ugh! the 1800 to 2400rpm......sounds like crap in my truck. I have the stock manifolds going a single 2 1/2 pipe to a 40 series Flowmaster. 1 in 2out. I used to have it all the way to the bumper turned down where u couldn't see it. I wanted a little deeper sound so i sawed both pipes about a foot after the muffler. sounds good at idle but the drone/resonating is there like i have a cutout. If i weld some turn-downs or side exit tips on will it help?

 

Side exits will help a little.

 

And another muffler or Resonator

 

Flowmasters are known to resonate in our trucks.

 

BLOWmasters resonate....period...

 

Magnaflow.... Pure SWEETNESS!!! Quiet idle inside cab. Lopey, musclecar sound exterior (idle)... WOT, will get you admirable eyes! No resonance with the 24" muffler...

 

I have the magnaflow 22", it resonates bad in the cab around 1700rpm

 

agreed, I have a rcsb stock manifolds and 2 1/2 pipe to the y and then its 3 inch back. I had a flowmaster single chamber on it with just a turndown after it, it souded great but the drone was too much, so i swapped it for a 24 inch magnaflow and kept the turndown. Now it really quiet at idle and cruising and when you stand on it it has a nice deep growl that sounds much better, not only that but absolutely no drone at any rpm. Now when I get on it Im not as worried about being such a cop catcher.

 

Can't go wrong with a Magnaflow IMO. I have ridden in quite a few cars and trucks with Magnaflow mufflers and none of them had a drone to them at any rpm.

 

Full body Magnaflows, I find don't drone, the flowmaster's are known to. I put a resonator in a flowmaster system once and it seemed to help. Didn't wuite it down much but took the highway 1900Rpm drone out. Resonates are cheap too, like $150 installed, doesn't need to be fancy.
