Resonator Delete Question

I just installed a super 44, but think it's too quiet. I am thinking about deleting the resonator and keeping the flapper open. Will deleting the resonator make a big difference? Will it create a drone? And will the permanent open flap make a difference?

I have a single in/dual out Super 44 on my truck and had them remove everything from the muffler back (stock muffler, resonator and tailpipe) and it sounds really good and is very loud. It does have t

The flap is for v4 mode. Without the resonator it will just have a deeper rumble. If you don't have the flap operational, when it kicks into v4 mode it will sound like crap (based on what other members have said in their experience)

Removing the resonator will make a huge difference in sound. It should make it a lot louder. I recommend relocating your flapper to be before the muffler instead of behind. Having mine behind makes my exhaust sound like its full of holes. Once you do both of those if you dont like the sound still you can clamp open the v4 flapper.

Also I have a feeling with a 44 and no resonator youre going to get drone in v8, and it will be even worse in v4. Any loud exhaust will have some drone, some worse than others.

Yes. I've got 18" Magnaflow with 3rd cat(resonator) and flapper gone... let me know if you do take it off, I might want your flapper.

Not removing the flapper haha, just clamping/welding it open if i plan to go through with it

i have a 4.3l v6 so its still quiet with the 44. i might cut the resonator and clamp open the valve. if i get really bad drone then ill unclamp the valve. what do you think? I dont plan on moving the valve to before the muffler

If you don't plan on moving it to before then leave it held open (don't weld it, just use a clamp or bolt), but yes remove the resonator if you want it louder.

 

Mine sounded god awful with the valve after the mufler. I drove it home from the shop and instantly clamped it open and its been like that since.

It does have the V4 drone because I don't have the flapper valve anymore, but it's not that bad. To me it just sounds like an engine brake/jake brake on an 18 wheeler which I actually like and don't mind. I didn't touch anything in front of the muffler so I kept the 3rd cat, but I may remove it later on.

I too have gotten used to the v4 drone, part of the reason I haven't relocated my flapper yet. I put a drop in dry filter and created a home made MIT as well and with that extra air flow my truck has a nice grumble under load.

because i drive a v6, do you think i won't have a drone?

It will probably be worse because you have v6, if you're worried about drone a super 44 was probably not the best choice.

why would it be worse do you know? i was assuming v8 are naturally louder which would therefore have a higher chance of louder drone/??

Drone is worse when using a v8 muffler on a smaller displacement engine. They dont push as much air through and it gets caught up in the muffler causing the low tones.

      Post your UOA, (used oil analysis) here

      By Black02Silverado · Posted

      Here's the second UOA on my 22 Wrangler with the Ecodiesel. This has 5k miles on AMSOIL Signature Series DEO 5w-40. The first one was dealer installed oil, no clue what it was, the second is what AMSOIL recommended, European FS 5w-40, Most of the Ecodiesel world is showing great results using the European MS 5w-40, I figured I would see how the DEO works. This is using an Ecoguard oil filter. It's my understanding this engine likes to shed aluminum.  We will see. So far I don't think this is too bad.

      Disable DRL's

      By revmanii · Posted

      I'm surprised nobody seems to offer a solution like the start/stop device I put in my new truck. Remembers my setting when shutdown. And while it still starts up in start/stop, it stores/evaluates what mode it was in when shut down and will change it whithin a second or 2 of startup. It'd be nice to have something like that for the DRLs.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      I will be doing that for sure, but I need to solve who has/ where I can find a bidirectional scan tool that will support OBD 1.5. I'm kicking myself because I ebay'ed a Snap On MT2500 that I didn't think I'd ever need anymore. D'oh!! I'd rather not buy another, so I'll contact a few local shops to see if they have one and how much they'd want to do the procedure. I'd rather have the ability to do it myself... I wish there was a modern tool that could do it all, but I'd have no idea what to buy.   The theory with the pulled timing is that it mimics a rich condition. The delayed spark causes incomplete burn and the O2 sensor picks up low oxygen levels. That's interpreted as a rich condition so the PCM pulls fuel and that shows up in the deeply negative fuel trims.

      An ultra wealthy man had the most beautiful daughter. But, there was a problem. Everything she touched would melt in her hands. No matter what, Metal, Wood, Stone. Anything she touched would melt. She could not feed herself. Because of this, men were afraid of her. Nobody would dare marry her. Her father was despaired. What could he do to help his daughter? He consulted doctors, scientists and anybody who could solve this problem. Finally one of them said, "If your daughter touches one thing that does not melt in her hands, she will be cured." He was overjoyed and came up with a plan. The next day, he held a competition. Any man who could bring his daughter an object that would not melt in her hands would be given billions of dollars to marry her. Three extremely intelligent and handsome young men took up the challenge. The first brought a very heavy steel rod, But alas, when the she touched it, it completely melted in a matter of seconds. He sadly went away. The second brought a beautiful diamond, knowing diamonds were one of the hardest substance in the world and would not melt. But alas, once she held it in her hand, it melted. He too was sent away disappointed. So now, there was one left He was very nervous & sweating. He approached the daughter & said, “put your hand in my pants pocket and feel what is in there." She did exactly what he asked. She felt something very hard. She held it in her hand, squeezing it as hard as she could. It did not melt & remained extremely hard. Her father was overjoyed. Everybody was overjoyed. She was finally cured. Nothing never, ever melted in her hand again. They married and they both lived happily ever after, raising a wonderful family. Question: What was in the the groom’s pants pocket??? Answer below ↓ M&Ms of course! They melt in your mouth, not in your hand. What on earth were you thinking?
