ok ok i know this subject has been covered but i have a strait pipe to my 5inch stacks and my head has been killing me since i put them on 5 months age so the question is what muffler to put on i like the sound but not the drone and dont want it to sound like stock either i am thinking about the donalson 51 but i wonder if it will make it too quit please i can use your input

 

A resonator will help kill off the drone a lot.

You can actually install two resonators inline if you want maximum drone reduction.

It will be mild until you floor it, then you'll smooth growl with no drone.

I'd look here:

I single 5" should do it, but dual 5" models (one feeding another) will definitely kill the drone.

Donaldson Muffler. I think I will eventually give in and get one too. So much driving at 75mph...its getting to be nervewracking when you're trying to concentrate....you can get one from the above link Hohn posted...

 

What did he say?

 

not to be cheap or any thing nut those resonators are expense 100 bucks each i think i will look in to the donaldson but i dont know if i want the 51 or something smaller like a 40???

 

I think I will go with the 40. I doin't want to lose too much noise, just eliminate that noise (not really a drone on my truck, just sounds like its screaming!!! 0

 

is the ringing in my ears bothering you? lol.....

 

ive had 2 different mufflers on my truck and they helped alot with taking away the drone in the cab. I dont think it will take it all away but it should help you out alot. I went back to a straight pipe also and man theres alot of drone with an automatic truck

 

I think im due for a resonator but I need a stainless one. Anybody seen one?
Mine vibrates with the single enough that the back window leaks now.

 

I went from a 5" straight through and just recently added a 51" donaldson but I am regreting it. This thing is too quiet now and even when your on the throttle hard you cant hear it over a low radio sound. At an idle outside the truck it has a deep big rig tone but I am thinking of trying a smaller muffler or just a short resonator. However the drone is gone completely. My 4" factory without the muffler was louder than this expandit 5" and donaldson 51". Hope my experience helps you guys out.

 

try the 40" or just a resonator...

 

well i went an got a 36in total lenth muffler strait through design 4in 4out and i am not liking it to much this thing is to quiet i am hopeing it gets louder when i brakes it ?????? like i glass pack but all the noise driving down the road is gone but i guess you cant have it all but i think my ears will like my trip down south tomorrow with 12k in tow
