Has anyone tried muffler delete? I searched and found few threads about it, but no one really seems to have it done. Also searched some E55s with muffler delete w/ xpipe 2nd cat deletes, sounds not bad.

Only reason I want to do it is for sound and also because I don't want to touch the main cats. If I really do this mod, would I need just 2 cuts and weld on a Y pipe?

I'll be sure to post videos if I get this done

Just leave it alone lol

c63addix

lol why? it would be cool to hear what it'll sound like and revert it back to original for a small amount of $$$ if it's bad

MaroonC63

My friend did it, very LOUD. But not in a goodway, but that's just my opinion. He didn't like it either and reverted it back literally right before he even left the shop. You could try it, will definitely get you some unwanted attention though if cops are as bad as they are in va. Got two exhaust violation tickets and I have an xpipe/straight pipe secondary/res delete. Its not even that loud...lol if anything its same as stock but more refined.

c63addix

ohhh damn, wish he had made a video. So it was loud in a bad way because it sound like an American car or Honda? lol

MaroonC63

Because it sounded like someone poked holes in the exhaust system they bought from autozone haha. But love it or hate it

If you're referring to the rear mufflers, it was my understanding that actually acted like amplifiers. Big open cambers to compensate for the sound deadening of the 4 cats...

I say don't do it... I'll be scared to play your vid when it's done.

c63addix

alright.. too many negatives about this lol! I'll just switch my xpipe on the 2ndCat to Straight pipe. not sure how much louder this will be but at least i'll get the AMG bark back

flomofo

Do cut-outs and post a video...

c63addix

BTW.. is this a muffler delete? Or just 2ndCat delete w/ straight pipe?

vanitr

Well, what is certain is that your car is going to be SUPER loud! You might like it for the first couple of hours and then the novelty will wear off almost immediately after that.

From the vid, it sounds like primary cats deleted.

That's just asking for trouble from LEOs.

I thought straight pipe is equivalent of a muffler delete? It's essentially one uninterrupted pipe from the engine. That's at least the bike world definition. The car in the video doesn't sound loud enough to be a straight pipe.

USCGTO

It'll be too loud and almost tasteless

c63addix

Well, I listened to most of you and decided not to touch the mufflers

I just switched my Xpipe to Straight pipe. Now the car runs on Straight/Straight on the res/2ndCat.

Car sounds so untamed now, but at least i got those insane AMG barks again Hopefully it'll sound a bit more tamed once the ECU adapts


Here's a sound test I just did a moment ago



The car is noticeably louder than the xpipe setup, also acceleration isn't as smooth as the Xpipe of course. But Speed-wise I don't feel any slower, probably lost a few torque ~~

I know someone who chopped the mufflers on a 2012 C63 it sounds awesome from outside of the car I don't know what it sounds like inside.

This is mine...

Awesome! sounds so clean.. Mine sounds so untamed right now because of the RAW barks and insane crackles after 3000RPM lol think i need an H pipe

I am happier with the raspy/deep note than the exotic high pitch though because it defines AMG more
