Does removing the baffle increase power?
Removing the baffles will change how the engine runs. It will usually cause the engine to run leaner (less fuel), and a lean mixture burns much hotter that can cause damage. Removing the baffles will also mess up the power curve of the motor. Usually loosing power down low and gaining a slight amount up top.
Do slip-on exhausts improve performance?
Slip-on mufflers won’t improve horsepower or performance. Slip-ons are mostly for decoration and noise enhancement. Installation on some bikes may require bodywork done by a professional at a shop.

How do you remove the exhaust pipe on a Harley?
Attach a drill extension and hole saw to an electric drill. Cut through the end plate surrounding the baffle opening. The baffle is welded onto the end plate at the back of the Harley. On some exhaust pipes, there may be a set screw holding the front of the baffle in place. This can be removed with an Allen wrench or screwdriver.
What happens to an engine when there is no muffler?
This includes bends in the tubing, catalytic converters and mufflers. Exhaust restrictions increase pressure in the system, which keeps used gases trapped inside of the engine’s combustion chambers. These gases take up space that should be occupied by fresh air and fuel. The end result is a loss of engine performance and fuel economy.
How do you make a muffler on a Harley?
Use a power drill to cut out the baffle, the long cylinder in the middle of the muffler. Attach a drill extension and hole saw to an electric drill. Cut through the end plate surrounding the baffle opening. The baffle is welded onto the end plate at the back of the Harley.
Why do you need to remove the baffles from a stock exhaust?
It depends on if you’re talking about drilling your baffles, or removing your baffles. Baffles are essentially like a gun silencer: the exhaust gas (and noise) is diverted into chambers and pushed through materials (usually fiberglass) that break up the sound waves and slow down the gasses,…
Is it bad to drill baffles on exhaust?
However, since exhausts are tuned to have a certain note, the change in the tone that comes from drilling holes in the baffles can be sometimes… undesirable. Drilled baffles often sound “tinny” and have a treble overtone that sounds like someone is farting into a tin can.
How big are the holes in stock mufflers?
The holes in all the internal baffles are 3/4″ so you are not dramatically improving the flow through the mufflers. The sound is a little deeper and about 15% louder than stock and doesn’t sound like a sewing machine anymore. This is definitely worth doing if you don’t want loud mufflers but can’t stand the sound of the stock mufflers.
How are rear baffles held in place in a pipe?
The rear baffle is held in place by a rear flange and an inner flange. The baffle is tack welded in two places to each of these flanges. Use the hole saw to cut through the rear flange of the rear baffle. This gives you a nice smooth cut.
