Hello fellow stang bangers. Heres the scoop. As a lot of you know, I have 2 chamber flowmaster on my 93 hatch with no pipes out the back. I got the car this way and haven't gotten around to purchasing some. First question, does lack of tail pipes greatly affect hp and low end performance and if so what size would you recommend? Secondly, again as many of you know, I am trying to crack low 13's or high 12's. I have recently ordered 3.73's. I have an explorer upper and a cobra lower intake and am wondering what heads and cam (e,f or stock) work well with this combo. Also, how paramount to my cause is the maf, tb and rockers initially. I am giving thought to an a or s trim s/c but would like to reach my goal without a power adder if I can. Thanks for any and all info, as usual you guys are a wealth of information.
