Hello!

So I went to the shop to have my car serviced today and I told him that I want to have the sec cats deleted. He told me it's not a good idea and that I should do a res delete since it's reversible and cheap ($250)

What do you guys recommend? I want something easy reversible because I don't want to worry about mods when I'm gonna get rid of her.

Thanks!

PS: I know it's a C63 forum.

Do the res delete! I just did it and the sound is wicked! I would do straight pipes over x pipe if you want a really rough bark... just what I like though!

Why is it not a good idea?.. Sounds like a great idea to me!

i got both of them taken off with straight pipes i love the sound!

Wow, sound lovely.

I guess you don't have to worry about passing emission just like where I'm at.

Res delete can be done for $150 at a dealer, $50-60 at a third party shop. I honestly think the exhaust sounds great the way it is but to each their own.

This is whats inside your resonator.
Looks like straight pipe with a 1/2 in pipe going across making it a H pipe kinda.
If u do a 2nd cat delete u will gain couple ponies and make it louder.

Replacing the resonators with a x pipe will give you some scavaging effect and maybe a few HP. The sound does change, not much louder but different. Replacing the secondary cats with an X pipe will yield both more HP and sound. As these cats are downstream of the second O2 sensor it will not throw codes. Manufacturers are using secondary cats because of the long warranty they have to give on the emissions system. A relatively new car should pass smog without secondary cats. Returning to stock as only one cut is needed and you can reinstall the stock secondary cats with a slip joint at a later date.

Stick it in the other hole...

Oh wait nevermind you were asking about something else.

Thanks all for the answers but I still don't know what to do. I love the stock sound, I don't want it to change, I just want it a little louder.

VaclavSV

Do the resenator delete! Trust me. It is exactly what you are looking for.

Guilty

Of if you say so! How long does it take?

Edit: I just found this: https://mbworld.org/forums/c63-amg-w...pros-cons.html, it doesn't sound that good

Guilty

I'm at the shop right now and they said they need to cut and I believe them.. But I'm too scared... I don't know how it's gonna sound..

MBfinatic

You will love the sound!

Guilty

I left. I guess I don't have the ***** to do it... because if I don't like it, it's gonna be a nightmare that I'm not ready to live with.

I think I'm going plug my speakers to the exhaust tips. It's gonna sound awesome.

Remove post cat and replace with x pipe. Remove resonator and replace with straight pipe. All good.


On a separate note would the above be good for my C63 Black Series??


I really like the CBS from the factory sound wise but....

Guilty

Vic, if you do it, I'll do it too. lol

Vic55

Its easily reversable... Im thinking resonator first but I have a CBS which seems (to my ear) to be louder than a normal C63...

If I had a std C63 the post cat and resonator would be gone... I did this with my M156 E63 too.

Guilty

I have a CL, it's less loud than the C63 and they told me it's a lot of work to reverse. That's what scared me I don't want the car to have any scars.

Vic55

Your path from header back is longer---- Id do both all day--- resonator only removal will not yield great results.

Its reversable, tell that Midas shop you are dealing with to chill LOL

Guilty

I don't go to Midas :P

It's a benz only shop

when you delete the res you have to replace it with something else?
