I just found out there is a company that makes a valvetronic exhaust for the GLS63 AMG. Xpipe design which is nice. Price is very reasonable too at $2500. Follow them on IG at : etunfab
Can't wait to hear the beast after a DME tune and this muffler!
Would think the X pipe would be a detriment to a turbocharged engine since there is no exhaust scaveging going on. As far as the sound, do you like it more?

The Xpipe I have on the car now made a significant difference in sound. The thing is that this etun miffler is an Xpipe already so I would have a double Xpipe system. I might just straight pipe where the resonator was and have the valvetronic Xpipe muffler as is. If you look at turbo Mclaren and Huracans, they are using Xpipe designs for exhaust so no I don’t think running an Xpipe on a turbo car is detrimental to the car.
Must be an exhaust quieting or sound improving device if anyone is using on a turbocharged vehicle. Just no other benefits to it as far as I understand how the exhaust works in a turbocharged engine. There is a benefit on a NA car since it can help with scavenging and equalizing the pressure between sides.
Huracan is NA so I get that. With McClaren, must be to help meet db requirements. Are you saying McLaren has an X pipe from the factory? Would like to know more.

I did some reading up on running a Xpipe on a turbocharged car. You are correct man in that it is basically pointless to run one with a turbo car. I’ll be straight piping it when I get back from Tokyo. Thank you for clearing that up for me. Mclaren don’t have factory xpipes but most of the aftermarket systems offered for them are Xpipe setups. My exhaust from ETun will take 2-3 weeks to make them I have to wait another 3-4 weeks for it to arrive in the US. Can’t wait to hear it with my new setup and tune. Also, are burble tunes really detrimental to the engine in the long run? Thanks for your time BlownV8!
What some do with X pipes is remove the mufflers but, from what I understand, the X pipes do cost a turbocharged engine some power in the rpm range so they would be a no go for me if you are trying to make the GL faster. On the burble tune, for me, I would not run since you could cause issues with the O2 sensors and catalytic converters.
On exhaust, I would remove the rear mufflers and straight pipe all the way back to free up the flow. With a turbocharged engine, you want the most free flowing exhaust as possible with no restrictions to.make the most power.

I want to be able to adjust the sound on the fly so I can make it loud when I want it and quiet for long drives with the family. So I'll be doing the Etun Muffler and straight pipe where the resonator used to be. I have so many people contacting me to buy their tune and don't know which one to go with. Weistec, OE Tuning, EC, and DME. I've seen many cars recently tuned by DME with great results. It seems they are squeezing out the most power out of the M157. Id like more power but I want a tune that will keep the car reliable later along the road. I heard Weistec recommends you to change the spark plugs out with colder ones. It weird because none of the other tuners require this upgrade. Anyone here have a DME tuned AMG? Let me know how you feel about it. Thanks
The just straight piped where my Xpipe used to be and it feels a lot faster and sounds way better! I might not even get the muffler anymore as it sounds pretty aggressive already. Well see in the near future! Thank you BlownV8 for letting me know turbo cars don’t need xpipes!
The stock resonator is an H pipe setup. I just simply removed it for true H, added catless downpours and then elec cut outs. The cutouts are controlled via the home link buttons.
OE tuning here with burble. He tunes the timing different vs dumping fuel so you don’t burn out your cats. I have 5 maps so can change as I please.
and yes, no x pipe for turbos unless you want to quiet the exhaust. I have straight through to muffler.
zero issues.
I went with DME tuning stage 2 tune. And the car is transformed now into a beast! Drivability has greatly improved as well in all driving modes! Couldn’t be happier with DME tuning! As you know they are the leader of tuning pure turbo cars on Mclaren, BMW, and AMG. Check them out and you won’t be disappointed.

Resonator delete alone sounds epic already! I can’t imagine no mufflers.
