true, take note of it. i lost a fair bit of low end with the 2.5" system. but it was worth it IMO. when you are pushing it the car lives int the rev band from about 5800-8000. so it's all good for drag racing, or tracking...

lost a little bit of urge around town though. but thats doesn't worry me.
