Magnaflow kit 15924
BTW, the Magnaflow kit 15924 that he gave me had the 3 1/2 down pipe, which should be fine with my stock engine. Rest is all 4". The most I would ever do (after DTT) would be a EZ and 275 RV injectors. Kit was all Stainless Steel including mounts, clamps and muffler. Seeing that he is a wholesale warehouse, I will let him know about the controversy about the down pipe in this kit not being 4" in some cases.
