I am installing this on my car this next Saturday (10-8-16), I'll let you know how it goes.
I checked with the dealership (Service Manager & Finance Manager), the only element of the warranty which becomes void is the 2nd set of catalytic converters, and associated exhaust piping. No impact to anything else, (got it in writing).
As well, I am trying to get onto a dyno, both before and after, as the gains are quite large (7-10% hp). I know a couple of the guys at Borla and when I asked about the system (#12671), they were very confident in the gains.
If I get the dyno sheets, I'll post them for you, if not I'll shoot over some pics if you like.
Unless you already bought this for your car . . . in which case "what do you think"?
