Braz 08-03-2004, 11:59 AM I just put a new 4 inch exhaust on my Dmax. I heard someone in the Dmax forum say that a guy took his old 3.5 inch exhaust and put it on his 8.1ltr truck. If any of you guys are local to McKinney, TX and want to come get it I would part with my intact down pipe back stock exhaust for $50. I came off a 2002 2500HD Crew Cab Short Bed. PM me if you are intereted. 8100hammer 08-04-2004, 09:50 PM Why 8.1s come with 3 inch duals to muffer from the factory! snoman 08-05-2004, 09:30 AM Yes but one exhaust pipe from muffler. Flow master make a dual 3" in with a single 3.5" out. Even my 2000 K3500 with a 350 came with dual 3" pipes to muffler. Braz 08-05-2004, 10:57 AM Why 8.1s come with 3 inch duals to muffer from the factory! I just thought someone might want it based on a post in another thread. I just didn't want to throw it away if someone else could use it. I don't own an 8.1 so I don't know what they have on them. SilveradoHD 08-12-2004, 03:06 AM I put on a Flowmaster 70 Series Big Block II muffler that used the factory dual 3" inlets and has dual 2.5" outlets. I'm on a quest to get more towing power and this helped. brazos 08-12-2004, 06:44 AM OT: Hope no one gets us mixed up. snoman 08-12-2004, 11:30 AM If he was local, I would take him up on the 3.5 inch tail pipe myself. | ||
