I had the rest of the exhaust redone this past weekend. Off the manifolds, it had two cats, 2" pipes, and a super restrictive Y pipe. I had it all replaced with 2.5" pipes and a high flow Y pipe that runs to the 3" section that was installed a couple of weeks ago. Not a single section of the OEM exhaust remains. What a difference it makes. I felt a huge seat of the pants gain with this new setup. It feels really good. Not only that but the sound is amazing. There's nothing like the scream of a V8 at full throttle. Like I said earlier, the Magnaflow keeps things bearable while putting around, which prevents the truck from being obnoxious to drive regularly. I really like how it turned out.
For the motor, I think I have a solution for the time being. It has developed a few leaks and it smokes after idling for more than a minute, meaning the valve seals are going out. Seeing as how it has 190K on it, it's about time for a rebuild, but I'm not too keen on rebuilding this thing. I'd really like to do a Hemi swap, but that's going to cost me around ten grand and I just can't afford that right now. I think a good compromise would be to swap in a 2008+ 4.7. In 2008, they re-engineered a bunch of the components and bumped the power from 235 to 310, and the torque from 295 to 335. That's a really healthy bump in power for what is essentially the same engine. I can find complete engines with low miles, for less than three grand online.
All that I'm going to have to do to make it work is extend the injector harnesses by a few inches, purchase a TB adaptor (they switched to DBW in '08), and have the exhaust rerouted to the manifolds, since the new manifolds exit at a different angle. That's it. That's some pretty minor fab work, really. With this exhaust, a proper intake, and a tune, this thing will feel pretty quick for what it is. All for relatively cheap, too. It won't be a Hemi, but I think it will feel pretty good considering the smaller investment.
