I finished installing the DMH Performance electric exhaust cutout for my Borla Exhaust yesterday. Dave Hacker has put together a good product here (quality construction butterfly valve-damper (with machined stops), jacketed cabling cut/terminated to proper length, weather seal-able connectors and quality 2-way return to mid-position switch.

I had a problem with 1 of the motor wires shorting to the valve body, which caused the valve to close but not open when installed on the exhaust, but it worked fine when hanging freely. Dave called my 6 hours after my email and helped me find the problem.

Now my wife can drive in stealth mode and I can open it up whenever I want to make more racket/power!

 

Anyone else tried this product lately? It finally allows me to use the Borla exhaust bypass, the way that Borla should have made it.

 

I'm about to purchase this... just waiting for my credit card bill to auth paypal, and my paycheck in 2 days. IF i can get my cutout installed no problems i'll post a nice review maybe with pictures too
