Xsi horrendously down on power.

[Grant]

Only just seen this and CBA to read through the 3 previous pages of posts, so if someone has already said it I apologise.

My cat caved in on itself and blocked. This blew a hole in the fire ring, so the exhaust was blowing from the cat/mani joint. Consequentially little or no exhaust gasses were passing the lambda so the car was over fuelling like a bitch. Im talking 130 miles to a tank here. Combing the horrendous amount of back pressure with the lambda being bypassed and there was feck all power.

So, is your cat ok, and how bad is the joint blowing?

I was surprised how much better my car went after having the new cat on, the power loss just creeps up on you and you dont notice too much...
