We don't have an electric one available yet. We thought we would start off with the manual design. I had one of the 1st guillotine style cutouts that I purchased from the original vendor before Dougs Headers took them over years ago. Love the electric ability, just not the issues. I'm glad your...

Huh?

OK, I give I give...

I found a great article by a Turbo Systems Engineer from Garrett Turbos. It's long but very informative.Turbo Exhaust Theory I stumbled across this information on a forum. The following excerpts are from Jay Kavanaugh, a turbo systems engineer at Garret, responding to a thread on Impreza.net...

Our belief is that anything that can restrict the flow is not good. Exhaust pipe itself is restrictive, even mandrel bent. The friction of the exhaust as it flows against the pipe (skin friction) slows the flow. Any bends, crush/wrinkle especially slows flow. Any muffler restricts flow, some...

Wow that would be something to see!!!!!!

Correct Pronto. They vary in effectiveness, but none flow all to the atmosphere. We just feel that our design does that job well. Some agree with us, some don't. That's why it's great to live in a country where we can agree to disagree;)

Sorry if I took it wrong. Wow come on folks it's just a discussion... People have a right to give their opinion. thanks for the comments. We are getting it quoted in SS. but because it has to be precisely fitted, the manufacturing isn't as cheap as you or I would think/hope. It can't be...

I'm sorry, I guess I was looking for a manufacturer/company.

So you've made the point that our compact "TURD" design could be used and be beneficial as a mount for a BOV/boost valve/EWG. As i normally find on forums, you have comments pro and con. It is what it is, and we appreciate them all. Not everyone will appreciate it, nor do they have to purchase...

Could you please give me an example of tried before?

Well here's hoping to prove you wrong. If you gain hp from a y pipe cutout, then an open header should be beneficial as well. We will see how we do:)

I understand Brandon and we may well do that. We just feel like it just makes sense that getting the exhaust out as quickly as possible, while keeping the velocity up, and with the least amount of turbulence and restrictions is going to give the most performance. Again, I have never seen a drag...

Chuck, Given that your a staff member here, i will highly assume your car was pretty well setup/tuned. I know that carbureted/injected cars sometimes need to be fine tuned to get the benefit of the additional exhaust flow from a design like ours. My friend runs a 347 stroker in a Ford Pinto...

I tried to look up the Jersey cutout, couldn't find anything on it. It sounds like what I was thinking of.

Another question, How nasty is the exhaust coming from the down pipe. In either stock, mild or extremely modded cars. Is there a real danger of flames damaging the vehicle? could you just route (point) the down pipe toward a metal suspension area for track time only? I have never ran a turbo...

Thanks for all the replies. This is what we are seeking, input both positive and negative! It helps with our decisions. The venturi effect is interesting. It seems like a header collector extension would give that effect. We felt this could be done by positioning the cutout at the classic 18"...

Well first off, it doesn't have the problem of filling the classic dump tube with exhaust when the dump tube is capped off. Second, the classic dump tube only expels part of the exhaust to the atmosphere when the cap is off. The rest has to go out the entire exhaust system. If this theory...

Interesting, Why is the cutout so far from the Turbo? Is that the only possible place to install a cutout on the G body cars? Also what if the DirectFlow cutout was installed in the down pipe and some short form of piping was attached to it and routed the exhaust to a safe place under the car...

This was demonstrating the old design. After much thought, we decided the design needed to be more compact.
