I feel like I lost something here and also with the cold air intake there's just more vibration on the pedal when I get in her. What should I do here. I'm afraid to have the resornater taken off and be to much. I forgot to mention its a 50 style muffler instead of the 40 so it must be a flowmaster knock off. Let me know what you think
Only my opinion. 3" should have been maintained to the muffler, then the 2 1/4 dual out. IMO, it's choked down too much. Is it a FloPro muffler?
OOPS!! I meant 2 1/2" to the muffler, that's the stock size.
The CAI, I don't think has any bearing on the vibration. Aesthetics and sound is the only thing they're good for.
FWIW, my little Ranger with the 3.0 has 2 1/4" between the CATS and muffler, with no resonator.
