Auger Style exhaust silencer inserts

[Jiggaman]

While I love the sound of my Ark Grip Exhaust the drone on the highway is a little much. I've sound deadened my trunk as far as I can go with it. I found some 3" auger style exhaust silencers that would fit in the straight runs from the axle back break point so very easy to install and pretty inexpensive for what they do. Has anyone every tried using these before? Is it going to ruin the sound at WOT?

Very interesting alternative.

Let us know if you decide to go this route.

Ive never seen that before, any website that explains how it works?

It baffles the airflow, plain and simple. The waves of sound and air pressure have to change so they can rotate their way out. Crazy disruptive. But if it's sound not airflow that's baffled, it would be cool.

My buddy uses those from time to time on his sidepipes, depending on the current build. They do cut sound, but will hurt HP a bit.

From what I've been reading even though it does effect airflow the back pressure it creates is minimal. I have a welder friend who has access to 304 stainless tubing and sheet steel so we are going to make or own that matches the material of the exhaust. I'll be making sure I have a way to remove these if they do block airflow but honestly they can't block it any worse than the stock exhaust. If it makes it sound terrible though, that will also be a reason to remove them. Once I get these installed I will let people know the results. If you are interested in more info, check out Amazon and read the reviews.

I was wondering if it would hurt the hp, thanks for this.

Thanks Kazz

I will only be able to go by my butt dyno but I'll let you know how it works. Perhaps having one or two coils could dial back the sound without creating as much obstruction. Will be an interesting experiment.
