Ok after reading some more above posts, the knock off may be a tad too loud, & now that you know what the 10 series looks like.

A Flowmaster 40 series or 50 series I would now suggest.

Not meaning to be confusing earlier just trying to help you out a bit.

def not a 50 series, that is def too quiet. 40 series or better. just still looking to not spend $60-80+ on a muffler like it would cost for a flowmaster.
