Depends on what kind of dyno and what shape the car is in, 300 would be my guess.

Jetstream Blue Metallic- 2008 Z06 Corvette
Let's do the math..325Hp to start at the crank. A typical loss of 50 HP for a manual trans, a little more for a auto to the rear wheels. So for the sake of argueing, let's say you're starting with 270RWHP. Okay, let's add up the goodies now: SLP Lid (I did the whole cold air system, so I'll assume you did too) add 8 HP, forget what they say. Smooth bellow: add 2HP at best (don't get mad at me, I bought one too) TB by-pass add zero HP. My best RWHP guess:...280RWHP If SLP could get sued for inflationary advertising, they'd be out of business. But, they do make a quality product, and in spite of the fact that I do know they inflate their claims, I purchase their products almost exclusively for my Camaro too. make sure you have quality gas in your car for the pull. It does make a differance!

In case you thought I forgot about the Flowmaster, I didn't...the average Flowmaster owner LOSES 2HP...Sorry and yes, before I did redid my entire exhaust system, I had one of those too.

Okay my estimates may be a little on the high side. After thoughtful consideration I will revise my guesses to be 315 at the wheels and 346 at the flywheel.
