2020 C63s Tips for a Newbie

Hi,

I recently got a 2020 C63s coupe. it has 8.5k miles and I LOVE IT!!!
However, I wanted to do some modification after owning it for about 5 months now.
I wanted it to be louder as I only drive it on weekends and I want to have fun and be very obnoxious.
I wanted to do air intakes as well. I am very afraid of tuning the car however, those things are always scary especially since it voids warranty. I am looking for suggestions on what to do to make exhaust louder. As well as which intakes I should go with that require no tune and I would be able to hear turbos louder.

Thank you ,
granitg

Slap on a EVM and a VTA, both will add more sound and are easy to do however, now you have to do research as there is a lot of info here on both of those mods.

Good luck and enjoy!

That is confusing with wanting the warranty to be valid. Trolling or nah?

OP: you will void your warranty by making any mods to the exhaust system unless you can remove the mods before you take the car into the dealership.

If I had an EVM I'd be taking that off before visiting the dealers too.

If you have the performance exhaust I wouldn't do that. Just remove the secondary cats.

lol well, I did get a muffler delete and it sounds amazing!
The problem now is my car is in limp mode even though i plugged back the valves and zip tied them near the exhaust. I ordered valve simulators im going to see if that fixes it. If not i will put back the mufflers.

To the OP. You want some suggestions for having what you call 'fun' and 'being obnoxious'? Find a large open area with a smooth surface. Wait until you get a cold and wet day. Take it to that area. Run the piZZ out of it as in:

-Straight line acceleration. Then hit the brakes and lock the wheels. Hard...
-Go into a turn until the a$$ swings out. Try to correct the slide if possible
-Set up a 'cone' and get going at least 60mph. Then avoid the cone by swerving around it. Kinda like being forced to avoid another truck or car due to a sudden stop or out-of-the-blue accident happening right in front of you. Feel the car. Get use to it in a "controlled" setting BEFORE you need to find out on a crowded cold wet road with vehicles all around you. Look closely to see what it can and cannot do.

-Then think again about cutting up your exhaust for the 'noise factor' and wanting to be obnoxious on the weekends.

My boy got a mustang gt, I need to have a car that sounds as loud so im getting a catless downpipes soon and a tune. Just want to fix this limp mode **** right now and in a few months im gonna get those downpipes and tune.
Was thinking of going with Weistec downpipes and tune.

Weistec makes great stuff but expensive. I invested into their bottom line from my previous C63’s. This one is loud and fast enough for a while longer. GL
