I've been getting tired of loud exhaust on my drive to school, so I made some changes to my exhaust. I gave it an e-cutout I made, and a silent muffler. It may be home-made, but it works perfect and doesn't scrape for once. HUGS the chassis.

I'll be taking some in-car shots tomorrow when I get it street-tuned a little better, but for now this is what a 3" DP w/resonator sounds like VS a 3" DP w/resonator and stock chaimbered muffler. It still has the original EX tip - cops at school are going to go crazy because of it

BTW if someone has seen a faster e-cutout, lemme know. I can make this one around 2.5x faster

 

Mine is much faster, I will get some video tomorrow.

 

You sure? This is with a ~70 degree sweep of the motor, on the low setting (42rpm vs 62 rpm). I could also add springs so its full power longer - only half the sweep each way is powered due to inertia. I ruined 2 aluminum arms before I got it right. :1

How does yours power the butterfly?

 

Why would you need it any faster than that?

 

I love that chit.

 

To have the fastest e-cutout ever made.

 

Mine is spur gear driven, its sick fast...

The motor I have on it I think is a 5 volt servo motor... and I just run 12v to it. It SNAPS open, and a spring will snap it closed when the brake is released.

 

seeing all this e-cut out ---- is making me want one but i dont want to spend more than 50 for it

 

I was thinking about a setup like that, but I honestly didn't want to get into the complications behind controlling a servo motor. Mine is just a relay, 2 switches, and the motor. May I ask how you ended up moving that servo? I'd really like to see how you did yours, if its as fast as you say it is. Vids too pls

 

very nice.. make me want 1 .. i'm sure it's alot cheaper than getting a ful exhaust done?
anyway to make it open by itself by certain rpm..? would be co0l to have it open 4500-5000 rpm...
