I'll end up buying a Cobb XLE premature only because I know I'll be rotated in the next say two years. I'd rather a well built BPV than to push the limits of my plastic stocker.
I've ran HKS SSQV V3- sucked and leaked and a poor decision for my car
Also ran TurboXS RFL- sucked and very hurtful for my car, also leaked.
Also had a TurboSmart- came on my 04 that my wife bought me, too loud, but preformed as it should have. That car was also front mounted and was owned by someone who worked at PSiProformance, a local tuner. So it was more than likely adjusted with its spring the correct way "".
I sold that to a young kid and used the money to get a Cobb XLE which performed exactly as it should have right out of the box.
I'll stand behind Cobb products, they are very well built.
But I will not suggest going aftermarket unless it's due to higher end performance.
