Of course it is always important to use the same car. None the less, I did drive Curts car before and after the BPM TT install. It felt like something on the order of perhaps 10 or 15 HP. It didn't feel like 30-40. The spoolup was noticable, and 1st and 2nd seemed to benifit the most. I remember driving his car about a month earlier, and it seems comparable to my car. (this is before the TT install).

TurboXS' web page says it well:
"Dyno results with this kit installed showed that our WRX made 210hp at the wheels vs 180hp stock and a peak torque of 216ft-lbs vs. 192 ft-lbs stock. This is a 17% peak HP gain and 13% peak torque gain. Since we do not know true engine HP, we can only estimate peak crank horsepower at approximately 265 horsepower and peak torque at 243 ft-lbs. "

They are seeing about 17% with the chip and partial exhaust. We saw about 15% +/-, and there is some error since the baseline was a different car. None the less, the same ballpark. I don't think bolting on an exhaust, no matter what kind is going to give you more than 10-15%, perhaps 15-20% with a boost controller. If you really want power, get the larger turbo and the exhaust.

I don't think this is a bash on BPM in any way. I like the exhaust, it performed as I would expect, sounds great, and is well built.
