How far back are the cats on an 09 A6? I didn't see any but was just making sure that there was none very far up towards the front. I had my car on ramps in the rear so couldn't see too far forward Thanks.
Since we are discussing exhaust, my 2009 Coupe has the exhaust flowing through: Cats (one on each side), an X-pipe, tube-like resonators (one on each side), then the mufflers. Is this a normal stock exhaust set up???
Mine didn't. I think whoever put the aftermarket (mufflers) exhaust on removed some stuff. Cats are still behind manifolds though. My question is, do the cats usually go if I go with LT headers?

Yes, but you can buy an X pipe with cats if you still want them.
