Got it.
No such button on the older version so anyone who upgrades to the Akrapovic would have to buy the option remote control is my guess...or does the system allow you to just leave it in the open position permanently?
So on your new exhaust there is an electrical connection or plug somewhere that has to be connected for a motor to physically control opening and closing of the valves ?
How do you open and close the valves ?
Through a remote control that I see on their website as an option ?
What if you did not buy or have that remote, how would the valves be controlled ?
Just want to clarify things a little here. The exhaust button inside the car isn't an all-open or all-closed setting. It's basically the exhaust version of comfort vs sport +. So with the exhaust button turned off, valves are mostly in the closed position. With the exhaust button ON, the system opens the valves up alot more which creates alot more sound and gurgling and bangs. The difference between the "button" and something like an ASR controller is the controller lets you have ultimate control. Fully closed, fully open or leave as the way the console button works. Without the valve controller, you cannot keep them closed all the time or opened all the time. I have my c43 on "open" at all times and never need to use the console button ever.
Great explanation.
To keep things simple and fail safe, I would want the open at all times mode like you had on your car. What is the the point of turning down the volume of the exhaust after spending the money and time to modify it 😁
When you say too good of deal @2820G63 , can you share where you got the Akrapovic exhaust!?!?!?!
OP purchased them from @CClement who had purchased them from me. By the time it reached Craig (CClement) he didn't need them any longer so he sold them brand new at a reduced cost. I have special deals for all MB World members on the Akrapovic exhaust.
@mrtonyn The Akrapovic mufflers (named Evolution Lines) shed 30+ lbs over the factory mufflers. To swap these in only a few clamps & bolts are removed; no cutting or welding involved. For the Akrapovic downpipes (named Front Link Pipe Set) cutting of the factory downpipes are required just so that they slide out of the engine bay. These would have to be welded back together if the SUV ever needs yo be put back to stock.
In the video below we did a combination of Akra muffler, DME Tune, & Renntech downpipes. Our client chose Renntech because at the time the Akra downpipes were months out. These mods resulted in 150+ hp & ft-lbs. I have package deals for those interested in these mods.
So if I just replace with Akrapovic mufflers and DME tune, how much HP and torque gain ?
Besides additional power gain with the downpipes installed, what is the sound difference between with and without installing the downpipes?
Thanks
Just a tad over 100 hp & ft-lbs of torque.
Upgrading the downpipes gives you much more power than upgrading the mufflers. From a sound perspective, the mufflers add more grunt & decibals to the overall sound level. The downpipes would add the turbo spools & whistles. If you're doing one of the two & accompanying it with the tune then there's not much reason not to do the other.
LOVE those! Looks GREAT I was REALLY debating this or the iPE and heavily leaning toward the iPE.
I got sidetracked by the holidays/new year and then getting rear ended but now Im finally ready to pull the trigger and make this happen already.
Did you consider the iPE? I can't recall exactly which model I was looking at but it was not just the mufflers but would not require a tune.
Hi guys. Here is a photo of my G63 with the akrapovic exhaust installed the tips were painted matte black! Bought the entire system from Craig (thank you Craig!!)
Here is a link to the sound clip I posted it on YouTube, it’s short I’ll take a better one later:
For clarity, you're only running a lite tune and the Akra slip on mufflers.... No front link pipe and no "Akra Sound Kit" module?
I have the option right now to buy the slip on mufflers used. The last owner had the sound kit as well. It looks like a lot of work to install the sound kit vs just slipping on the mufflers. Trying to find folks that have one or both and get sound clips has been challenging. Any insight from your experience would be great!
