After reviewing the size of our stock exhaust system's are, I am now trying to find out the point of going to a 4" or even a 5" exhaust system for performance. Now, sound is one thing, but performance, I don't understand the logic.
It is simple, and maybe I am oversimplifying this (someone tell me otherwise) but if you have a 3" exhaust flange coming off of the stock HX35 or HY35 exhaust housing, how is putting a 4 or 5" down pipe work when the choke point of the exhaust is 3", then going to a 4" or 5" going to help you move exhaust gases better?
I come from drag racing, I always have and It has always been gas, not diesel. Most of the same principles apply in both worlds, but even Bernoulli's principle can't be justifiable in this scenario UNLESS the turbo exhaust flange is larger than 3" and the down pipe or whole exhaust system is smaller than the exhaust housing. IE: you have a Small block Mopar with 1 3/4" primary headers that come to a 3" collector. You can run UP to a 3" dual mandrel system for the highest flow. Now if you put on a 3.5" dual system, you gain no benefit but now just adding weight. The sound might be a tad different but you can't move air faster going from a small tube to a bigger tube. Now you can do the opposite to a degree but only under pressure which exhaust systems don't really have in the sense I am speaking of.
Please tell me I am missing something here, or do lost of people like running ginormous exhaust systems for the look?
