Hi guys
I have my 2012 c63 sedan, and I deleted the resonator and replaced with a straight pipe. I tuned my car at a local bodyshop, they claimed that the tune is gaining 92hp, which I do not know what brand it is. YAP, I am noob and I think I shouldve asked them.
However, Now I wanna have a bit lounder sound and meanwhile to keep the deep tone of amg exhaust. What should I do? just delete the sec.cat and replace it with x pipe or straight pipe?
btw, I also feel that with resonator deleted, I kinda lost a bit of back pressure. Anything to do to correct this?

I've been listening to videos on C63s forever, trying to understand everything and how each part of the exhaust changes volume, pitch, and grunt sounds.
The best I have heard is long tubes (deleted primaries) with deleted secondaries (straight pipe in place of secondaries). Everything else stock (stock resonator, stock mufflers). This maintains the AMG "bark" and sounds downright EVIL on partial and especially WOT.

Thanks a lot for this guys...it finally is starting to make some sense. So my exhaust guy mentioned that as long as the o2 sensors aren't messed with there shouldn't be any issues with error codes. Does that sound right?
If that's the case...any mod that would happen would be after the o2 sensors/primary cats area anyway right? Then I should stop worrying about any error signs going off?
When you say remove secondary cats and resonator with the x pipe, how is that any different than putting a straight pipe there? What is the difference between a x pipe and straight pipe? I see some people removing those and putting straight pipes.
What is mike's power pipe? Isn't that essentially just a straight pipe or is it a x pipe?
Delete resonator or secondary cats or both? Why and why not? Some people say one or the other and some people say both? What is the difference?
Do I have to get one of these pipes or can I just not get my exhaust guy to fabricate some for me if he says he can?
Thanks a lot guys I feel like I am finally making some progress about this. Also, please advise if someone has any experience with this stuff voiding their warranty. That is probably my biggest concern as my car still has around 3 years of warranty left.

I would recommend keeping the secondary cats, and don't go the x-pipe route.

I'm thinking straight pipe to replace the resonator as well and keep the secondary cat
Although I wonder how it sounds ...
Don't seem to be a popular options to do just the resonator

Start with removing the secondary cat. Add straights in its place. This will make it louder but keep the AMG sound. If you remove/replace the resonator, it will add rasp and change the sound.

I have always thought that the rasp comes from removing the secondary cats and removing the resonator will actually keep the amg noise

Some like the sound of removing the resonator, some don't. Some remove both and make it extremely loud. I always suggest starting with the secondary cats and then if it's still not loud enough, then you can move on to the resonator. I removed my secondary cats and put in straights...love it. Sounds healthier and about 40% louder while keeping that deep AMG sound.

Do you get any droning with your build (deleting the sec/cats)? I think my mind works just like yours - I want to keep the original AMG note, as it's unique and raw. I own a C63 Black Series, and the exhaust is already kinda loud when you hit the gas.. But on idle, or when smoothly cruising, is just a sweet sleeping beauty. I want it to be brutal even when I'm at 5mph. lol. Just kidding. Lie, I mean it.

Hey there mate, I'm down to two options here: a very expensive one (full iPE for a actual reasonable price) and a cheap one (deleting secondary cats).

. The cruising and idle sound is increased a little bit but it will still be a wolf in sheep's clothing. Any amount of gas given to it though, it really opens up. Just the other day, I accidentally down shifted twice...I was only expecting the sound of one downshift. When the car shifted again, It literally scared the sh*t out of me and made me jump lol.If you want the absolute brutal sound, adding headers would be your next choice.
I def would go with the secondary cats removal, also lower your rear seats

Mike's Power Pipe Contact Info.
Guys may I suggest is the following:
Some on here are new and might have limited info on these cars.
Essentially
Here's what you need to know to mod this car the right way.
IN NOW WAY AM I SAYING BUY MY POWER PIPE
Any monkey at a muffler shop can hack your car up and charge $100.
They will put aluminized pipe ( The OEM pipe is stainless steel )
Your $100 job will be bent on a regular bender ( kinks and squeezes the diameter ) not mandrel bender.
A mandrel bender is crazy expensive ! It bends the pipes without making any indentations or kinks so the bend is a true diameter ( never shrinks at the bend ).
In the end your car will have a cheap hack job ($100) that belongs on a yugo not an AMG Mercedes..
To each is own; some don't mind putting cheap components on your car, then hey more power to you.
I respect everyone's opinions on this forum and I have been around here long enough, and have met and worked with enough people on this forum from around the world that can vouch for me and my parts.
As for the straight X and H let me fill you in since some of you haven't read the whole thread.
I made all versions before making the final 2 H and straight.
The X kills off a bit of the AMG sound and makes it more high pitched ( more exotic sound ) works ok when headers since it quiets the car a bit.
Some might not see it but once another AMG get next to you with straight or an H you will.
BTW I'm working on a H set up for headers that will make this car livable ( more on that later )
Guys just a word of advise:
DONT PUT CHEAP ALUMINIZED PIPE on a 60k car for gods sake! Lol This is not a 79 Trans-Am lol.
What ever you do make sure they
A attach your mod with a quality flange ( stainless steel ) that will let you bolt on it and off easily and not turn into a ball or rust along with your aluminized $100 piping.
Use 409 or 304 stainless steel.
Educate yourself and I don't mean just take what I say. Do research on the material and the mod you're making. Ask questions it's your $ make sure you feel good with your mod.
Hope this helps

I'm interested in your power pipes for my c63.
Can you please post your email or phone number so I can get in touch with you?
Thanks

Hey there guys,
I have a H pipe exiting into straight pipes that replace the resonator and am interested in upgrading to some exhaust headers.
I am aware of the headers available, however will the long tubes be compatible with Mikes' H pipe set up that replaces the secondaries ?
TIA

Someone clear this up for me because I've called 5 different muffler shops and 4 have told me deleting any cats is illegal. Is it something that differs by state? Or anyone know of anyone near the Charlotte, NC area that will do it?

Is there any downside to replacing secondary cats AND resonators with straight pipes? A lot of the posts I see recommend putting in an hpipe for secondary if the resonator is gonna be deleted too.

I just did a secondary cat delete on my C63 507. Replaced them with straight pipes from Mike's power pipes (very good quality prefabricated kit - fit like a glove). I took Mike's advice and did the secondary cat delete only with straight pipes (no H pipe for the cat delete).
I'm very happy with the enhanced growl and the popping when you come off the gas or downshift.
Not sure about the resonator delete.

Is this one of those things they cannot openly admit on the phone but can take care of once I drive my car in?

Thanks, this is what I was looking for! I think I might just go one step at a time and straight pipe the cats first. Did you have any trouble finding a shop to do it for you? I called a few places and they all said "sorry its illegal, we cant delete cats".
