Dynomax VT muffler from Berk tech on a Sedan
Pretty cool. Like the stock nissan muffler, it uses a flapper that opens when the exhaust gas flow is enough. Quiet when flow is low and wide open when you need it.
Interesting thoughts though:
1) The use a 3" version.
2) They mount it where the resonator usuall resides. Nissan mounts their bypass mufflers on the end of the exhaust. Odd to me
3) Drone is completely eliminated. And that's on a 3" exhaust system.
This is here because it's specifically addresses a sedan.
