GLS63 Exhaust Question




1) I know Brabus and GT Haus make valved exhaust options. Anyone else make a valved exhaust for the GLS that I'm not aware of? Or any decent aftermarket exhaust control valve that's reliable and worthwhile? I want to make the exhaust louder but still be able to control the volume (eg when driving in the neighborhood at night).
2) I also read on here that RADO makes a DP w/ a high flow cat for the GLS63, but couldn't find it on http://world-motorsports.com. I'm leaning toward the RADO cuz I don't want the no cats exhaust smell.
TIA!




DId you fab the the X-pipe, or is it a bolt-on piece (eg Supersprint)?
How's the sound and smell with the catless DP + resonator?
smell? Barely noticeable to me vs my E55 which smelled with windows down at lights. The E didn’t have cutouts but was catless. With the exhaust so far back don’t get any real smell.
I will snap a pic and upload the cutout location later on. I have a few videos I can try to post to YouTube and share too

Open all the way they become a bit much for me. I keep them about 20% open usually unless I pull up against something to let them know this big ol SUV is quick too. I think fully opened should be a bit deeper?!?
In the acceleration vid the cutouts are open all the way.

Also anyone know where I can find the RADO high flow DP?
I paid $1595 shipped for my catless from world motorsports. The high flow cat version is about $2500. I dealt with Craig in 2017 and he even responded on a Saturday!!!

You have downpipes with this? The capristo is already installed? Does taking out the resonator result in any drone?
