if you dont have headers, then it will just be open exhaust, or manifolds...

place the cut-out back from your factory y pipe a few feet... and it will sound fine while driving, it will just sound like **** idling... until you get a nice cam and LT headers.

mine picks up 21 rwhp with the cutout open.

I liked the way my truck (basically stock at the time) sounded with a cutout.

BTW, why is this in Internal engine modifications?

because the exhaust section was full.
