Electric exhaust cut outs

QTP = Quick Time Performance. I have the 3" ones and they're AWESOME, fully adjustable (loud and louder), stainless.
 
I have a QTP set here beside me that are going on in a few weeks, mine are just 2.5". They were not inexpensive.
 
Whatever brand you decide to use I strongly suugest using a set that is "all" stainless steel...the housing and the "flapper".... buddy of mine put a set on his 67 GTX a couple years ago and the housing was stainless but the butterfly/flapper was aluminim and last year he started having coriosion problems with the "flapper" to the point where it would not close & seal correctly.
 
QTP's. Reliable for 10 years. Used and abused. Mount the push/hold toggle where it can easily be reached. Can be addictive.
 
I bought a pair from Summit. They were cheaper than the rest. I have them on for about five years now.The motor burned out on one of the original ones. they replaced it with a new one. They changed the design to isolate the motor from the heat. I haven't had a problem since.
