Is there any difference between the GTI and ED30 downpipes? The reason I ask is that I am currently Shark stage 1 with my octy on the standard downpipe with the precat removed. I was after a bit more power and going to go for stage 2. Would I be able to run a stage 2 file as I am because I dont think there is any difference in downpipes and the ED30 runs much higher BHP with the standard downpipe on a stage 1 map.
Eventually I am going to fit the K04 turbo, S3 injectors and DV relocation but am just after a bit extra in the mean time. Any help or advice would be apprecieated?
