Was wondering if I removed it if their was any up/down side to it? When you first give the truck gas it sounds like there is a hole in either the muffler or the resonator. I looked under the truck and there is a knock off flowmaster that goes into the resonator and out below the rear bumper. Thinking of going with a more stock muffler then out the side of the quarter like the V10 exhaust does.

 

After the muffler, many times the manufaturer finds that the noise levels are dampened to a reasonable level, but the sound that comes out sucks. Sometimes it is a frap frap frap, sometimes a tinny blap blap blap.

The resonator is installed to mellow out this noise into something pleasant.

If you put your lips together tight and make a noise with them, it sounds sort of like you are giving someone a razberry.

But if you do it in the mouthpiece of a horn, it comes out mellow and smooth.

The resonator is like the horn. Smooth out the noise, or, in some cases, give it a more "throaty" sound.

 

no i took the rear resonator off and put a straight pipe in. sounds exactly like a stock f250.that rear resonator is ugly and does 0.

 

get rid of the ypipe restrictors and throw a tune in it you'll be amazed. trust me best 400 i've spent

 

He's right,
I have an 04' 5.4. I had my Y-pipes reworked and straightened out, and a dual magnaflow system put on for just over $700. It was night and day. I added a K&N intake, next is a tuner.

 

I dont want it to be loud and obnoxious. I have seen something about a kit to fix the Y-pipe but cant find it. Would a exhaust shop know what i'm talking about if I take it to one?

 

Put the truck on a lift and you'll see the ypipe restriction. Its rediculous how small it is.the ypipe mod and removing the rear resonator made my truck sound like a stock f250

 

Gas Excursions have resonators?

Eee gads!
