Exhaust Rebuild Considerations
Hey all, so I'm looking to replace my exhaust system in its entirety (cat and muffler are blown out, truck sounds like LOUDLY shaking a metal bin full of ball bearings) and I had some questions on the feasibility of what I want to do. I searched the muffler thread but that is long dead and didn't think posting there would be appropriate. My main questions are these:
1. I have wanted to do true dual (no X or H, separate pipes from each header) and was wondering about the feasibility of this. Would the 2nd gen 318 suffer from the reduced scavenging? Would there be any benefits that make getting two cats and mufflers worth the cost? Or am I just wasting money being obsessed with wanting two separate pipes?
2. What mufflers do you guys run? Seems most people from the muffler thread liked flomaster/magnaflow, but how would the exhaust sound be affected by only 4 cylinders venting through each muffler in the dual system? I can't find any youtube videos demonstrating a difference or change but I figure there would have to be venting half as much exhaust gas.
3. I am planning on getting the pacesetter long tube headers, however reviews I've seen on them are mixed and makes me nervous to get them, but I haven't found any other option for long tubes out there. Anybody have experience with these that can put me at ease?
Ultimately the sound I'm wanting for is a deep throaty rumble at idle, not excessively loud but speaks with authority when you give it the beans. Any help achieving this goal would be greatly appreciated, even if that means being told what I want to do is a dumb idea.

Hmmm. I had imagined the air/fuel mixture being similar in all cylinders as the ECU adjusts the mixture but I suppose this wouldn't always be the case. Although I have read of people removing the O2 sensor entirely, would this be detrimental to normal operation?

That I can't tell you and you ate right about the mixture unless you have Cali equipped truck, if you don't, you are fine. Also it's PCM not ECU

Unless you know someone that can custom bend pipe for you, you won't find a true dual 'kit' for your truck..... In all reality, the pacesetter longtubes, off-road y-pipe, (you can splice a cat into that.) and a single 3" pipe will give great performance, and with the right muffler, a nice deep rumble.

Another issue is no one makes a true duel for our trucks. At least going out the back on both sides from headers. H and X pipes are a good idea, it helps the exhaust flow out better(better performance). Don't go to lager of a pipe or you will hurt performance rater than help it.

The main question then is which muffler. I like the sound of the hushpower pro (third one tested) in this video, but I wonder if that beast of an engine would make anything sound good.

This is the only exhaust system I could find for your truck.

You are probably going to have to take it to a custom exhaust shop to get what you what made for it.

I watched an episode of engine Masters on you tube, and the HP loss between duel, X, H pipes was only a couple HP. X pipe made the most. Duel made the least. I did my own exhaust on my 360 Magnum swap into my 91 d150. Put in an X pipe, and it's dumping just in front of the right rear. 3" pipe all the way. I've got 2 thrush Rattler mufflers, nice deep tone. Sounds kinda Nascarish/monster truckish at wot.
