Anyone on here a mech. Engineer
I've got a question about flow characteristics of an exhaust idea.
Some guys are hollowing out there DPF so it looks stock. What would it flow like with the downpipe being 4" then going to 8" for a few feet then to dual 4" exhaust with one 4"aero turbine muffler in each of the 4" duals. I've heard the aero turbine's aero foil design helps "pull" or scavenge the exhaust out but would the velocity crash once it hits the 8" section? I've also heard this will make the exhaust sound like stacks without having stacks. That sweet hollow grumble.
The more accurate and scientific the answer the better please.ill attach a crude drawing of what I mean.
