I was running true 2.5" duals to cheap-o mufflers and running out behind the rear tires, before the doubler. After putting in the doubler... My friend and I got the passenger side to run along the frame-raiil just above the 205. It is really crushed in there next to the 205 and frame-rail. Then it goes into a flex line and into the muffler. This flex line has GOT to GO! This seems to have the biggest leaks in it. More to the point - this whole setup looks like crap and is WAY to close to my fuel-lines. I put some sheet metal to act like a heat shield on the fuel-lines. Anyways, I was thinking of doing a 90 degree bend off my passenger side headers, bend it towards the drivers side then bend it to run parrallel like the drivers side. Now these two can go into a single (dual-in) muffler and it wilil have a single out, maybe a 3" exhaust to the drivers rear??? Anyone else running doubler? How is your exhaust? Any tips or suggestions? Mildly built 383 (Crane 260 cam) with Fuel Injection. I doubt it will ever see over 5K rpms. Thanks in advance.
