So in the old days, the thought process was to use big diameter tubes for all-out top-end horsepower and to use smaller diameter tubes for improved exhaust flow and more low-end grunt. Is that still true today?
I'm asking this question because I'm building my '18 GT as a touring car versus a track, autocross or drag car. It's going to be street driven 99.9% of the time but I may drag race it a couple of times just to see what it runs.
I'm down to three different cat-back exhausts: 1) Ford Performance Touring with 2.5" diameter tubes; 2) Krona with 3.0" tubes and; 3) the Thermal with 3.0" tubes. So my old school thinking tells me that I'd be happier from a primarily street performance perspective with the Ford Performance exhaust than the others but with so many choices I'm just not sure.
Does anyone have any thoughts or data on this topic?
