Hi

have a 97 Audi A3 1.6 acting up
Symptoms:
1. poor idle sometimes sounds like a misfire
2. Low in power
3. Rattle from the exhaust around Cat

I am thinking that the cat has collapsed causing a back pressure
appreciate any ideas or if agree if i am on the right track

I am planning on pulling the cat tonight to see what falls out
is it much of a job?

also if the cat is goosed can i weld in a straight pipe and what effect would this have

thanks in advance
