There's a vid on youtube posted by IPE for gle53. I would say what you hear from the vid is not 100% accurate tho. That car was downpipe. So the tone is higher than catback.

I have my gle53 go with IPE. At the time I was deciding between Armytrix/Capristo (dont know if capristo do the GLE53 but I heard it installed in E53, very good in high pitch tone) and IPE.

Armytrix seems to be good in higher tone only, no body in the sound. I dont think it suits my SUV tho hahh.

It was about go "Vhaaaaaddddd" or go " Vhooommmm"

IPE is gentle sporty grown man! That would be my experience.
