I'm curious too. I might try this after the header install and go back to a stock cat-back.

I used to have a DMH, it was good. The QTP I had before that was absolute garbage.

I have these right off the Pacesetter's and I love it. No video or pics yet though. I'll get some soon.

I ran QTP's for several years, they are junk at best. It's clear as soon as you see all the components in person. The electric motors are "sealed" from the elements with heat shrink tubing which curls up and exposes the motor after the first heat cycle. The unsightly switch they provide is huge, appears and feels cheap, and the contacts on the base of the switch are wrapped using electrical tape. The connections on the switch are Radio Shack grade speaker connectors, fitting, seeing as how the wiring is insulated speker wire. I replaced 4 motors in 2 years due to stripped gears. The manufacturer gives a 90 day warranty, which is the worst of all manufacturers I've found. The quality of customer service is also fitting of their product. The one issue I never had with them that everyone else running them seemed to have was the valves leaking when closed.

The DMH and Race Ready Performance valves use a completely different style motor as opposed to the QTP units. The housings are actually sealed legitimately which allows the motors to live substantially longer. Also, the valves are sealed with orings when closed reducing the chances for leaks. My experience is that these valves do not leak. As for the warranties, DMH has a 2 year warranty and RRP has a lifetime warranty. For this reason I went with RRP. I have never seen the components from DMH in person, however RRP components are very high quality and have a finished look to them. The initial cost is higher but you'll be money ahead as soon as you start replacing valves with the QTP's. Race Readys customer service/support is top notch as well.

I love the cut outs as it gives me the option of being completely obnoxious or very close to stock level. I don't have any pics but I'll try to take some and post them as well as a couple videos.

what about those one's that were from eBay??? I'm looking at doing this route on my v2, so when I wanna be loud I open them, but otherwise I'll run it through the stock...

I've tried a couple over the years and never once had one last. To be fair, they were generic / ebay branded units.
