I have the full CP-E turboback exhaust with AR DPs. It includes straight through CP-E mids (no resonators), and their axleback with a "silencer" pipe. To be honest the silencer pipe probably does nothing at all because it's really really loud. Cold starting is ungodly loud. I even set off a workmate's car alarm once cold starting at the end of the day
.
Once it's all warmed up it's reasonably tame when idling but as soon as you're on the throttle it gets pretty loud pretty quickly. Only problem is the drone/rasp between 1500 and 2500 RPMs which are likely due to the lack of any cats or resonators. Thinking of getting some resonators welded into the mids.
