Re: buzzing noise

It sounds like broken baffles in the resonator just behind the main catalytic converter. This is a very common problem with our cars. Do a search on resonators or buzzing noises to find out more.


After you cut out the old resonator, you can replace it with a universal 2.5" in/2.5"out resonator. Usually 4" in diameter and 14" long, such as a
Magnaflow 10416 http://www.performancepeddler.com/de...CT_ID=MAG10416

Their advertised price is $58.62, but you can make them a lower offer

or an

AeroTurbine AR25. http://www.aeroperformanceexhaust.com/products.htm

Thier price is about $51.75.


You can also just weld in a straight section of 2.5" exhaust tubing in place of the resonator. Many here have done that, but the resonator works the best for keeping undesirable resonances away.
