November 17, 201015 yr comment_482713 Hi, I am currently putting a 4age blue top into my ke70, went to a couple exhaust places and they're all recommending different sizes. Would a 2, 2.3 or 2.5 inch system be best? Thanks for the help Report
November 17, 201015 yr comment_482715 i went with 2.25 press bent with mine. its much of a much ness i think. its only a stock 1.6L so i think 2.5 is a bit over the top. Report
November 17, 201015 yr Author comment_482757 ok sweet thanks for that. So 2 inch should be fine then? what did the ae86's come standard with? Report
November 17, 201015 yr comment_482918 2.25" mandrel or press-bent would be ideal for an aftermarket system - it's only a 1.6L but likes to rev high so you need to take that into account. Report
