STG, you know were talking 991.2 here right? I know all you 991.1 guys are sort of hand cuffed with the N/A motor for additional power but Looks like 32 hp according to Fabspeeds dyno chart on the .2S model. Most other manufactures are claiming similar gains with a full exhaust. I think I'll spend the $7K on an exhaust and Cobb tune and have a 3 times the power gain. http://www.fabspeed.com/blog/develop...12-carrera-4s/

I'm a huge skeptic on horsepower claims -- but it really is true that on turbo cars, you can get huge gains from software. Just turn up the boost. Crazy to spend $7K on a factory "powerkit" that only gives you a few hp when you can flash the ECU for pennies on the dollar. Just make sure the new software is from a reputable place.
Options are a cash cow for Porsche. Their profit on the $7K "powerkit," conservatively speaking, is probably $6,950.

Also, you guys do know you get 3mm bigger turbos with the power kit as well right? Thats a lot more than just a new exhaust...but even still on turbo cars even without a tune it makes a pretty big deal. Also, porsche can't or wont to 200 cell cats on street cars as per the EPA, thats really where the HP comes from with any of these aftermarket exhausts, which almost ALL use HJS cats. Btw that and and an xpipe you're looking at a pretty easy 35 (well call it crank to be safe) hp to add onto the already super robust 450 (with power kit).

When you back out all the other options that come in the PowerKit package, it's more like $5,500 for the additional HP. I'd to the PowerKit before I'd go aftermarket myself, but to each his own. I just wish there was an option to do the powerkit without the sport exhaust.
