Porsche 986 Boxster Exhaust Catless Race Headers

$799.00

Product Description

The  Exhaust Headers are a huge improvement over the stock headers, 42mm primary piping that joins into a racing merger collector and exits via a 53mm exit pipe. Made of T-304 Stainless Steel smooth mandrel bends, perfect welds, stainless steel flanges. Our merge collector is welded to the exit pipe and not overlapped on the exit pipe like most other headers out there.

Not recommended for Tiptronic Boxster all years due to coolant line, our exhaust headers interfere with the coolant line.

For the 97-99 2.5L Boxster only , these headers will not fit with the factory mid-pipes, in order to install these headers you must purchase the our 986 Mid Pipes. 

For the 00-04 2.7L/3.2L Boxster , by installing these catless headers the ECU will trigger the Check Engine Light since that the catalytic converters are deleted with these headers and are for RACE use only..

The  Exhaust Headers are a huge improvement over the stock headers, 42mm primary piping that joins into a racing merger collector and exits via a 53mm exit pipe.

Our merge collector is welded to the exit pipe and not overlapped on the exit pipe like most other headers out there. 

The large piping along with the mandrel bend piping and racing merge collector ensure a smoother and less restrictive exhaust flow, unlike the original manifold where the exhaust gases are pushed to a common pipe all at once restricting exhaust gas travel and reducing performance. The Boxster makes its highest power between 5000 and 6000 RPM the larger piping will benefit and give you some good performance gains, the factory 34.5mm piping hurts performance at higher RPM's.
