years ago and could not get the baffle out due to the elongated shape of the baffle.

Step-by-step

Are there any plugs that you can remove before you remove the entire baffle?

I just now hole-sawed the plugs out of my mufflers this month. I LOVE the way it sounds!

Maybe EUROVROD has the [email protected] Sturgis.

I'm almost certain it's crimped and wedged in tight at both ends for stability.

What do you mean by "plugs" Dave?

About 10 inches from the tip of the Screamin Eagle slip-on mufflers, there are 1-1/4" plugs welded into the bores. They resemble motor freeze plugs in shape and thickness.

I modified a 1" hole saw with an aluminum-bronze sleeve to center the saw in the pipe. When I drilled the plugs out, it left 1/8" wide rings intact where once were the plugs.

Because I was doing it as an experiment (and I don't want to run it without dyno-tuning), I made some 3/8" thick aluminum washers to restore the plugs for now.

I truly love the way it sounded with the plugs drilled out. It made the exhaust tone deeper and much more powerful sounding, but not too loud. As soon as I can, I will remove the temporary plugs and have it tuned with them out. I CAN'T WAIT!!!

If your baffles have plugs, you may be able to drill them out before you remove the entire baffle. What could it hurt to try?

Wow, I wish this was the case. I have a feeling I'm going to need a 3" hole saw and a welder at this rate.

When you modify the stock slip ons can you leave the fuel system stock or do you need to get a fuel manager.
These bikes already run very lean. Expanding the exhaust in any way only makes them more lean and therefore more likely to burn a piston. Therefore, with any exhaust modification that decreases pressure, you should add fuel.
