I've officially closed this group buy, we're over full! We will start shipping system this week, I know I've been saying this week for a while. These are far more complex to build than we expected, that said we're getting them together, have confirmed the results on our car with a production set. Will have the first 5 sets out this week and hopefully another 5 out as well.
I've been tweaking and refining the tune, once I have final numbers I'll post up the production system results. The production pieces are more precise than the prototype (mandrel bends made to spec, built in jigs, etc..) and also make more power, more on that later...
Also here's another picture we took of the stock system, another companies race headers and the Dundon GT4 Race Header
GT4 Stock Header on Left, Competitor Race Header Middle, Dundon GT4 Race Header on the Right

We wanted to keep it under wraps until they were ready to ship. We do our best to be innovative and design parts that do what we say they do!
First two on the list shipped!! Two to three more out tomorrow!!
We included.
Stainless studs and nuts in place of the stock exhaust manilfold bolts.
K&N air filters for all of those that have been patient enough to wait
A pick for installing some of the retaining springs.
Full instructions!
We'll keep pumping them out and can't wait for everyone to get them on their cars and give us feedback!

Looking forward to receiving my set. Thanks for the extras.

Know nothing about exhaust design, so a stupid question - wouldn't some of the hot exhaust gases leak out through that 4th pipe into places where you don't want hot gases?
