Sounds lovely, considering you have headers and zero cats.

Do you have any pics of the system underneath the car?

 

this is with 200 cell race cats.ill try to get some pictures but I installed this on jack stands and didnt bother taking any

 

before I cut up these mufflers to take out the remus resonator. Have you tried that already with just an H pipe there?

 

The H Pipe drastically mellows the tone. I wouldn't recommend it with the Remus cat-back.

Removing the remus resonators and going straight back into the cat back may actually reduce the drone.

 

did you lose a good bit of throttle response with the remus?

 

Before I installed mine I thought you guys were just whining over nothing. But now it makes complete sense. Like I told that indian kid, his video made me want those arh headers, and they actually do sound exactly like they do in this video. Now I find myself enjoying the header sound but at the same time missing the old amg sound. I personally think its the intergrated x-pipe that makes it sound higher pitched and lack of big cell cats that make it sound raspy-ish. Brutal trumpet is what comes to mind. Don't get me wrong guys, I like it, but its just different. From what it sounds like akra is the way to go to find a happy medium.

 

stock OEM resonator has an H pipe in it.

 

I was talking about x-pipe in my arh set up not the resonator mini h-pipe.

 

oh ok

well then you are already a little smother than not using an x pipe. I took my x pipe off after 2 days lol.

 

Did that help with the high pitch?

 

taking it off made it worse. I just didnt like the nascar sound.

 

Damn! Well I guess I'll look for a well priced akra in the future then. Good luck on the quest for the RIGHT sound.

 

sounds good...definitely better than a domestic...still prefer the AMG cans though.

yours sounds loud and boomy. a good combo.

 

X Pipe = higher pitched and less AMG sounding

H Pipe = good!

 

I have yet to hear any c63 in person or by video that has an x-pipe positioned anywhere in the exhaust that sounds better than a h-pipe. As others have said, the X smooths the tone and says bye bye to the AMG sound

 

Here is cold start with the leak fixed

way less boomy
