Question Any experience with exhaust valve modules (e.g. RENNtech EVM)?

Hi all,

I was wondering if anybody had any experiences with exhaust valve modules, such as the one RENNtech sells?

RENNtech claims that upon device removal, it would be impossible to detect that this was ever present/used (i.e. it will not interfere with warranty as long as it is removed prior to a dealer visit). Can anybody corroborate this?

It seems like a great product and it would make a significant positive change, but not if there's the slightest chance that it could impact my warranty after it is removed.

Thanks in advance.

I’ve had the Weistec one installed on the driver side (passenger side is a pain to install so I haven’t done it yet) and my dealer doesn’t seem to notice or care when I take it in for service.

RENNtech is now telling me that their's isn't compatible with my car. Do you have a C450? Which product are you referring to? Do you like it?
