@gsxr721404 It is a flowmaster original 40 series. The Part number of the muffler is FM42541 and the price is $75.95. If you go to google and type in Flowmaster FM42541 it will come up. This part number is for the original 40 in the correct size for your truck.

What series of 40 is that...sounds great....got 04 I5 colorado not sure waht to get

@gsxr721404 It's the flowmaster original 40 series. It was cheaper than the super 40 and to my ears sounded better. It's loud enough to notice it but not too loud. On the Colorado I like any 40 or 44 series. The 50 series mufflers are not loud enough to notice.
