Before you flame me...its only temporary for a few weeks until I have cash to finish off 2.5" exhaust and hiflow cats. Just want to know if these dumps will bolt up to stock pipes? I am thinking it won't as the flanges have the bolt holes in different spots so won't line up? Also... just probably thinking about it a little too much and its been a LONG day at work...But because I have GT28RS cores in my stock housings... will these dumps be suitable due to the larger exhaust wheel? I guess I could just grind them out a bit more? Looks like the centre "splitter" bit might have to be removed? Benny help? haha.. This is what I mean... Hiflowed turbo on the left
you will have problems match porting the four bolt dumps to the gt28rs hiflows. email AMS or coz and find out what size the turbine hole is in the 4 bolt dumps. My 4 bolt dumps (flange)were custom(CES) made to suit the 48mm opening . most people try to chamfer the opening but thats still a bottleneck!
