How does the car behave if i have a clogged cat?? I have a Efini so ther is only one cat in the middle of the exhaust under the car...

 

Loss of boost in higher RPM, excess heat in the cat

 

The cat isn't that hard to remove. Mine had a few medium size broken pieces in it, and some smaller ones that could have been clogging things up a little. It took quite a bit of shaking to get all of the pieces to fall out . I was given another cat to put on the car since mine was supposedly clogged. Now that it may not be clogged any more, I may just put it back on the car to see what happens.

"Cheap Bastard" clogged cat mod!!!
