C63 primary cats delete
Hi guys thinking about removing my primary cats, I delete secondary cats already I like the sound, if I remove primary cats!
Would I get any drone in side of the car?
Would the sound get better or to loud?
Would I gain any power?
Would like to hear what you guys have to say thank you for your time!

It's freaking loud. Jeffield did it to his first C63 and I don't think he'll do it to his second one. There is a slight drone when I sat in it.

LTH + no cats will be the loudest. I haven't heard a car with just no cats so I couldn't tell you how much louder than stock it would be or how soft it is compared to LTH.
HP gain if you do LTH + no cats could be within the 40+hp range give or take.

Real loud and you will kill people walking behind the car with your exhaust fumes...
if your planning that get long tubes or it be a waste. You will get more power but not as much as mids or long tubes.

From Wikipedia:
A catalytic converter is a vehicle emissions control device which converts toxic byproducts of combustion in the exhaust of an internal combustion engine to less toxic substances by way of catalysed chemical reactions. The specific reactions vary with the type of catalyst installed. Most present-day vehicles that run on gasoline are fitted with a “three-way” converter, so named because it converts the three main pollutants in automobile exhaust: carbon monoxide, unburned hydrocarbon and oxides of nitrogen. The first two undergo catalytic combustion and the last is reduced back to nitrogen.[1]
So basically, if you eliminate the cats, you can smell all if the exhaust fumes. Not really in the car, but certainly outside.

I am catless, no LTH. One, the smell is absolutely horrible, smells like an old diesel truck. A lot of people will give you the finger because of how loud it is, wether youre at WOT or just on the pedal a tiny bit. i only notice a drone at around 1.5-2k rpm, its bad at 55-65 MPH then it disappears. It will also attract a ton of attention, so make sure you don't get anyone angry. It does come in handy when you want someone to move, just give it a quick rev! I can't tell you anything about gains, as i've never dynoed. But i raced a tuned catted c63 and pulled on him every time so that gives you an idea that the gains arn't bad. You'll also want a crossover, or you will lose some torque.

LTH, no cats, stand behind when it revs and it will knock you down. Very few people remember what real car exhaust smells like, napalm in the morning.

I say let the car breathe
Just keep in mind if could leave something more to be desired, by running no cats on stock manifolds. Good thing is we got a fix for that
Until then, I say try it and see if you like it. It might be what you were looking for, if not hit us up and we can really refine the tone and makes some nice power too
