The reason i said cat front is because i dont know what the hell it is called.. My Exhaust is Restricted bad, I am sure its the PRE cats.. Anyone have a pipe that will FIT the Stock Exaust manifold to the front of the main cat? OR better yet a straight pipe that Replaces the cat to the rear of the cat back. If anyone has one please let me know... My car has NO Power at all and it Is Hissing like crazy. thanks 88 gxl stock

You can take somthing and bust out the inside of the cat! The inside is fairly weak. It's like a bunch of small straws. Lots of pepole do this! Then replace it with a pipe later when you find one you like.
