This is a great opportunity to add a Turbo to just about ANY Pontiac with out the need for welding. These headers are all v-band clamped and have per-fabricated bends that use the same V-bands that offer virtually unlimited options for positioning / and mounting / Adjusting for the ideal turbo placement. The V-bands also offer ease of installation and removal as well as gasket-less leak proof connections when installed.

This option for the Pontiac crowd is a game changer since most Turbo systems need lots of welding which can be expensive if you dont know how to or know someone who can weld.

We are in the middle of a Group purchase for the Round Ports /Ram Air V headers and Stainless Headers is going to make the flanges for a D-Port header. The D-Ports are a tricky design due to the D Ports being so close together...
The method they plan to use to get around that is to use one larger Tube that covers both Ports. Check out the details to the Boosted section in the link JC455 provided if interested.

We have two list going right now... We have a Round Port /Ram Air V head list and a D-Port list... The more we add to the list the greater the discount becomes.

SPEED SAFE, NICK

Is there a dividerin the Log to isolate 2&4 from 6&8? ( easily done)

Likewise a divider in the Log to isolate 1&5 from 3&7 (can be done)

I will ask this question however from the sounds of this the gains would be minimal... Perhaps I can get Steve on line to answer this directly.

I added your question to the main Tread in the Turbo section.

It's a log feeding a restriction in the exhaust with no tuned length.
I see very little to gain there.

Look at the Firing Order for EXH pressure pulses charging the Log, AND these pressure pulses go right through the CYL experiencing E/I Overlap.

Just wanted to touch base to let you know that they do have plans to make 2 options for the "D" port guys. One would be without a divider and the other would be a performance version with a divider. The reason they will offer 2 different versions is due to the price difference. The one with the divider will take a considerable more work over the one without and therefor the price will reflect the additional labor.

However the bottom line is, these will be available for the D Ports... If you are racing and running high boost, then the divider will be the best option. If your just street driving with low boost, the header without the divider will cost less and still perform well on the street.

Check out the main thread in the "BOOST" section...
