a resonator just takes some of the high pitch sound out of the exhaust note. On the 3t it really smoothes out the sound and give it a nice mellow note at idle up to about 2500 rpm.
what is a good resonator? and how much do they go for?
But i suggest you check on the fluids and electrical of the car.
i changed the motor oil and filter first thing. the old oil that came out didn't look to bad. the valve cover is leaking so i will have the valve cover off soon and that will give me a better idea of how much burnt oil is on top of the motor. the old lady i got the car from claimed to keep the oil changed. i drained the trany oil and it was clean like new oil same with the rear end. the radiator looks good too, nice and green coolant, no rust under the cap.
haven't got into the electrical very far. the head lights, running lights, brake lights, and turn signals work. i hope there is no electrical problems that come up. i hate electrical problems. i did open up some connections under the hood and they where very clean no corrosion at all. the charge light and brake light in the dash do act a little funny, sometime there both on really bright and sometimes there dim and sometimes there not on. another thing i did was clean and fill the battery this seemed to kill the battery as it will not hold a charge any more and I'm hoping this is whats making the dummy lights act up. i will post back on this problem after replacing the battery
