Also, for anyone who is interested, please visit this site to understand how a catalytic convertor works!

I hope that helps clear up some questions.

that was a very good post about emissions, im glad you mentioned it to us.

 

I love that site!!! I used it a few months back. As dumb as this will make me sound, after driving a stick for almost 10 years I finally got curious about how a clutch works. The howstuffworks site showed exactly what I was after, and simple enough for a dummy like me to understand.

 

Thanks! Very helpful!

 

I have a question that I hope someone can help clarify.

I own a 2002 Ford Escape with the 3.0L. The exhaust system (behind the cat) runs through a HUGE resonator, then through an approximate 4’ length of pipe and finally to a tiny muffler 12” from the tip of the exhaust. The system is so quiet that I can hardly tell that it is running. Not that that is bad, it is the purpose of the muffler of course. Well, for fun the other day I unbolted the muffler flange and completely removed the muffler from the exhaust system leaving only the HUGE resonator. When I started the engine it sounded exactly the same. It was absolutely quiet at idle and no different when revved up. When I shined a flash light in the resonator it looked full of baffles. When I looked through the muffler I could see completely through. It reminded me of a cheap glass-pack muffler.

My goal is to free up the exhaust a bit and NOT touch the cat or affect the emissions in any way.

My local muffler shop said that they could cut out the resonator and weld in a Flowmaster 40 series, then run a straight pipe the rest of the way out.

Q: Will this alter my emissions? I need to be able to pass in California.

Thanks for any advice.

I am looking to gain about 1/2 hp, can anyone tell me how to remove my smog pump?

 

Removing the smog pump is as easy as unbolting it. But don't bother. It will make your vehicle illegal and you can pick up power with free flow exhaust and improved intake. Legal and a much larger horsepower gain. Removing the smog pump will devalue your vehicle and my cause problems. Any power you gain by removing it would not be noticed.

 

Hi nieking,

Find out if it's legit to run w/o a muffler on your system!

Did you road test / run your vehicle w/o the muffler to check performance?

Incorporate a muffler w/ bigger openings to also keep it legit (legal)!

California is big on emissions controlling...cut your breathable air w/ a knife, you can!
