Im planning on doing a resonator delete on my stock c43 this coming weekend. From what Iv been reading on here I understand that I will need a 2 to 1 pipe entrance for the front part and then the bypass pipe thats cut to the correct length. My question is is there any welding required? Also the bypass pipe should be the only pipe I am cutting just so it is the correct length? Thank you all for your time n help.

if you remove centre resonator you don't need to cut anything.
if you remove 2-dary cats you will have to cut.

i didn't cut my exhaust, only had the resonator removed
first 3 pictures seen is my replacement part which i bought from the motherland of my car

last picture is taken from others, this full pipe kit is needed if you remove the 2-dary cats

Kowalski man Thanks Iv read many of your stuff. Thats what I was assuming so it shouldnt be too hard of a weekend project im excited. And since the cats arent going to be messed with it shouldnt throw a check engine and also emissions shouldnt be a problem!

You can remove both secondary cats and resonator and it won't throw a CEL either. Same story with emissions, you'd also be all good. I've done that and passed emissions tests 3 times without any issue in different places.

I'd look around for videos and sound checks to find what you like better. Just removing the resonator won't make that much of a difference. But you'll like it if you're only looking for a subtle change.

A lot of guys here - including myself - have removed the secondaries (cats) and resonator.

I removed my resonator aka "Straight pipe" on my 99 C230K and intalled the C43 AMG Muffler with the 4 Cylinder growl coming out sounds pretty good. But i have not done my 99 C43, it is all stock muffler exhaust. I was thinking straight pipe "Resonator delete" on the C43, but i havent put alot of thought into it lately. Is it worth the growl??? Kind of eyeing to do it sooner or later.

FrenchBenz

Well, you have two primary cats, two secondary cats and the resonator before the muffler. So removing the resonator only won't change a lot but will give you more growl... removing secondaries and resonator will let that V8 make itself heard for sure

Here are 2 videos of resonator delete only

And 2 videos of secondaries + resonator deleted

It would not effect emission much if resonator and cats are deleted?? I live in Los Angeles..... California F'in emissions controls are hard on us.

BTW I got a little exited there at the small rev cats & resonator delete. I'm all tingly and stuff......

some peepol don't want their exhaust to be too loud.
only resonator delete will give you more growl than stock system which is fine to me.
I didn't want to ruin my exhaust by cutting it down.

if you want better soundperformance remove your cats too.
car will sound like this, sound from the pipes gives me wood everytime

Nice to see my pipe in the last photo

I can confirm that removing the secondary cats will NOT be a problem with emission test. In my country (Switzerland) we also have very strict emission standards and the C43 passes each time (every two years) with absolutely no problem at all. Removing primary AND secondary cats may be a problem.

I believe that in California you also have a "visual" with the emission test and if the exhaust is different, you may get a fail. I'm not 100% sure though.

Iv seen those videos on youtube and Im thinking at least starting with the resonator delete. I have too many tickets to go resonator and cats delete that will for sure get me noticed! lol

LawRens

This is true, but only of the primary catalytic converters. Most smog technicians don't even bother to look for the secondaries, and they certainly do not care about the resonators or mufflers.

Unless you pissed off the technician. Then that's a different story.

I may do the resonator delete on mine. I'm really hesitant, because I live in the deep south. So many rednecks around here with ****ty exhaust on their pickup trucks and old camaros, and I REALLY don't want to be mixed in with them.

DRBC43AMG

Just with the resonator deleted you will get a nice growl like with the resonator mounted but louder. In any case, if you don't do a WOT in front of a policeman, nothing will happen and if you just cruise, nobody will notice.
Just look at all the modern AMG's, I just wonder how they get away with their exhausts and cut out valves, etc..

this is where i bought my soundtube.
http://www.ebay.de/itm/Mercedes-C43-...item338740d673
i paid 279 + 30 shipping, in euros.

this dick now increased the price with another 1000 euros, total price is now 1279 euros for this tube. oh boy, oh boy
real scammer!!

FrenchBenz

Damn this guy is nuts I wonder who will be dumbed enough to throw over $1.2K in just a section... There's no even a muffler or high-flow cat haha. Straight crazy!

KJI3jflarryfe93

i'm glad i bought my pipe just in time few months ago.
i hope he made a typo while he was drunk?

DRBC43AMG

^+1 totally crazy. Just wait to see the price drop when nobody buys

KJI3jflarryfe93

first it was 299 euros, he dropped price to 279 because few were sold so i bought the pipe for 279.
now he raised the price to 1279 euros
business must be slow in germany?

i guess he has to feed his family

DRBC43AMG

I guess a 1 slipped in front of the price. For 279 Euros that is a great deal and if it has a good quality build included, then I would not hesitate.

KJI3jflarryfe93

if you check his auctions for other Mercedes soundtubes they also cost over a 1000 euros, i don't think this was a typo from him.
he did a priceadjustment increasing the price

Minibenz

I've seen this before on eBay when the seller does not have inventory but wants to keep the item active. They bump the price, usually by $1000, until inventory is available. Ask seller to find out for sure because he just sold on 11/7 for euros 279.

jgro1976

Anyone know if it's possible to buy one of those in the states?

Sulaco

a decent exhaust shop could fab one up for you.

Hi all,

Just got this straight pipe from germany (Ebay), great quality, despite the back attachement needs some adjusting (bending) but installation went without any major issue,
Resulst is... well... quite disapointing, sound is only slightly louder but really difficult to notice from the outside,
From the inside, well, slightly more noticeable,
The real gain being actually some kilograms on the stainless steel pipe !
