I"m interested in any feed back on the removal or modification on the pre heater in the crossover pipe to inlet manifold and the removal of the EGR valve. The objective is to reduce restriction while still giving the appearance of stock.
I've seen people pull the heater element out of the alloy surround, which still leave a small hole, but still looks stock and I've seen people remove the heater completely which is dead obvious to the boys in blue! Has anyone had an alloy plate CNC'ed to replace which looks stock standard?
Most people put a blank in the EGR pipework to stop the entrance of exhaust gas into the inlet manifold, this looks stock but still leaves a rather large valve in the crossover pipe. Has anyone completely removed the valve and inserted an alloy CNC'ed block? No, this would not look 100% stock but a good compromise in attaining unobstructive flow while looking pretty stock to the untrained eye.
Thoughts??
