Hey guys. I'm looking at getting a low mount exhaust manifold. I'm having trouble with witch one is best for me. I've seen that there are different 'flange' sizes? Is this refering to the size of the output from where the exhaust manifold bolts on to the turbo? If I'm correct what size do I want to go for? ATM everything is stock apart from exhaust. Do I go with the 'T3' ? I'm planning on putting stock turbo on as I'm looking at getting it high flowed. Thanks a lot guys.
