I do remember reading on the forum here awhile back that supercharged cars dont need any back pressure. I cant seem to find the thread though.
I have watched everyone who has ran header, straight thru exhausts, set ups to cat deletes, resonator deletes....without much of a change...some say a 4-10hp increase, but I just don't see it...but, you ask about changing your exhausts to this direct approach...and I am just saying for a direct approach, the cut outs are a cheap fix...whether they work for you or not, it certainly won't cost you much to find out....not saying here, which is best or not....I will do a resonator delete just because of the weight, no other reason, and if I gain something, then grt...good luck either way...
