Anyone running cats with their headers
I see a lot of people end up going with headers and "tune" on their C63, but "most" or damn near "all" seam to end up going completely cat-less. I've noticed a lot of those people usually end up doing other mods to try to tame the noise afterwards too, just curious if running catted mid-pipes with long-tube headers into the factory resonator would be less obnoxious than without cats? I added cats to my mid-pipe on my 04 Cobra with a nice sounding out-come and no seat of the pants power loss whatsoever, and I'll just venture to say this car breathed more than probably 95% of the cars on this board, just to clarify that I don't think the cats are much of a restriction.

Good quality 200CEL stainless steel metallic cats will not take away any noticeable power. You might see it on paper, but you won't feel it much. And, they will take away alot of the noise. If you run them with the factory resonators it will still be loud but not like catless. Catless is so obnoxiously loud and IMO sounds like crap.
This is a good cat:

I'd buy that if I didn't see so many fart can cars, and 1978 chevy trucks with cherry bombs running around, I really believe some of the loudest vehicles I've seen have had less than 200 hp, seriously!

A free flowing exhaust is loud. A loud exhaust is a powerful one..
Why do you think an F1 car will break you ear drum?
I'm not talking about some guy with a Chevy truck with blue bombs on it. In talking performance.

There's quieter cars that will eat probably any one of these C63's for lunch, and there's certainly some bad-*** cars that are loud, but IMO, if you're under 800hp, it certainly doesn't "have" to be loud.

The less restrictive (louder) your exhaust the more power.

Try running no exhaust manifolds or headers, tell me how that runs, and I'll even let you "tune" for it hahahahaha.
I hear what you're saying, but many, many vehicles are way louder than they need to be, and I don't want to be "that guy" with the 400-500rwhp car that's as loud as a friggin dragster.

Take a look at that goofy akrapovic video on youtube with that valved exhaust or whatever it is, I'm betting it's one of the louder ones around, but nowhere near the fastest, or most powerful. What do you think makes more power a Wisetech supercharged C63 with factory exhaust, or one with headers and straight pipes without a blower, and yes if you open up the exhaust it will make more power, but it "does not have to be super loud" to breathe super good.

Why pay all that money for a 50hp modification to pay even more money to remove 40% of that mods power(20 hp). Doesnt make sense to me and its not about the "look at me" exhaust note that Merc63 is talking about. This is an N/A car headers are big power adders and if you want to optimize OUR setup you should run fully catless headers with a 3 inch x pipe it has nothing to do with other cars being faster and quieter.

I just can't imagine a measly 500 hp engine being restricted by high flow cats. If this was engine was making "huge steam" I'd buy your 20hp figure, but only with a dyno sheet from the same day on the same car on the same dyno, without much change in the weather. Sorry

My semi-informed guess with 200 cell HFC's on this csr is 5-7 hp max loss.
