got an 03 LS 3.4L i'm trying to convert it to a dual muffler set-up with super 44's mufflers (step 1 into converting my LS to look like an SS). now i know the exhaust pipes my car has are 2.25 inches wide so i got that out the way but now i'm at the flowmaster website and there are 7 different muffler numbers and all are 2.25 inlet and outlet which is great but which one do i get? any idea anyone here has super 44's on their 5th or 6th gen MC what part number muffler did you use?

some of the part numbers are
842446 ($100 each)
842448 ($100 each)
942445 ($90 each and all number below are $90)
942446
942447
942448
942449

any help would be greatly appreciated

 

oh also i have a flowmaster coupon for the 842446 muffler for $60 limit two directly from Flowmaster website, so i'm leaning toward that one the most unless its not the right one..

 

SWEET I just got my mufflers delivered, will post pics soon.
