I agree, we put the 40 series on my dad's 70 Camaro Z28 with 2-1/2" it sounds awesome but at certain rpm's it does resonate a bit, but with it being a car it isn't so bad, our truck it would be worse. My truck has glass packs now and I can't wait to have the coin to change to the 50's. If I drive anymore that a half hour I think it starts to resonate in my head!
