How-To Install a Dynatech Stainless Steel Header Exhaust System
Story & Photos: Jason Coe

Want to pump more power into your full size truck? We cracked open a box containing Dynatech’s stainless steel header exhaust system and put it to the test on a 1999 Ford F-150. This kit features replacement precision-bent 1 5/8” SuperMAXX T-304 headers, catalytic converters, and stainless steel piping. This exhaust replacement system gives you a much wider power band for a dramatic performance increase. Automotive manufacturers tend to develop their headers with restricting exhaust flow to cut costs on time and production. This free flowing system solves your problems giving you more power, instantly.

Please keep in mind that Dynatech’s Stainless Steel Header Exhaust System is only intended for racing and off-road applications and is only legal in 48 states. For this installation we opted for an off-road vehicle and used Brian Olhausen’s Ford F-150.

Installation Steps

As with all installations, always disconnect the negative battery cable for safety.

1. When removing the factory catalytic converters and pipes, the transmission cross-member needs to be removed, otherwise it is necessary to cut the pipe out. For our installation we are removing the whole system all together so we cut the pipe out.


2. Remove the front plastic fender panels by popping out all the plastic fasteners and 5 screws.


3. Clean off the factory manifold screws and loosen the EGR nut. The EGR nut must be loosened and removed before the driver’s side manifold can be removed.


4. Unbolt 2 screws on the backside of the factory manifold and begin removing the stock extensions leading towards the catalytic converters. Prior to removing the stock extensions, use care when removing the (4) 02 sensors located at each end of the extension piping.


5. All stock extensions and catalytic converters are removed. Stock manifolds are still installed.


6. Stock extension and catalytic converter system.


7. Unbolt 8 screws from the header flanges and remove the stock gaskets.


8. Stainless steel headers VS. stock manifold (so restrictive!).
