Our O2 dump only vents wastegate exhaust gases, those other two options would dump the exhaust gases that go past the turbine (which I believe is what you're concerned about in regards to the restriction from the stock exhaust). Let me know if that doesn't make sense lol.
sorry im a little confused by this. so it only opens up at WG pressure? if i were to get one and still keep my DP,TP, CBE would i have a downside? or is this only cause he wants to use a stock CBE? srry if im not making sense now.

have maperformance make you a varex catback. im pretty sure they can make it for the 8/9 as they made one for me so they probably have a jig.

I'm running a Sound Performance boost actuated cut out and I love it. It starts to open at 5psi and is fully open at 11psi. Its one of the best mods I've ever done. Plus I like the fact that there isn't an electric motor that can fail. Not to say the actuator won't, but I've heard plenty of stories of the electric motors going bad in those electric exhaust cutouts. Plus using the boost actuated cutout IMO is a more stable option from a tuning stand point unless you make the electric cutout open automatically the way Freddie suggested.

imo most electric cut outs leak and give you a nasty sound, if I was going to do an e-cutout I woukd get a dougs headers e-cutout. its self cleaning and leakproof. The boost acutated cutout is def cool

Our external dump o2 housing only vents wastegate exhaust gases, so yes when the wastegate opens those gases will vent to atmosphere. The OP is trying to regain lost power from switching back to a stock catback, our o2 housing won't help in that regard I'm afraid.

The first problem is the QTP cutout will need to see reverse polarity to close. I'm hoping someone on here can help me with.
The second problem is the when opening, but mainly closing, the power needs to cut when it opens/closes so it doesn't burn the motor from constantly having power to it in either direction.
Please!

^No problem, I don't think your a dick. I know what a relay is. I don't want a schematic either, but some people may. Here's a schematic I drew up quickly for those who are interested. However, this should burn the QTP motor when it's closing, because it will be constantly trying to close.
I need to know what product will stop supplying power when the qtp fully closes and how that would work. I don't want a circuit breaker that will trip and stay tripped every time it closes. I've exceeded my knowledge of electronics. I'd love to learn more and that's where this forum comes in.
Thanks for anybodies help!

I like the SP Boost Activated Exhaust Cutout.
