Exaust

[KennyT772]

Saturday I through my car up on the lift and gave it a full inspection. I found my muffler is starting to rust out on me and that got me thinking about what I should do. I'm already planning to cut out the resonator (2.25in pipe correct?) and now I'm thinking about just cutting out the muffler too.

What kind of effect would it have on the car with so little back pressure?

Also I live in michigan so I don't have to worry about emissions tests or anything so I was thinking about cutting the cat out too. Opinions?

2.25" with either a resonator under the car OR a muffler at the end.

I wouldnt worry about too little back pressure. i was running with 2.5" cat back on the zetec before the turbo and i got a nice power gain out of it.

IMO you can run either 2.25" OR 2.5", whatever is cheaper and easier for you will work well. also, i agree with Hector about only using EITHER a resonator OR a muffler.

Well what would be my best route?

The muffler has a few holes in the bottom, and the resonator looks clean. Would it be that bad of an idea to just cut both out?

i would get the whole system from the flex pipe back replaced with either 2.25" or 2.5" piping and add a resonator or a muffler.

That's what i did and it sounds delicious imo.

There's a little extra pep in the high end too.

How much would a complete exhaust setup cost with a nice muffler? If I put the money into it I would probably go with a dual instead of the single.

You may be able to find an SVT exhaust someone is selling. You live in MI, so I'm sure you can find someone local too. This is if you want to go dual. Cut out the res or the mufflers for a great sounding zetec.

[KennyT772]

I'm thinking I'll get my hands on a SVT and cut the res. Right now the drivers side fender motor mount is top priority, then once I get some cash the exhaust is next. Eventually I would like to swap the atx for a manual...

The SVT exhaust on the Zetec is tricky. You can't really install the whole entire thing, because on the Duratec, the main is located where our flex pipe is, so the best you can do is go from flange-back...kind of. The flange on the Duratec is farther back than on the Zetec. If you want I can snap a pic of the underside of my car tomorrow.
