Electric Cutout?

[AadosX]

Hey guys,

Right now I can't afford a cat-back exhaust system, and it may be a few months. So I was considering getting this: http://www.quicktimeperformance.com/qtec.htm

What do you think about the performance? For a turbo car (SR, stock boost for now, bov, downpipe, intake filter) is basically just having a downpipe with no exhaust just as good as having a good catback... I plan on putting this just after the downpipe? I'm sure it will be better than stock, but I wonder how it compares to a catback system such as Blitz NUR Spec R or the like.

Thanks,
John
