Hey guys,

So I've been contemplating what I want to do with my 2003 C32 amg's exhaust system, and this is what I've come up with...I want to delete the secondary cats, run dual 3" pipes back to two glasspacks (one on each pipe) in place of the resonator, then straight back to a 3" dual in/dual out muffler. Has anyone ran anything like this before? I think it's going to sound great, what are your guys thought?

Go down to 2.5" pipes.

I have the exact setup you mention, minus the glasspacks. I have a resonated x pipe muffler in place. Let me tell you, it is loud! But it sounds really good. I've yet to hear one person say it sounds bad. I was actually looking for ways to quiet it down. Which one is quieter? Glass packs or X-pipe muffler? By the way, I have 2 3/4 inch pipe.

here is my 2.5" With High Flow Cats

I believe the glasspacks will quiet it down a little more than your x-pipe muffler because I will have one on each pipe, and a muffler in the back. I want to run 3" piping with this set up because I think it will gives me maximum flow and still create enough back pressure. Im hoping the glasspacks and whatnot keep it to a civilized tone lol. When I delete the second cats is it going to trigger a CEL or cause any issues?

Dang, this must have been ridiculously loud huh?

Just got back from the shop and there is no way I am going to able to fit two 3" pipes under there, so I think I'm going to take it down to either dual 2.25" or 2.5" pipes. Should still sound great, and maybe this way I won't loose any low end torque. It's going in Saturday morning so we'll see.

no. deleting secondaries should cause no issues/CELs. No O2 sensors there. only on the primaries

That's what I thought, but it's good to hear someone else say it as well.
