2011 XLT Super Crew 5.0 with an 18" Magnaflow/SIDO (Raptor style) setup.
Left on the resonator and you still know it is a V-8, when you step on it everyone knows it is a V-8. Still safe for multi-hour road trips.

Hey guys. Need a hand here. I have a 14 f150 5.0. Roush cold air intake and just had a cat back SIDO added. Well I went to the muffler man in Brockton and they used a muffler that was a off brand but said they had better luck with it. So from the cat back its 2.25 now with a resornater and the muffler. 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.

I think your right about the 3" from cat to muffler. Or 2.75 I'm pretty sure that's what it was stock.

I will keep that in mind. Thank you for the reply
