So a little present showed up today. Hopefully I'll get a chance this weekend to install and see how it awakens the sound of the beast. Below are a couple of teaser pictures. Updates to follow.

Very nice. Need a video to see how these bad boys will sound.

First impressions?

HPMan

I was able to install the exhaust but have not had a chance to take some videos. My first impressions are as follows:

1. With the valves closed, the car sounds pretty much stock. Perhaps it is 10% louder than stock (I haven't had a chance yet to test it with my sound meter). It definitely will not wake my kids or the neighbours when I leave early in the morning / come home late at night.

2. With the valves open on cold start-up, it sounds like an angry beast.

3. With the valves open at an idle, it has a nice rumble. I would say that the tone is very similar to stock, but just with more volume.

4. With the valves open and cruising, it has a very nice sound in the cabin, but not so noisy that it becomes irritating (i.e. I can definitely tell that it is not stock, but also can comfortably carry on conversations, take phone calls etc.).

5. With the valves open and at full throttle, it simply sings and really brings out the grunt of the bi-turbo 5.5 L.

Overall I'm quite happy as I like the practicality of a valved exhaust. I'll try to take some sound clips over the next few days and provide a write-up of the installation (as it was not exactly bolt on as GT Haus advertises).

Thanks so much for your impressions. Looking forward to your sound clips and install write up.

With the new exhaust, can you use the original E63 exhaust tips? Looking forward to listening to the video. Congrats!

Need4Speed

The new exhaust uses the factory E63 tips yes.

Personally I like how the Meistershaft system sounds on the E63 !

Where is the video? Don't mean to sound pushy, but really would love to hear it.

HPMan

Sorry, but my video camera packed it in. I'll have to borrow one from a buddy and try to get some decent sound shots.

How do you remove the stock E63 tips from the exhaust?

DATURK

I have it on my SL550, no open or close functionality thou, I called and asked GTHAUS that if it is going to be available for SL550's and rep said that it'll be, can't wait, but let me tell you how wonderful the sound is, when you start up first, and hit the pedal to the metal, it roars, day and night difference from the stock, I enjoy it a lot, just picked up a 2014 s63, and GTHAUS rep told me that wont be available till October, cant wait to get it....nice choice thats all I have to say, enjoy it...

HPMan

You don't.

cnolke

It comes with a new set of factory E63 tips, or you use the ones you have (and I dont know how that would work... they appear welded on)?

HPMan

2014s use the factory tips. 2012 ND 2013 replace the top AFAIK.

^^^Don't know if that guy ever showed you his exhaust but here it is on my E550. Leave a comment if you like them and enjoy your weekend

I have a GTC on my 12 e63. Tips are included. As the op stated the system is awesome. I ran high flow cats and down pipes so even louder.

My exhaust is actually for sale. pM if interested

What's the general consensus on installing this exhaust regarding the resonators (I want to keep my cats, but I like noise):

A. Keep the resonators.
B. Delete resonators, replace with straight pipes.
C. Delete resonators, replace with x-pipes.
D. Delete resonators, replace with h-pipes.

?

I just got resonator delete done and replaced it with an X pipe. Stock resonator is an H pipe. Straight pipe IMO doesn't sound very good and causes extra vibrations.

X pipe sounds very good. I still have low miles, so exhaust hasn't fully broken in yet, but it sounds very aggressive.

Stereolab42

Did you get the X pipes custom-built or did you buy one of the X pipe kits from gthaus:

http://gthaus.com/?post_type=product&s=resonator

It's not clear which one goes with this exhaust.

Stereolab42

Called gthaus, they say their midpipe kits don't fit the e63 so you have to fab your own. They suggested just sticking with the stock resonators for now and deleting later but I'm pretty sure I will want more cabin noise from what I'm told... they are clear that even with valves open it's not much louder inside (with windows up, at least). Think I will follow Anotherone's suggestion to use an x-pipe.

Stereolab42

Decided to keep the stock resonators to begin with, I can always cut them out later if it's ot loud enough. However, there is another problem... the driver's side of the damn exhaust doesn't fit. My guy says there is a length problem and one of the brackets was welded in the wrong place. He thinks this might be due to them never having tested fitment with the 2016 model year. To say I'm furious at the moment is an understatement. He thinks he can make this fit with some skilled welding, but that's going to cost me time and money. If I have to send this back I'm now out $4 grand for some unspecified period of time, and have to figure out what other aftermarket exhaust manufacturer didn't **** up in the same way with this model. What a clown show.

Stereolab42

The top is the (non-fitting) driver's side:

I would get a replacement or have company resolve. At that price point its unacceptable.

That is a **** ton of money for sound. Especially some axleback mufflers, with negligible to none power gains..... Sounds nice. Hey but if you like it....
