i'm gearing up to redo the exhaust for my 85 camaro.i am redoing it compleatly(including the cat converter).i'm useing all magnaflow parts except,for the tubeing that runs from the converter to the muffler(which will be fiberglass roll tubeing).i'm stream lining the system and useing a muffler w/tip.my question is how do i find out the size of the tubeing used on the car?besides after i take it off.is there a website or book or something that will tell me?

 

Measure the diameter, that is the size of the tubing

 

the diamater requires that parts come off.i was wondering if there was a way to find out without takeing anything off just yet.i didn't think so,but it was worth a try.

 

Measure around the pipe then divide 3.14... That will give you the diameter of the pipe... Try thirdgen.org ... You'll get more people that know what they're talking about when it comes to 3rd gens.

 

thnx for the info i'll check them out.and i'll br damnd a real use for pie.i never thought i'd see the day that evil teacher was right.
