Engine Performance, TRD/aftermarket Exhaust, OVTune + Dump tubes and Vibrations

Let me start by beating the dead horse that involves tacoma vibrations but asking if anyone has noticed a difference in acoustic resonance induced vibrations with stock 3rd gen exhaust (trd sport non-stainless) vs Stainless TRD cat back or other aftermarket exhausts. The engine/exhaust is vibrating the truck at certain RPMs in all gears (no it is not: needle bearing, driveline angles, tires/wheels, breaks, axles, engine mounts... yet). Just got back from the dealer today and they said drive it till it gets worse... tell that to my numb hands and feet after a few hours of drive time.

Also thinking about getting OVTunes tune plus dump tubes (catted) and wondered if getting a larger diameter exhaust/stainless y-pipe (TRD, MBRP, etc) is worth it/necessary to maximize dump tube addition.



Thanks TW community,
