Well. 2-Step works!

Just installed the 2-step relay into a buddies car, and well, it works. Inside a shop and this sucker backfired so loud both of our ears were ringing for about 3 minutes

His car is FBO, fully catless, and has an E35 blend.

Sorry for the poor quality, had the video texted to me.

I guess the term "works" is subjective. I wouldn't say backfiring is it's intended purpose

LOL

I know the feeling.

When we dyno'd my C6Z I was about 5 feet from the back of the car. All of sudden as it approached 5K RPM it was loud as hell. I tried to stand my ground and eventually covered my ears.

I was like DUDE?! Why didn't you tell me it was going to be this loud!!

Ears were ringing for quite a while. Funny thing is that was through stock headers and cats.

He's like how many times have you been behind a Corvette going 175 MPH, 5 feet from it with no wind noise....

My buddy (car owner)! He definitely wasn't ready for it

I hooked it up for him and got everything setup, and told him to make sure he's recording I just feel bad for the next guy to tailgate him.

Right? I mean, sure it was loud, but did you HAVE to drop the camera? I hate people who can't film.

This could not be safe for any turbo, or or modified.
