Good idea, but the flange system needs improvement.

Good idea but needs adjustment to allow the flange system to be rotated, shipping wasn't great, returned a used pair (bought new) and the second set was damaged in transit but noticed the setup doesn't work with others snippets I had.

Pros
  • Headings
Cons
  • The list is getting long.

Good idea, but the flange system needs improvement.

Good idea but requires some work to be able to rotate the flange system, delivery wasn't very good. the set was damaged in transit but found the installation didn't work with other cut outs I had.

Pros
  • Pre-wired harness included with lighted rocker switch for easy installation
Cons
  • Expensive

then the engines fail. how to get interchangeable motors

They work for one or two, then the electric motors fail. So you get interchangeable motors that work again several times. I have already replaced 2 motors and here it is broken again. should be a good product when they find out the motor problem.

Pros
  • Reliable 12 volt DC geared motor and twist lock for tight closure
Cons
  • There are nuances

Could be great fits manifold

Probably the best in terms of performance and sealing. But they are big and take up a lot of space. Doug could make it smaller if he wanted, all they had to do was remove the flange with three bolts, trim the tube and use v-clamps. I know they will claim it increases the cost but who cares when you can't use the product anyway because it's too big.

Pros
  • Ideal for circuits that don't require mufflers
Cons
  • I won't say anything

If I had to do it again

Since my exhaust system was designed with this in mind, I encountered an expensive fabrication change to convert it to a butterfly style. These cutouts are quite large as the gate needs to open fully. engines burn out. Some sooner rather than later. Any welding on them will void the warranty. So if your heart is set on them, buy 2 sets. They have decent customer service if you need to replace engines. LO LYeah so if I had to do it all over again I'd be a butterfly guy. Oh yes, I forgot to…

Pros
  • Open the exhaust pipe by flipping the switch on the dashboard.
Cons
