nevermind i see it now

sounds great was it hard to do?

 

[KMeloney]

Nice! I'd really like more info on this, like if there's now ANY resonance in the cabin, etc.

is the resonator the big can towards the end of the exhaust by the tip.did you throw any codes by cutting this off.also will it still pass inspection.

 

[bocaytomas]

The delete was the easiest thing I have ever done to the truck, I just took a reciprocating saw and cut it out, I then added an extension and that was that, the car DID NOT give any error codes either, you do hear a bit more noise but the type you want, feels powerful, and I never dynoed it but I though you could feel some more power output too.And yes its the big can at the end of the exhaust, I don't know if this will pass inspection or not because here in CT we don't have to do one, at least I never had to do it.

 

[KMeloney]

Does the resonator only modulate sound, or is there an emissions aspect to it, too?

What kind of tip did you put on the end? Have something welded on, or did you use one of those set-screw clamp on tips?

Once this this is cut off, can you have it welded back on later (provided you leave enough pipe to weld to)?

The added noise: is it just a louder, better exhaust sound, or is there some resonance now?

Thanks!

I don't know what you mean by resonance? But there is a bit more exhaust sound, the good type, and yeah I just put a $10 bolt on extender and that's it

Resonance, or exhaust "drone," is a term used to describe when the exhaust note hits a certain noise level/frequency where it causes a moment of (or constant, if you stay in that range) air vibration that, frankly, is like someone has cupped tupperware over your ears. That's really the best way I can describe it. Usually associated with a certain RPM, it might even vibrate interior pieces so that you get a "buzz" along with the noise and exhaust pressure.

The purpose of a resonator is to dampen those frequencies, as I understand it. So, without it, it makes me wonder if there's now some resonance.

Can anyone else help describe it?

its the sound that hurts your ears like the sound baffleing you got when you only had one window open in certain cars. My silverado with flowmasters does drone at 2k rpm. But below you cant even here it and above is a clean rumble.

corsa's website here has alot of good info.

Pretty spot on. An easy way to look at it is, if you hear the sound from the back of the truck that is the exhaust. If you hear it from all around you, that is the drone.

Hope that helps.

keep the resonator on and get the magnaflow 5x8x24 muffler ive done this on a few sounds great and you get no drone

just cut mine off.wasnt as loud as i thought it was going to make it.there is a little more deep tone to it for sure just want it a little louder when it idles and i get on it.
