I don't have any dyno data foor the exhaust. I didn't have in installed for very long. I'm going by the info that I've gathered here. From what I understand, the engine needs sufficient backpressure to operate properly and replacing 4 stock cats with 2 hi-flo cats can be too free flowing without smaller pipes. Once again, I'm no expert here. I'm just going by what I've read on this and other forums.
