Will i need a retune if i go full catless (straight pipes, res delete and x pipe) ?

Also, will it drone?

roadtalontsi

yes its going to drone (you'll need some really nice mufflers to prevent it) and you'll need a retune for it run correctly and not throw the check engine light for having no cats.

i have straight pipes and theres zero drone, although the car screams a lot louder but it's ****ing amazing

Full catless long tube headers, straight pipes to my mufflers. no drone

RawBenz

Does it change the sound of it though? Cause i love the sound of the C63!

I think mine has just secondary cats delete. If i remove the resonators will it make it louder?

I don't want to remove the other cats cause that means i'll have to retune it.

I am completely cat less zero drone and you still have that AMG sound just this time is more deep if you remove resonators will be to loud you don't want that!

Has anyone removed only their secondary cats and deleted resonators aswell? I'd love to hear what that'd sound like.

RawBenz, yes secondary cats [w/ X Pipe] and Res delete are very common.

LOL "more deep" these cars ****ing SCREAM with no cats put the back windows down next time or put down the back seats and you'll hear how loud it really is without all that sound dampering

I love the raspy scream. Mine has that already. How can i make it scream more? Res delete?
