Efficient muffler for turbo- 4 cyl

Efficient muffler for turbo- 4 cyl

Postby dfarr67 » September 11th, 2016, 6:25 pm

I have a 1990 Toyota 4runner with 2.4L turbocharged, 2.5in full exhaust no cat, wondering what the quietest and most efficient muffler is. I understand turbo's don't like backpressure and chambered mufflers aren't that great for this app. I'm looking at Dynomax 17218 stainless oval straight in/out. Low to mid rpm say 5500. Was also looking at Flowmaster DBX.
