Contour Enthusiasts Group Archives Forums Modifications Duratec Performance Resonator????

Has anyone out there done this mod??? If so, what impact does it have on performance??? Personal point of veiw(from You); and Technical point of veiw(actual HP increase).

There's a TON of people who remove their resonator from the stock exhaust. When you combine that with a filter like a K&N or KKM, it really makes the car sound nice!!! As far as performance gains, don't expect much. Maybe a little better pull in the high RPM's, but nothing substantial. But heck, for about $140 you make your car sound way better!! Go for it.

BTW, you get more power gains from a cat-back system like the Bassani, or I've heard you geat great results (8hp at the wheels IIRC) from an aftermarket Y-pipe.

I just did my resonator last week & it makes a noticeable hp gain. It feels quicker off the line and makes pre 3500 rpm hp better (high rpm are sweet too). I think this mod added more hp than my intake. If you can feel the difference, it worth the money. I wish that I had this done earlier.

You have to remember, IDRVFAST, what goes in must come out!!!!! So after you put your intake on(to the TRUE power out of it), you need to do some kind of exhaust work.

I have a ZETEC and it gave me alittle more snap off the line and it also sounds a lot better under WOT conditions.
