Greetings all! I know this forum is not as busy as it once was, but was always a great source of information. my question is specifically regarding exhaust size. Starting at the primary tubes and ending all the way at the mufflers. My current set up detuned makes just over 700 wheel horsepower. If I pulley it down and run it on kill it makes just under 800 rear wheel horsepower. This is through 1 5/8 Mac headers with a 2 1/2 inch Mac H pipe ending in 2 1/2 two chamber flow masters with full tailpipes. I’m wondering how much more power it might make if I switched to a 1 3/4 or even a 1 7/8 header with a 3 into 2 1/2 X pipe and straight through bullet type mufflers. Has anyone run both? I’m wondering if the power potential might be worth the cost? Any input would be greatly appreciated. Thanks in advance!
