Nick, do you know of a better y pipe or sell one that would be easily adapted and allow better flow? this one is so goofy looking

I'm just guessing , but , just cut off the pipes before the 'y', and run duals all the way back.

That's what I did on mine. The shop said the Y pipe was very crushed and restricted on mine. From his reaction it sounded like one of the worst Y pipes he's seen. Mine was the first 6.4 in the shop they installed dual exhaust on. Very satisfied with going true dual Flowmaster Original 40 Series dumped in front of axle. Want the Super 10 or Dynomax Bullet next time so I can get it louder.

Would a mufflex with resonator delete sound ok? I don't want the drone but want the rumble. I'm not really sure which route to go.

14 2500 with 5.7l by the way.....

I will be taking the resonator off of my 3.5” mufflex. When i get time. The 5.7 has a much more refined/race truck sound to it with the mufflex. They sound great. If you are worried about noise level but still want the rumble than... IMO... you dont want a flowmaster. They work as a resonating chamber that just so happens to be under the cab of the truck. I however love the sound of a flowmaster but a lot of people dont like a whole lot of in cab noise. Magnaflow/mufflex lets more sound out the back vs resonatong in the muffler.

If i were you i would try the mufflex with the resonator on. You can always take it off later..... or re install the stock if you dont like it at all because there is no welding or cutting “needed” with the mufflex. mine went on in about 40 min.

For anyone interested you can find the Solo Performance muffler delete kit here with a bunch of videos. It has the resonator on for now. I did cold start, warm start, revs, in cab driving and wot videos

So now my question is which level would you go with? Does the resonator restrict sound enough so that the aggressive mufflex doesn't blow people away?

U&A · Mar 17, 2018

I didn’t know the 5.7 had different levels to choose from. mine did not from mufflex.

If you’re a little worried about it being too loud I would leave the resonators on and get the most aggressive one that has a muffler. So in other words one step quieter over straight pipes. Then if it’s not loud enough you can add a bit more sound/rasp by removing resonators.

check out our options from Solo Performance here . We got you covered from mild to wild

Current setup is mufflex with the magnflow and resonator left on.

Going to cut my resonator off tonight. Ill post up in the morning how much of a difference it makes. I don’t expect much if any. If it doesn’t ill at least have removed useless weight and an eye sore from the back of the truck.

U&A · Mar 22, 2018

LOL,

Just cut it off. Only did a cold start and let it idle. Gave her a few revs. First impression of removing the resonator with the mufflex magnaflow setup is it is slightly louder. It may give it slightly more “rasp” but ill tell you that in the morning when I take it for a drive.

Do any of you have a stock muffler for sale? I’d love to get the whole system from the muffler back but if I can get just the muffler thats a start lol. I’m trying to quieten my truck and y’all going louder lol

U&A · Mar 22, 2018

You can have mine for free. But are you going to pay shipping for a 40lbs muffler the size of a twin bed?

U&A · Mar 22, 2018

I would go to your local muffler shop and ask for an instal.... or just a muffler.... that will do what you want. And if the dont work on 3.5”. Go to a diesl truck shop.

Where are you located? If it’s not forever away I may be interested. Lol I know it sounds dumb that I’m looking for one but it currently has a magnaflow muffler with duals and I’m just not a fan of duals. The sounds not terrible but I don’t like the look
