Muffler or Resonator for Delete

If I deleted my exhaust, I wouldn't want to hear the cough-like screeching noise that follows each engine revv. I'm not exactly sure what causes this sound, but I've listened to deleted trucks with either a muffler or resonator installed and I noticed that the screech was far less audible.

Anyone have any thoughts or experience regarding the use of a muffler or resonator with deleted exhaust? What are the different types? Who are some good manufacturers? Are there any down sides to doing this?

Should I replace my dual exhaust tips with a couple mufflers? Or what if I took out my air intake and put a muffler there instead? Any thoughts???

I bought a delete pipe with muffler integrated from street diesel performance. Very happy with fitment and minimal noise increase.

I'm probably looking for something more than a slight sound increase from stock. I enjoy the turbo whistle and a nice strong grunt, just hate that screech noise. I know it's probably not an option to single out any noise, but I don't want to delete and miss out on an aggressive sounding exhaust. As of now, my stock exhaust sounds like nothing to me. I feel as though the only sounds are coming from the engine compartment. Perhaps, I should look into one of these resonators. I haven't exactly figured out the difference between a muffler and a resonator, except for maybe a difference in size. I've seen an MBRP diesel resonator somewhere online.

Does anyone have any thoughts on a 51" Donaldson muffler?

The sound your hearing is the wastegate. Not sure if there is a way to get a louder exhaust without hearing it.

I've started looking at the 51" Donaldson and I'm almost sure that's what I'll be getting. Does it have to be welded? Where did you get yours at? Have any pictures?

I got your PM Dantron, and here are my impressions.

Idle to 1500 rpm, it's a little louder than stock, with a deep tone and decent turbo whistle, but has no turbo "gasp" or "bark" anymore.

1500 rpm and up from partial to WOT, I actually think it is quieter than stock, which makes it really nice and quiet while towing.

I would definitely recommend the 51" donaldson to anyone with a deleted truck that doesn't want to have the annoying turbo sound and cab noise (drone)

I'll try to remember to get some pictures the next time I'm driving my truck. I welded mine, but you could clamp it if you wanted to.
