i found these cars make a noticable difference in performance with just exhaust and a k&n air filter. how the heck are these cars supposed to perform with 2" dual exhaust? i ran dual 2.25 with 2 chamber flowmasters, removed the back 2 cats, and have polished stainless 3.5" tips. sounds really nice, not too loud but sounds just right for a lincoln. even with 159,000 on my '96, it still pulls pretty good and has a much stronger mid range with the exhaust and air filter upgrade. she'll pull all the way up to 107 (speed gov.) easily. i haven't ran it yet, but i say she could break into the 15s
