Unhappy Oh great...

Does anyone know where the cats are in this picture? Do I not have cats on my Vishnu exaust system? Are they up near the engine and I just cannot see them? I have a 335i Coupe and now I am worried that the guy I bought from did a cat delete. How would I even know?

I dont think so personally, I guess what I am asking is if there are cats in the picture I posted? Does anyone know, and are they visible on the bottom of a coupe?

Yes, they are right at the edge of the exhaust. There are usually two sets, one there and one near the middle of the car. I'm pretty sure I can see both in those pics.

From what i can see there is no resonators or secondary cats. Im pretty sure there should be a cat in your headers. CEL should be present unless tuned.

No secondary cats, although if you have stock downpipes, then you still have main cats.

I have zero cats and on startup, my car spits black watery shit everwhere while cold

There may be primary cats on the downpipes otherwise no secondary cats. This custom exhaust has deleted them already. You should either have o2 sims, a tune or codes.

The secondary cats are for emissions only and like every one said you have none. Check your down pipes to find your primary cats that your 02 censors are on either side of. These are essential in your car running properly with out o2 sims or tune. PM me if you need to start looking for OE coupe exhaust.

If it is a turbo back exhaust am I screwed?

What, so you're asking us if you have cats in the picture of the car that is not your car?

wtf?

I don't think the picture off the internet is going to tell you whether or not you have cats on your own car.

Just sayin'

I don't think you offended anyone, but it was a bit confusing....

If it looks EXACTLY like that, then your secondary cats are gone. You can't tell from that view whether your primaries are still there.

Having a mechanic look at it would tell you everything you need to know.

Using that picture no secondary cats are visible.

However using that same picture we cant see if your primary cats are still there or not.
