You know what though... We had a similar discussion on our PCA region's facebook page. I don't know the best way to link to it...but here is a copy paste.

Robert Conyers Jr Have you dynoed your car in its current state? To gain 55hp on a NA engine of 3.4L from exhaust (minus headers, and air inlet mods) is a lot. That means your car is being choked to Hell in its current state. I'd say a maybe 25-30....only way to know is before and after on the dyno or before and after on the drag strip (trap speed).

Sudhi Ranganathan You know what David Cavazos - If after you put your mods you feel good'er when you drive, it's priceless. I suppose I will take back the Dyno recommendation. You drive on the roads and on track - not on a dyno smile emoticon If it feels good, it's good. That's all!

Robert Conyers Jr Do a before and after dyno David. That's good data for everyone to have. That's how we all learn what works and what doesn't. Just like on my Corrado. Neuspeed advertised X amount of HP gain. When I went to the strip, consistently the factory airb...See More

Brad Roberts We regularly see 50hp gains with this plenum/Cayenne V8 throttle body, real headers and using 997 3.8 Cats and high flow mufflers, but.. we tune for torque, so typically they end up around 340hp and an awesome torque curve. Someone above said: "choked ...See More

Robert Conyers Jr Nice! If big gains like that can be had, that will be awesome. I always wondered if the cars are really restricted exhaust/intake wise. I haven't changed anything on my 997.1s, but I'm curious on what real world improvements would be had from intake, exhaust & hi-flow cats.

Brad Roberts Taylor, I use a custom tune on each car by a guy who handles 20-30 pro cars in Tudor. He tunes all the BGB cars.. I had him tuning for me before he met BGB. Custom tunes, not BS generic tunes.

Taylor Stilovich I'll admit it does seem like a big increase for what the mods are. Although I suppose it does depend on what restrictions are present from the factory. I was under the impression that porsche had the cars pretty wrung out for naturally aspirated ones.

Robert Conyers Jr David, Brad did say with the addition of "real headers" & the car being tuned for all of those mods he saw that much gain. When are you getting tuned? . Tuning can make or break the car. . I want to hear the exhaust when you get it on. Will it be here in time for cars & coffee?

Michael Baynton David, I'm rooting for you, too. But I do want to see corrected before and after dyno pulls to substantiate a crank HP increase from 295 to 350-ish.

Robert Conyers Jr Yea, I heard it. Sounds awesome. He has the Fiskers or whatever they are called. I thought about doing that and having the exhaust minus the headers ceramic coated. I hate seeing the rusty/corroded exhaust.

Brad Roberts I believe I had it set for 2800rpm, right before Variocam kicks in. It's programmable. I raise it lower it as the tires and surface warm up. In another video you can hear the flat shift feature. No lift ignition interrupt upshift like a Cup car.
