I don't have a dyno but I have a decent feel for my car. I put 5K on it before I modded it. I installed a Topspeed CBE and it it felt a little better. Still rather quiet but a nice deep tone. A couple weeks later (Sunday night) I installed a T/S y pipe and Surewin (cheap ebay) test pipes. It is much louder and kinda of fart can sounding over 3K rpm. I haven't really ripped on to see how much it changed, but I lights up the VDC light on gear changes like it did stock in the winter. I have sport tires and it was 107 F today. The sport tires are not very tacky in single digits.

I also went from averaging 20-21 mpg/tank stock
23ish just T/S CBE
now with 1/4 tank burned I am hovering around 24.
