Great, thanks. I'm between this, the Cleib, and the Greddy SE dual.

Having owned both the 70ssp and 70em single they are both very similar at idle and low rpm/light throttle. From there the 70ssp starts to get louder/raspier. The 70ssp isn't much louder at WOT but IMO it was a lot raspier than the 70em single. 70em single also sounded a lot better at part throttle. Both were run with a TP.

I found that with a HFC and/or TP it even had a little more rasp at 4-6k rpm in part throttle than I'd like. Now my car at the time also had a rollbar with the rear interior gutted so maybe everything just sounded that much louder to me but I was disappointed. I think the EVS looks better than the 70em single but just doesn't match the sound quality. If you know you'll keep the stock cat the EVS70 was perfect.
