Ok, 2002 8.1L 2500 HD. The cats are SHOT, so they are going to be gone Soon! And while im down there I wanna change the exhaust. I have the Corsa system for my truck MINUS the muffler. So I was wandering if a single Flowmaster would be a good choice. It will only be temporary, prob about 6-8 months. Seeing as how the rear mount is going back on soon. Will a 44 series flow enough or something of the sort. dont wanna pay a ton for a muffler seeing as how it wont be on long term, but I want something decent

If it's only temporary no need spend that much on a flowcrapper muffler.

I have the 2001 8.1 3500HD DRW. I have the Flowmaster 70 Series Big Block II Muffler with 3 inch Dual In/Dual Out and it sounds great, and performs good. Heres the link to Flowmasters website with a audio sample track of the muffler.

I used the 8.1 dual 3in. in single 3in. out. A lot bigger than40 series but fit in stock location and sounds pretty good. Hopefully down the road ill be switching to magnaflow.

They're good. A flowmaster 80 series is on my mind, how is it?

I bit the bullet and bought a flowMonster. Got the 3"in, dual 2.5" out. Hope it works good.
