That's wierd...I have no vibrations on the highway and no drone. I couldn't imagine that the dealer would give you any crap. I think the only purpose of the resignators is to quiet it down and doesn't really have any affect on back pressure.
no worries, im very interested in doing the resonator removal but i heard stories of bad vibrations on the highway as well as a bad drone, im also curious what the dealer would say or give me a bullshit speach about the backpressure and im wondering if ill lose a little pressure but will make it up with a tune and intake.
Hey sorry it took so long for me to reply but I didn't even notice I had a new massege. There was no performance gain that I could feel, but it sounds ALOT nicer. If your looking for a beefier sound then yes have them removed. It gave it a deeper rumble and I have had many compliments on the sound.
whats goin on. i saw on an old post of yers that you had the 40 series with resonator delete. i was curious if you noticed a difference with the resonators off. i had a 40 series installed an left the resonator cuz the guy said i wouldnt notice a difference. when i cold start my truck it sounds great but after it warms up it gets kinda quiet.. thanks
