Default I hate to do this. But I can't drive my car. Exhaust help ASAP.

I hate to make one of those threads.. but I have no choice.

Car is 2007 Impreza. 82000 miles.

The other day I hit an extremely large pothole, large enough for the frame to hit the road.

Here is what I am currently running:

Ebay UEL headers (been on car for over 2 years)
Ebay CAT (throwing codes o2 sensors are probably toast)
Custom catback

It was loud, but not unbearable. Sounded great. My car has been throwing a CEL + Blinking cruise light for over a year. Never affected driving, so I ignored it.

Ever since I hit that pothole, my car became incredibly quiet. It makes absolutely no sense, I mean as quiet as stock.

Now I suddenly have almost no power going uphill, I have to floor it just to get going anywhere, and when it reaches 3k-4k RPM I feel a vibration coming from up front.

I heard there is a possibility of poorly made CATs essentially blowing up on the inside and causing a severe block. So I did the trick of wrapping a towel around my hand and hitting the CAT, sure enough, it sounds like coins in a tin can.

So I'm going to go back to what I used to have, to see if it solves the problem. This was my old set up:

Ebay UEL headers
Custom straight pipe with o2 bungs welded in (Still threw CEL)
Espelir JGT500 catback welded to straight pipe

Sounded like a beast and I loved it. So my question is.

problem solved. the catalytic converter was cheap. got damaged in the pothole, and the insides restricted 80% of the exhaust flow. catalytic converter was cut out and replaced with a pipe.
