Help Replacing my CAT

[green97]

For the past few months I have known my CAT was gone just do to the horrible sound that it creates.. so today I decided to take it to a local muffler shop (Midas) to get quote on replacing it.. The guy at the shop said that the CAT alone was $485 (Canadian) because the stock CAT is not universal and I need a special one also said I need to replace all 4 o2 sensors at $122.00 per Sensor, anyways of course didnt do it.. Is there really something special about the stock cat that makes it cost so much to replace also do I need to replace the sensors.. the guy at midas said they need to be changed every 80,000 kilometers..Any suggestions about what I can do to replace my CAT the price almost made me fall over..

Add: I have a 97 Camaro 3.8l

Just get a magnaflow cat off Ebay.It's onely about $50 US. Just get the 3"cat and a 3"-3'coupling and a 3"-2.5"coupling and about 5"of 2.5"pipe and another 2.5"-2.5"coupling and clamps to hook it all up.
A sawsall makes short work of cuting the old one out.
Some places require that it's welded for inspection, so before inspection ask someone .If you have to just have a shop weld all the couplings in place.also very cheap.

There tring to hose you on the o2 sensors, they don't have to be replaced until there bad.

YA a carsound cat will do just fine, just need a little pipe adpating to go on and such.

I have the same problem with mine cat, I bought one on ebay for $60. Next week i'm going to put it on.
Can anybody give a tip on a good exhaust? Magnaflow or Flowmaster?

They are gonna take you for a ride. First of all don't go to midas. Second of all, go a to a smaller mom and pop type place.

There is nothing specail about the stock cat, other than the fact it is expencive.

they cost so much cause you also have to buy the y-pipe with it threw chevrolet. trust me, i was looking for prices on a new y-pipe and they said the cat came with it
