Exhaust Question Reply #16 – December 09, 2009, 04:43:58 AM I have gotten over 30mpg several times on the freeway with my v-8 bird. Back in the day my old 86 cat had a clogged catilitic converter and they said that that is why it wouldn't pass emissions. I punched out the honey comb in it, and it got even better then it did with the same cat several years before it.You don't need a small engine to get good gas mileage, although, it definitely helps, and a cat isn't always better for emissions. City I drive under 40mph with less then 10 minutes drive time generally and can get over 17 city. Quote Selected
Exhaust Question Reply #17 – December 23, 2009, 06:09:22 AM I have a 95 f-150 5.8L 4x4 and I am only running shorty headers with the dual factory cats on it and no ler. It sounds pretty good to me.I want to cut them off too and do a y pipe to a 3" cat back. But I don't think I will get better gas milage or better performance.The Cam kinda kils ya there. A guy at work with a 460 in his 97 f-250 took out the cat and it sounds pretty good. Quote Selected
Exhaust Question Reply #18 – December 25, 2009, 08:34:46 AM this might be late but, the loudest exhaust i did on a car so far was shortie headers, 2.5" pipe with no cats, mac prochamber, and flowmaster single chamber lers. having true duel exhaust or a cross over makes it louder then having a y pipe, and having the pipe get bigger as you go to the end makes it louder too, like a trumpet... anyway with that combo on a mark VII i'd set off car alarms everywhere lol. the only thing louder was when i ran nothing but my long tubes, or my friends car with true duel straight pipes... but that sounds like poop with no cross over imo.
