Ill be buying an 04 ss supercharged pretty soon and i've been looking at the flowmaster 40s...but when i search for one there aren't any that say they fit on an 04. Ive read posts with people saying that they have the 40s and was wondering what is the part number to the one that fits an 04?

 

All you have to do is cut the muffs on and weld the 40's in place of your stock muffs. Or just upgrade your entire exhaust with the 40's (headers and 3" pipes).
