How long does it take for one to open?

Reason I ask is because I have a cutout in my exhaust now, and even with H/C it sounds pretty bad at low RPMs. I was thinking about installing the electric cutout and wiring it to open only at WOT.

 

I think mine is about 6 seconds.

 

Might depend on the brand, think my QTP opened in less than half that.

 

My DMH opens in about 3 seconds. Same with closing it.

 

a friend of mine had one on his car and it took prolli 3-5 sec.

 

When I had my QTP on it would take 4-5 seconds.

 

My old Mccord took 4 secs to open/close.

 

5 seconds when it was new, seems to take 8 seconds now, but I think it's dragging on the inside of the pipe. It's a McCord from BYUNSpeed.

Definatly a good investment, you can suprise the **** out of people with one.

 

No kidding. I was playing around with (no actual race) a cammed Z28 the other day and he had a Borla system on it that sounded pretty terrible. While at WOT the exhaust note got really aggressive and sounded nice. I was like WTF The change in sound impressed me. The lack in additional acceleration did not

 

MY dmh takes 3-4 seconds. You might be able to change the motor to open faster. Sounds like a good idea to me, tell us how you did it when your done.

 

Ditto on mine as well.

 

yeah me too...
