how does it perform in this configuration?? the stock cat back does not look that restrictive to me. is it? how does the cobb sound??? any videos or sound clips?? i think im going to do the cobb downpipe and stock cat back just like the trurboxs stealthback. are the gains good on the cobb downpipe?
