"How it works: DMH Electric Cutouts are designed to better your cars performance and feel. The cutout works by welding into your stock or modified exhaust. They can be placed anywhere after the headers. To open the cutout you press a switch, which opens cutout, releasing your exhaust. This enables you to bypass your muffler, increasing horsepower and giving your car an extremely throaty rumble." - DMH Performance.

"no ones louder than it... don't care if it's a Mustang, Ferrari... I don't care what it is, you're the loudest thing..."

Honestly the dual exit muffler deletes sound louder/better than this in person since the sound actually projects out the back of the car instead of at the ground where this cutout likely directs the exhaust underneath the car.

Don't want to throw anyone under the bus, but let me make it clear. It wasn't me who said that.

Anyway here's a couple of pics from underneath the car.

It's actually pretty interesting. I've seen something like this on a WRX but it was by JDM:Password. How much was it?

jakev9041 · 07-16-2013, 06:26 PM

$620 including install, the video isn't all that great at illustrating how loud it truly is, it isn't just mindlessly aimed at the ground either, and yes it is in fact louder than any stock vehicle I have ever encountered, period.

utekineir · 07-16-2013, 06:28 PM

I heard this car the other day, cold start.

It was pretty loud, basically neighbors putting flaming bags of shit on your door step as payback if you use it early or late loud.

Calum · 07-16-2013, 06:32 PM

Why put it right under the driver/passenger instead of just before the 90 going into the muffler? That's gonna spew a lot of heat and is gonna be very uncomfortable in the cabin. The transmission and rear diff are going to hate it to I bet.

DJCarbine · 07-16-2013, 06:53 PM

That almost sounds quieter than my current exhaust setup lol

Reminds me of the Varex muffler, which is a bit more refined than this, but the same idea. Butterfly valve in the exhaust remote controlled by an electric motor. I really want one, but they don't have a kit out for the FRS.

JimmyMac · 07-17-2013, 12:53 AM

I hope you don't end up like the guy with the melted bumper...

Yeah, I have been thinking about having something made using a universal Varex... mainly for the early am and late night cold start... that first 30 seconds while the timing is at -10* and the throttle plate is open is just too loud for my taste, and is about to be even louder with a catless header. Once the idle kicks down it's fine.

FRSFirestorm · 07-17-2013, 08:04 AM

Generally the higher the compression of the engine the louder it is unmuffled. Cam timing (dynamic compression) also plays a factor. Being the car is static compressed at 12.5:1 it will be loud.

I had dual electric cutouts on my last ride. They are pretty cool. Beats the hell out of climbing under the car to uncap an exhaust.

Richard Cranium · 07-17-2013, 09:01 AM

My buddy has this on his Audi A6 2.7T - APR tuned, intercooled, meth-injection...he's got stock exhaust with the cutout after the cats though. Not nearly as loud as I would've expected, but the fucker screams down the highway.

DJCarbine · 07-17-2013, 09:04 AM

I dug up an old video of my 60's mustang with electric cutout....
It was filmed with a potato in the early 2000's
It is the same DMH cutout the OP has

Electric cutouts are fun
