I have a hellion turbo kit and the ic is 2.5 out and charge pipe is 2.5 to tb. I want to make a 3 in pipe in the bay at the least mainly for looks as the 2.5 looks puny. If i do this is it better to leave the maf in the 2.5 in pipe inside the fender where it is currently or continue the 3in as far down as possible and put the maf wherever the ideal location would be, or does it not really matter?
