More exterior photos
Here are some photos of the exterior of the car. JHM stage 4 clutch, lightweight flywheel, solid shifter linkage, Delrin shifter bushings, Stern control arms, and Stern motor mounts have all been installed. We had a clearance issue with the 18x10 TE37s and the rear parking brake spring; it would make contact with the wheel weights on the inner wheel. After moving the weights out 2mm, we didn't have any more clearance issues. 18" wheels with the Alcon brakes are a TIGHT fit.

Quick walk around video
I brought my camera to the shop today and took a quick walk video walk around. I have some exhaust videos that need to be encoded still.
BBK is ON
After buttoning up the rest of the car, we decided it would be a good day to finish up the brakes. The front and rear brakes were installed, but I only took photos of the fronts.
Stern control arms and completed headers
Today we put the transmission back into the car and buttoned everything back up. If everything works out tomorrow the brakes and cat-back should go on!
Below you can see the high-flow cats mate up to the new headers. JHM offers a pre-lengthened set of O2 sensors since the O2 bungs have been relocated on the longtube headers.
Some "better" photos of the JHM/Stern motor mounts.
Here the Stern control arms have been installed.
The S4 goes under the knife…
Monday the S4 went under the knife to receive the first round of performance modifications. Take a look at the OEM exhaust manifolds. Proceed to cringe.
To gain access the exhaust manifolds we had to lower the motor. Pictured below, the transmission has already been removed.
The motor is supported so it can be lowered down enough to gain access to the exhaust manifolds.
Here you can see the JHM longtube headers installed.
This version of the headers uses v-band clamps.
JHM/Stern Motor Mounts
Thanks to JHM for hooking me up with a set of their modified Stern motor mounts. B6/B7 S4 motor mounts are 110mm shorter than the aftermarket mounts that are currently available; these mounts have been modified so they will fit.
VF Engineering supercharger
After almost a year of testing, VF's production forced induction system for the B6/B7 S4 is in my hands. What a work of art!
VF has reported 496 HP and /434 ft/lbs.
GMG 2.5″ RS4 exhaust with Labree mufflers
The last piece of my exhaust puzzle was the cat-back exhaust; having previously run a 2.25" APR downpipe and exhaust I needed something a little larger to mate up to the 2.5" JHM longtube headers. After poking around I found S-Fore, a local forum member, parting out his S4. He had originally purchased a GMG RS4 exhaust, but found that the internal drone was too much. To rectify this little problem he replaced the GMG mufflers with Labree mufflers and hasn't looked back since. When I asked S-Fore to describe the sound, he said hands down it was the best sounding S4 exhaust. Ever. Once the headers and exhaust are on I'll see how the quad tips fill the RS4 bumper; if it doesn't look right I'll have ...
Ceramic coated longtube headers
My JHM longtube headers have made it back from Performance Coatings! They've recieved a satin black ceramic coating to dramatically reduce radient heat.
We're looking at a 110-120 degree temperature reduction in the engine bay; this should be good for a 11-12% increase in engine efficiency. Gotta love free horsepower!
For a 450-500HP motor we can expect a gain of 50-55HP. Show me a better mod for the money!
Thanks to Performance Coatings and JHM!
