Just got word to go ahead and sell the last set available in the US. These are modified stock headers to run either a hi-flow cat or test pipe.
Stock Primaries
Reversible DECAT header system allowing switch over to stock CAT's by way of V-Band clamp
Fully assembled and welded with flange as a direct bolt-on solution to stock downpipes.
Stage 2 Evolve software highly recommended to release maximum potential and avoid engine management light
Performance gain approx. +20-30hp / +25 lb.ft
The Evolve Race-R header is built using the stock V10 headers with a reversible decat by way of v-band clamp.
You can switch between your stock CAT's for emissions purposes and decat pipe which will allow a large performance increase through the RPM band.
The taper from the primary collector to decat pipe is smooth and long allowing a smooth exit of exhaust gasses.
Stage 2 software is highly recommended to take full benefit of this unique upgrade.
