OP, let us know if you notice any change in sound after installing that X-pipe tip outlet, I am genuinely curious to hear your thoughts. Zentrickster, you can call anytime if you'd like to talk in more detail Evan 267-818-3203I recently installed a Softronics flash on my 07 Cayman base model.. While the 2.7 will never provide monster power. The flash did wake up the car, and it feels more powerful acroos the operating range.. Also the Softgronic customer support is top notch. Next is a soul cat back exhaust..
