about 1 month ago i got a 2.1/2 cat bak exhaust on my vz, and in the last three weeks its been playing up, wont take off or takes a ages to take and cuts outs so i went to the shop were they did it and he told me it was catalytic converter and has nothing to do with them and is just normall and it will cost me the full price to fix it,($700) i dont no to much about this kinda stuff and i wanted to know if this could be the case or if the guy just doesnt want to a have to fix it? any help would be much apreciated it also makes a rattling sound when im going slow in drive or reverse but stops when i put my foot down a little bit

Sounds as if it is the cat mate. Get under it and give it a hit or take the cat section off and check. I bought two 200cpi Outlaw cats and got 2 1/2" sections made up for well under $700. So yeah id probs tell him to **** off and go somewhere else.

thanks for that mate, turns out it wasent even a big deal, went to a few differnt places and they all quoted me around 200-250 to fix the problem
