The Bronx Bull

Purchased an '02 SS last week and she sounds real nice. It came with the SLP CME from the factory and all I've been able to tell so far is that there is an SLP loudmouth attached as well - it's too damn cold to go crawling underneath the car!

I snapped a few shots can someone tell me what's going on here? It looks like where the Cat is supposed to be theres a Y-pipe, which goes all the way up to the exhaust manifolds (which I believe are stock)?

Anybody fill me in here as to what the previous owner did? (not that I'm complaining!)

Here is the CME (stock setup):


Going into the loudmouth:


What's going on here? You can see the heat shield - isn't this where the cat is supposed to be?:

No cats buddy.

Maybe - but that would mean an O2 simulator lies somewhere? No SES light...

I really need to take a closer look at the whole thing but its like 15 degrees out.

Could be that there is o2 sims somewhere on the car. But he could of had the rear o2 sensors tuned out of the car so it wouldnt throw an ses light.

Take a picture of the exhaust further towards the front of the car if you could.

The Bronx Bull

Will do, first thing tom afternoon.

Let me ask this - where, on a stock Camaro SS, do the pipes branch off into each side of the exhaust manifolds? It can't be down near the cat...

Trying to find you a picture.

This would be a system with long tube headers and an offroad y-pipe=meaning no cats. The cats would be up close to the engine tucked into where the headers are coming out of if you had cats.

You probably have cats. The Y pipe is 100% stock. Its pancaked on the driver side like that from the factory. If you follow the y pipe up to the engine thats where the cats will be. large oval type shaped hunks of metal .

The Bronx Bull

Thanks man!

So stock, the Y pipe wouldn't extend that far down? So I'll assume that not only the loudmouth was added, but some new pipes more towards the engine?

The y-pipe would go up towards the engine, go into your cats, then to your exhaust manifolds.

The Bronx Bull

Ahh ok. The 3.8 Camaro sitting next to my LS1 had the cat (singular) right above that heat shield so when I didn't see one on the LS1.. I assumed it only would have one converter but I guess they have two.

Thanks guys!

Honestly it looks to me that everything is stock until the y pipe merges then after the merge is a larger pipe than stock, then that big slp muffler, then custom piping to the CME tip.....

The Bronx Bull

Makes sense... the muffler that came with the CME is gone (crossflow) and the SLP resonator was put in place... so I'm assuming he had to run some custom piping to match up with the existing CME pieces.

Looks like you have already figured it out - your car never had a cat at the location in question (there were only two from the factory - one directly off of each exhaust manifold), and that looks exactly like a Loudmouth setup, which would not be hard to use with the factory CME. You can pretty much run any exhaust with those tips - I even have duals all the way out the back with those tips.
