So here soon all my new mods will be installed one which is the fabspeed exhaust. For the longest now I thought when
I'm corsa mode the valves stay open 100% of the time but that's not the case. They only open at 3500 rpm +. Has anyone here just went ahead & straight out took off the valves to make it open all the time? I'm thinking I could tell them to do that while installing the exhaust since this one does not have a open & close switch. Any downsides to taking the valves out 100% ???
Now I'm kind of wishing I would have got a exhaust with a remote that lets you manually open & close or use an auto mode.
