Clogged cat
I know my car has a clogged cat and actually didn't pass our check but got through because I just put my wastegate on which is part of the exhaust, what happens when the cat starts to get clogged? I will be getting a testpipe to put in place of when the spring comes but I was just wondering. I know hp will actually go down, but I was wondering by how much. Will effect the spool of the turbo much? Another good question is, does if effect my milage? I have noticed only about 19 with a mix of 80% city / 20% highway driving but even on the highway I only get about 23-24 max.

If its badly clogged youll get weird things like stumbles, hard starts, etc.
