Right exhaust for my truck!
Ok everyone I'm new here so bare with me!
I have a 2004 ram with the 5.7 an I've been trying to figure what exhaust I want for awhile!
So this is the new plan!

Pace setter longtime headers
Don't know what to do with the cats some one please tell me what's best!
An magna flow 14" for mufflers should I run true dials with 2 of these or run one an y it in?
I want the most flow I can get I already have airaid intake! I'm planning on doing some upgrades like 113 cam, torque conv , throttle body, I also want gears whats the best ratio for power?!
Anything wrong with that an what's the best places for these things

You have a few different questions here....

Exhaust: I'd recommend either headers (look at gibson and other brands also) into aftermarket cats (look into magnaflow) if you can afford it, or just reuse the stock ones they flow pretty well, then for the best bang for the buck do a y pipe into one muffler, or for more money can do dual exhaust but put an x pipe or h pipe in it before the mufflers (x pipe is better). The higher the gear ratio the better for getting a mechanical advantage but it will also raise your rpms as in cruising rpms on the highway, I wouldn't go past either 4.10 or 4.56. Good luck.

Well as of now I have true duals no headers regular cats to x pipe with to bullet glad Packs the turn downs! Want to get longtube headers high flow cats an stay true or go to headers high flow cats to y to magnaflow 14 inch turn down! Which will be louder?

Calebbrown 07-13-2011 11:18 PM

Should I go with pace setter longtube or bbk short tube?

Calebbrown 07-13-2011 11:28 PM

Do the throttle body spacers do anything as a cheap alternative to a bbk?

No on the spacers and if you can afford it...longtubes always make more than shorties..but compare hp to cost! :)

Also look into Fastman TB's...ported stock throttle boddies that are half the price of BBk....same effect :)

coated pacesetter lt's, cat deletes, h pipe, dual cutouts, di/so muffler dumped over axle...just droppin hints here an there..

almost look like cats huh...

You already have basically the best exhaust setup, jut add longtube or shorty headers (longtubes give more power), and be done with it. Dual exhaust with x pipe is the best setup. I would think the loudest would be longtubes with x pipe, mufflers being the same compared to a y pipe. I don't know how you're comparing throttle body spacers to shorty headers....but throttle body spacers are a waste of money you wont gain anything. The bigger/ported throttle body as suggested above should help performance/throttle response slightly.

Calebbrown 07-14-2011 11:37 AM

I wasn't comparing the spacer to headers was comparing it to the bbk TB I saw!
An the cut outs does that just cut you mufflers out o the equation when you open them up! An how do I delta my cats or are high flow better? An also I'm not real sure what I'm looking at in the last picture it's like cats with 3 pipes comin off? What's that? On fast fredies pics!

If you have lower mileage I would just use the stock cats. I think fast freddie eliminated his but he also runs on the track regularly I believe, and his truck is pretty dang fast from what I can tell. If you're extremely serious about that couple hp you could eliminate them, but it would be better to keep them, or get hi flow aftermarket. The stock ones flow decent. I will be putting shorty headers, stock cats, and probably y pipe to single muffle dumped out the side on my truck and will run it on the track occasionally. I'd like to see pics of your current setup if you don't mind, I wanted to do dual with x pipe originally, I'd like to see how it's run on your truck.
