Exhaust upgrade on Stage 4 G60- currently std!

[Neil VR6 0]

Obviously I'm looking at a modified exhaust seeing as the one on it now is currently standard. I've decided on a Magnex as I used to have one on my Saxo VTR and the fit was spot on and it didn't make a racket. Would this flow enough gas for a 68mm pulley & stage 4 and would it require an ECU re-map given the gasses will be escaping quicker from the engine? Sorry about the repeat posts, so many questions! :oops:

The chip you have in your ECU will run on the richer side of things so you have no worries about having to get a remap. Cams and flowed heads bigger capacity bottom ends etc requre the ecu to be remapped. Exhausts do not really make a huge difference to mixture.

Rich, you're telling me! I did about 40 miles (some of which were small journeys from cold) and it used half a tank!

Just looked at the Pitstop website, so many nice shiny things made by Mocal! :lol:
