Best 2 Stroke Silencer

In this article, we showcase all the Best 2 stroke silencers that are available for your dirt bike!

There is nothing better sounding than a well-tuned 2 stroke exhaust ripping up the track or trails. I mean the sound AND smell is something of legends, in fact in college I tried to convince my schoolmates that 2-stroke exhaust cologne was a good idea for our business class project.

I lost.

Still, that hasn’t changed my love for the 2 stroke dirt bikes. 

For a while there I thought the ole 4 stroke would be the nail in the coffin for the 2 strokes…..

Offroad and enduro riders for the save!

Well, that did not happen and there is an alive and thriving community of 2 strokers out there.

However,

Slapping a 2 stroke header pipe and silencer is a great way to get more power from your dirt bike. Who doesn’t want that?

Below is a list of all the dirt bike 2 stroke silencers that I personally know of… let me know if I missed one.

No matter which one you choose for your trusty 2T I am sure it will make you faster than all your buddies.

There are two parts to a 2 stroke exhaust system

You have a front pipe that is called a few different things (see below) and we have an entire article talking about these pipes for 2 strokes – CLICK HERE

Why do you need an Aftermarket 2 stroke Silencer?

Modern 2 strokes actually come with pretty good closed course exhaust systems. However, that does not mean you cannot get more power, a better powerband, and a lighter silencer for your 2-stroke dirt bike. 

Adding an aftermarket silencer is not only cool for the bling factor you can add a better power curve, lighten up and also sound better.

Most OEM dirt bikes come with closed-course silencers and exhaust systems.

What does this mean?

If you plan to ride your dirt bike offroad or on trails that are not private property, out here in the west you are required to have a spark arrestor to help prevent forest fires.

Lots of races also require a spark arrestor.

Here is a list of the 2 stroke silencers that have a USFS approved spark arrestor – CLICK HERE
