Hey i have 95 EGT (which most of u know) but i think it has cat-back exhaust.. and scortegegt sed his was runnin way better after he cleaned it out.. how much better does cleaning it out do.. and how much work is it to do?

All cars have cat back exhaust. If you clean it out by holowing the honey comb out it is said that you couls gain some more horseys. I think it´a about 5 to 10. But remeber if they do emmisoins where you live your car won´t pass. The cat is what makes it legal and cuts down the polution. I did it to mine and did notice the difference.
it´s not to hard just got to get to it. To hollow it out take a screw driver and hammer to it. Thats the easy part. Getting it off ain´t to hard either.

Nuke - what are you talking about - the converter or cleaning the pipes after the cat? I noticed that my catback has a build-up of carbon and am going to clean it out in the spring. In some cases, the buildup is about a 16th of an inch. do the math and that translates to appx a 2.7% loss in exhaust flow due to obstruction. Compare that to horepower and it´s about a 3.8 hp loss, not a direct comparison, but I think you get the idea.
