I'm looking to upgrade from stock. I've been reading for awhile still I know very little. This is what I want:

-More Power/ Better Fuel Mileage
-True Duals
-Cut out cats
-Flow through mufflers like the SLP loudmouths
-Chrome tips
-Low Deep Agressive rumble more like a mustang than a 4 banger Jap-Trap
-Would prefer not to have it crazy loud in the cab

Is this a good system for power and nice sound? H or X pipe? What would this system run cost wise? What tips sound best and what angle?

 

For best power I would stay SI/DO. If you must go true dual go with 2.25" pipes.

I take it you have a V8. Theres no way a V8 with sound like a 4 banger jap trap but a 6cyl certainly will.

If you can find a place to cut out your cats good luck, and dont forget MIL elliminators.

Magnaflow, Borlas, SLPs, Dynomax Bullets, all flow through and will sound good but will be a little noisey in cab since your going true dual and removing the cats. That really increses the interior volume.

 

Work is done here. You pretty much covered it all, Darren. lol

 

How bad will the cab noise be? yell at the passenger seat or just steady rumble?

I don't care for the Magnaflow or flowmaster sound what has good flow and won't be crazy in the cab?

what as far as tips?

X or H?

What does the average true dual system cost?

Why go SI/DO won't true dual give more power?
sorry just have lots of questions. I hear people redo-ing exhaust and I just want to get it right the first time?

 

Steady rumble

Borla is good

I suggest 4x18" Tips, Stainless Steel

X pipe, helps balance better than H pipe.

Depends what you get with true duals, anywhere from 300 to 700.

Si/do will give more, true dual has more flow, which reduces backpressure and low end.

 

Steady rumble. Yelling if your over 2300rpm.

The manufacturer models I listed above are straight through designs which are healthiest for performance.

Whatever you like is what tips you should get.

X pipe cross flows which retains healthier and stronger scavenging to keep low end power and performance perfectly leveled and helping prevent running the slightest bit lean.

$200 - $300 installed.

Single exhausts are better for pwerformance in 5,000lb+ pick up trucks. 3" single to be exact.

 

First what motor do you have?
Second how many cats does your truck have stock? Half way through 05 they switched from 4 to 2 cats.
I will assume you have a 5.4, I will also assume you only have 2 stock cats. Keep in mind if its not a v8 ignore what I am about to tell you
If you run true duals don't go any bigger than 2.5" if you leave your cats alone, some think you loose power with that size but I didn't loose any. If you do for some unknown reason take the cats completely out, which I highly warn against then don't go any bigger than 2.25". Run either an x or H-pipe. X-pipe is easier to get, usually cheaper and makes a little more power while slightly reducing the sound level. H-pipe has to be custom made, so its more expensive and is slightly louder. For a muffler if you don't like maggie or flowmaster, then I would suggest borla or dynomax, or run straights. Tips I only run 3.5" and stainless steel but 4" is very popular and will be a little louder, basically it comes down to which you think looks better.
My true dual setup is straight 2.5" pipe into a custom built x-pipe turning out lightning style through 2 3.5" ss tips. It is very loud in the cab and very very loud outside the truck.

Oh and BTW if you don't want it crazy loud in the cab make sure you leave at least 2 stock cats(if it came with 4) if it only came with 2 then I would suggest leaving them alone. If you have to mess with the cats don't just take them completely out, at least put some high flows back on.

 

I think ive been convinced that true duals are no better than SI/DO. Just thought that better flow meant more power and assumed more power meant metter mileage.

I believe my truck was born in april so should have 4 cats.

I do have the 5.4 sorry.

If true duals are not any better performance wise. Why do poeple run them?

Once i pick out a muffler will the shop fab up all the tubing for a SI/DO system?

Still learning bout all this. and I'm still open to suggestions?

 

I don't know why everyone runs them, I ran them because I like the way they sound. They are louder, and more aggressive than si/do. Ya just pick out the muffler you would like and a shop will build your system.

 

Well I wanted them because that is what FX4LIFE has and his are kick a$$ that sound is exactly what I want.

 

Then PM him, ask him what he has and run that setup.

 

I know what he has that was what my original plan was. But i also want to gain power too.

 

You definitely won't gain with True duals, unless you have forced induction. I am running true duals, for the sound and the volume of the exhaust.

 

Well now im just curious. How does backpressure help? Why would resistance make the engine run better?
Isn't the purpose of the exhaust system to get the exhaust gasses out of the engine as efficiently as possible?
just want to learn more about these great trucks!

 

Darren, fire up your exhaust scavenging speech. lol
