last time i had my exhaust replaced, it was cheaper to have a straight pipe put on than buying a new cat (which was shot) the engine isnt knocking or clunking like it does with bad mounts, i had a 16v with bad mounts. Its all smooth, just exhausts start to come apart too often.
Exhaust isnt anything fancy, decent muffler with dual tips exiting. Nothing rice. I hate rice. as far as opening the car up, I run Castrol GTX 10-40 in it (high mileage version) and run 92-93 ocatane gas most of the time. The engine makes a very high pitched rapid pinging sound in excess of 4000rpm so i dont hot hod it. My other 16v with less mileage didnt do this. I know how the engine works, but im not brave enough to work on it myself. It would seem to me that the rapid high pitch pinging was from the valves floating at higher rpm's because the value springs arent closing them fast enough anymore. Ive seen higher tension value springs advertised before which led me to this thought. (though im probably wrong) - The engine almost has 160,000 miles on it and has never been rebuilt. When i had my suspension, exhaust, mounts, and axles/cv's replaced last summer, while picking up the car, the mechanic mentioned to me that from what he could tell, whoever had this thing before me drove the holy pants off it. I read on this mailing list about year ago someone commented that solid front mounts are more stable, but there is noticably more vibration, which I wouldnt prefer. ----- Original Message ----- From: "Anthony Pelletier" <[email protected]> To: "Adam Frank" <[email protected]>; <[email protected]> Sent: Friday, June 03, 2005 12:42 PM Subject: Re: [a2-16v-list] Exhaust pulling out. > What is it for exhaust? > > Stop babying that car.
