What benefits are there if you change your exhaust?

Question

What if you go from a dual exhaust to a single or go from a single to a dual?

Answer 1

if you go from a dual exhaust to a single it will create more back pressure and give you better bottom end torque. When you go from single to dual it will let the engine breath better and give you higher RPM's, greater fuel mileage. It dose not always sound better going to a dual exhaust from a single. I've seen bikes go from a nice deep tone with a single to sounding like a VW Bug with the dual exhaust, due to the wrong size pipes. If your going to do exhaust mods do your homework first it can make or break your performance!

Answer 2

Unless you're talking about the entire exhaust system, including headers to tailpipe, probably not a whole lot other than waking up the neighbors. A lot of people will replace only portions of the exhaust system and leave other parts bottlenecked. For instance, a high flow muffler is kind of pointless when the exhaust is bottlenecked elsewhere.

Answer 3

I can only confirm what Performance Crazed and Mye77 have already said.

And ad the benefit of "style". If you have a low mounted exhaust and you want it up under the seat or both on one side if you have duals and what not. Not a performance benefit, but a style benefit.

Answer 4

Go with Sonny Barger's pipe...Rich Products "Thunderheader" if you own a harley, it produces the most torque and horsepower than any pipe out there, I had 3 different pipes on my fatboy and the HD dealership dyno'ed all three, thunderheader won hands down. http://www.nightrider.com/biketech/
This site will help you out, look at the horsepower gallery and see how many times thunderheader shows up. I have one on my FLSTSC and it's sounds low and loud. Peace.

Answer 5

stick with dual exhaust it's better

Answer 6

all depends on what engine, engien type, performance of engine etc. dual pipes tend to have more deep throaty loud sound. 2 in to 1 usually give best all around performce, and torque.

Answer 7

more power, better sound, fuel safe. Better to stick to your original unless you want more

Answer 8

better gas milege, helps your engine breathe better, sounds good

Answer 9
