ramheaddodge98 is on a distinguished road
Default I know Im beating a dead horse

So im in the market and trying to figure out what im going to do for my exhaust. My biggest question is going single muffler vs true duels. Somebody told me the other day that you cant do tru duals...I thought it looked like you can cut right after the cats and run new pipe from there. Is that the case??

If so, is it beneficial to run tru duals or just go with 1 muffler? Is it worth using 2 mufflers? I had tru duals on my 6.0 silverado and loved it. Im a flowmaster guy and love having my loud and obnixous trucks. If i do that do i just run two pipes back, one for each muffler, or do you use a x pipe to help save backpressure? Im going to remove the resonators for sure.

Sorry for all the questions, i have so many people around me telling me this and that, and nobodys answers are the same. LOL

I've always had the understanding that you can't modify the exhaust before the cats . I've seen Chevys with dual cats , dual pipes , going into one dual inlet/dual outlet muffler from the factory . I don't see why you can't do it .

On my 5.9 I've just ran one cat into 2 Flowmaster 40's, and straight out the back. I don't see why you couldn't run off a split before the cat, and then throw another cat in for more flow.

Yes you could do what you just said and cut the pipe after the cats, You can modify your exhaust after the cats anyway you want too. Will it help the HP/TQ It's debatable your adding more restriction with another muffler and adding friction with another pipe. IMO unless the cats are gone it's just not worth the expense on a stock engine.

As long as you have a cat on both sided, sensors in place and a crossover pipe downstream, there's no real reason not to run true duals unless you can't physically fit two pipes and mufflers under there.

Yea true duals are a possibility if you bring it to a good shop. You should look into going from the headers back. True duals basically means both sides breath on their own. The thing is you would have the X pipe in between them to create some backpressure. You will need to get 2 cats and 2 mufflers. You will need to mock it up first to make sure it will work.

If you get a true true dual set up done then the performance and sound will be great!

yes, the 2 valves you see are cutouts...that way when I really want my true dual sound before the muffler...I just open them up..
