So I actually ran a 3rd cat, resonator, and muffler delete for awhile. It's actually healthier for the engine to have a decent resonator in the system. It's better for back pressure, and you might think it sounds cooler because of the backfires on deceleration. But your piston rings won't.

But it does sound pretty good honestly. Now I'm running a resonator my fabricator friend built from scratch and my 3.0 definitely has more power and sounds way cleaner.

Back pressure is a myth, it's exhaust pulses and cylinder scavenging but that's too complicated so people just say back pressure.

100% agree.
Yeah I just use back pressure as a term for it. Most people understand back pressure better than me trying to explain it in greater detail how a resonator essentially equalizes the exhaust pulses if done correctly (with the correct type of resonator)
Science is fun 🙂
