Completely wrong. A super single system works just as well as duals. Same sound but less pipe to rot off. 3" single exhaust with a nice muffler. Your engine isn't built so the exhaust flow is fine. No performance to gain unless the motor is built, then maybe.

 

Guys have done dyno tests and engineers have done the math and found there are no significant gains with a CAI or aftermarket exhaust unless you do major engine mods or add forced induction. Anyone who says otherwise is just trying to justify the stupid amount of money they spent on mods that gained nothing performance. If you look at dyno charts of the difference, you'll find the gains are all at high rpm on WOT runs and aren't enough to justify the cost. If you want the look or the sound of either mod, I'm fine with that, but don't do either with the expectation of performance gains.

 

This guy is right. You'd get much better performance (possibly sound?) from changing cams

 

The bottleneck with the triton series engines is the heads, more specifically, the orientation of the valves. Porting and polishing will help but the only real way to fix the problem is trick flow twisted wedge heads. They claim that just the heads on a 4.6 will give you near 100 hp over stock. Do the heads, toss in a mild cam and a tune and then a good exhaust system will be beneficial but until you go that far just keep the exhaust single and if you want toss a noisy muffler on, or do like me and straight pipe it lol. Look into a K&N filter, the GOTTS mod and new plugs and wires (if you have wires). Also you can do things to bring back some lost ponies such as switch the synthetic oil, clean your MAF sensor, run through some injector cleaner, etc.

 

Now that I finally got back to this. Anyone have suggestions on a lift kit? Not looking for much maybe 2 or 3 inch lift. 4 at the most.

 

Depends on what you do. You can just crank your T-bars and put in a 1" block in the rear for a little lift, do a 3" body lift, or buy a 4" suspension lift from Rough Country.

 

4wd already have. A 1" block

 

4x4's have a 2" block. I was suggesting buying an additional 1" block like what comes in the leveling kit. I suppose a 3" block is probably the better way to go though lol.

 

If your gonna do heads and cams all that jazz on a 223k motor your nuts. Lol as far as exhaust you know what you like as far as sound and looks so asking us is useless lifts are the same way you might like bl lifts or might only like sus lifts so something your gonna have to research. With 223k you should worry about maintenance before performance, appearance upgrades. It's a lot more expensive to rebuild a trans or motor or axle than it is to put new lights in or whatever you want to do. If I were you and you wanna keep this truck along time start front to back top to bottom or wherever you wanna start and check/change all fluids, filters, and just get to know your truck and what it needs or will soon need. In the next 100k your gonna need to do something about timing components. Especially if you drive it hard.

 

If you have to ask, you don't know enough to get to radical. As has been mentioned , getting to know your truck and doing maintainence should come first. You could lift the front end a little, look good and put on a little bigger tires. Going beyond that gets you into a whole lot of issues that get expensive fast. There's a lot of things you can do to costumize your truck. Start reading about what other people have done to trucks like yours. There's a wealth of info here from people who have been there, done that, but you're going to have to do a little work to find it.

You have a nice truck. I'd like to have that truck. Go slow and don't F it up.
