Resonator placement

cjfarm111 · Apr 15, 2016

Just curious where we guys have found to be the best place to install a resonator? I have four inch exhaust with a muffler but has a fair amount of drone and would like to quiet that down a bit.

Where does it go out at. Ive had 4 and five inch on my cclb with no drone both exit it the stock spot.
Both strait piped.

Exits where stock does

Maybe its your muffler?

It's a magnaflow?

You have a crew cab long bed.. Thats the only thing i can think of unless the s366 i have and my injectors change the tone of my truck.. Other then that im not sure. Maybe its a vibration sounds like a drone?

Long box yes with a sxe364.5 and I'm positive it's just exhaust drone

Id ditch the muffler and see how it is.

When I install a resonator - I do it upstream of the muffler. My Dmax has both a resonator and a muffler on it - no drone at all with a 7" stack.

Hey thanks! I was thinking that would do the trick.

What did you end up doing?

cjfarm111 · Apr 15, 2016

Trying to find one. Nobody in town has one.

I also installed a resonator before the muffler. But I took the factory one and flared the ends to fit my 4 inch. Worked out pretty well.

So you had a drone with stock exhaust?

David1089 · Apr 18, 2016

No. I had 4" straight back. Problem I had was the pissed off vacuum cleaner sound. Muffler only quieted the truck a small amount. I had originally cut the factory tip off of the factory exhaust and it was flared perfectly for a 4" pipe. That's what gave me the idea. So I cut the factory resonator off the factory exhaust and flared the ends and welded it in place. If I had pics I could show you. I've since went with a 5" exhaust.
