    hi guys,

    befor i changed my engine from a SB 350 to a BB 454 but i still use my old mufflers (two standard ones)... will such a thing damage the engine as it might not give enough airr flow out of the engine or not?



    thanks

    they will work, but not as efficently as you might want... especially going to a BB... if it is mostly stock i would run at least 2.5 in pipe... if it is "built" go w/ the 3"...

    won't damage anything. May be fine, what size pipe are you running and are they factory duals or an aftermarket system?
