View Full Version : New member/owner, few questions

10-13-2006, 10:56 AM
Hi all,

I'm a new member and owner of a 2.8 q A4 30v and after a bit of searching I have a few questions I'm hoping I can get help with.

My exhaust appears to be wearing out as I'm getting rattling from the exhaust and pops from the exhaust when in gear decelerating. So I think one or both cats are toast, if not plugged. If so, muffler is gone also.

-Now my question is in regards to my Cat options. I've read so many conflicting opinions, I need to ask if removing cats will throw a code. Some say yes, some say no. Either by eliminator pipe or high flow cats, will anything other than stock cats work?

-Also, has anyone seen or bought headers for the 2.8? If so, worth it?

-Also, I keep seeing copper plugs being mentioned as better than long life platinums. Does this apply to 2.8's also, or is this only for 1.8ts? Anyone know the product # if applicable?

Hopefully people with first hand experience can chime in. I'd really appreciate it.
