We will not be using the x pipe on this build. The headers sit back too far to bolt then up. I am sure that someone somewhere has made it work but we don't want to spend the time and fab effort for unknown or questionable gains. We will run the dual pipe into a single gt resonator then out a RMB. If it is too loud we will add something between the headers and the gt resonator .

Thanks for the idea Imre. We may try to fab up some type of crossover. We are limited to parts on hand and I sold the only H pipe I have ever owned. Truthfully, that pc would have the same drawback as the X pipe that we have. The headers come back so far while the H and X pipe were designed to be used with the stock manifolds and rest in place of the factory catalytic convertor. We have the x pipe that we can cut and weld if needed but the width of the tunnel will limit what we can do. We would potentially be destroying a pc of art 
It will be a fun Saturday either way. The car should be driven either today or tomorrow sans mufflers.

We do make a Header-Y for the 16v headers that will do the connection for you.

Wanna trade it for an original, first generation, Ott X-pipe??

The S4 has the sport seats so is a comfortable ride!! I do have the pod out of it but drive it around with the instrument cluster sitting in the dash framework!

We have run into a few more setbacks. To console myself I broke down and bought this http://www.928motorsports.com/parts/headerypipe.php
It will not do anything for the fueling but it will make the exhaust fabrication a whole lot easier.

The car is fine. No changes from the video below.
Some unrelated issues have prevented the car from being worked on.
No drama, no
..........just time I would rather be driving.

Here is a picture of the exhaust set up we plan to use. The one on the left is from my son's long gone 85. I am using it as a rough template for ordering parts. On the right is 928 Motorsport Y pipe- two 3" 45 degree bends and not pictured is 48" of straight 3" pipe if needed.
You may be able to see the one on the left had a homemade RMB with duals into a 3" exit pipe. The oval cover is SS that has been painted black. I am using a chemical stripper and it is beautiful under that paint. I will be using that final 3" and oval as my exit pipe. It even has the hanger still on it!!
I hope to find a hobbiest welder that can cut me some slack. Any money that is spent on welding must come out of the paint money.
