The Fabspeed/VAC headers are built from 14-16 gauge T304 stainless steel and come polished with an optional hi-temp coating. However, we had VAC send them straight to Swain Tech for its White Lightning treatment to not only maximize the scavenging effect for best performance, but also to help reduce underhood temperatures as much as possible.
I’ve personally been using Swain Tech coatings for years, including in a previous BMW M3 turbo as well as with MotoIQ’s own Project Supra. While not the most aesthetically pleasing to some (I like it), this stuff's the real deal.
Swain Tech applies its coating very carefully, covering as much of the exposed metal as possible to maximize heat retention. Notice the headers also have provisions for the factory EGT sensor (left), as well as bungs for all four factory 02 sensors (one of which is pictured right). However, if you're getting a new tune, your tuner should be able to shut off the rear two 02 sensors, as Randy at Epic is doing for us.
Here’s a close-up of the flanges.
The headers have a transition from the flange to the primary piping that is very smooth to the touch. All of the piping is mandrel bent for a great fit and maximum flow.
Back at Modified by KC, Nelson is our technician again for the header install. Removing the factory headers is a pain because the bulky catalytic converters, coupled with the tilted motor, make the top header nuts difficult to reach. Nelson was pleading with me to bring him a Honda Civic next time.
In all honesty, without Modified by KC’s help and dyno I couldn’t accomplish any of the articles I have–or ever plan to–publish with MotoIQ. The MKC guys are solid, honest and have a plethora of experience in tuning, fabrication and general vehicular service. So, if you know anyone looking for a reputable shop in the midwest, refer them to MKC so they can keep their doors open and I can keep showcasing build-ups for you!
