Behind the cat and in front of the resonator is a 12 to 16 inch pipe welded perpendular to the exhaust pipe--pointing inboard toward the cernterline of the car. Can someone tell me what it is, its purpose, etc?

Thanks in advance

 

It's a hemholtz resonator, used to eliminate droning exhaust frequencies.

And you car is also happy to see you.

 

Ahh..I remember reading about it in the specifications. Do all model years have it? It is part of aftermarket catback systems?

 

All 00-06 models have one, although the size/shape changed in 06.

Some Aftermarket exhausts use them, some don't. Just have to look for it on the exhausts you are looking at.

 

Actually, it's used to eliminate a particular frequency. I don't know which one in this particular case.

Helmholtz resonators have a very sharp frequency discrimination -- they are very effective against one frequency and do nothing for any others.

 

I'm not a sound expert, nor do I pretend to know exactly what frequency is eliminated.

Concept is the same. Thanks for clarifying.

 

Is that what you tell your lady? If you go measure it, it's only about 6".

 

I believe that's a Canadian trait. Down here in Florida we have bigger pipes. Must be cause it's summer all the time. You know how cold shrinks things.

I want a Florida pipe.

 

Hey, speak for yourself, buddy
