Typical dual exhaust / dual mufflers, exit out the back.
Say I add a Y-pipe on each side, and add one more identical
muffler per side (so 4 total), and so now have 4 tailpipes.
Will the new exhaust system have less backpressure and be louder,
or will it have less backpressure and be quieter ?
Do it and let us know
AKA, what diameter is your pipes from the manifolds or header collectors to the muffs and on back to the second set of muffs?
I think of exhaust systems like electric circuit, resistors in electric circuit in series restricts the flow, resistors in parallel don't increase resistance to the flow
I think four muffs ran in parallel mounted at the rear bumper off of two Y pipes would flow the most and be the least noisy
