bb exhaust
Looking at exhaust and headers thinking of getting kooks to bb axle backs. Found some BB exhaust but they are only 2.5 will this make a lot of differnce from getting a 3in axle back?

3" is good for supercharged cars. It will take power away power if it is not supercharged. 2 1/2" is great for naturally aspirated cars or non supercharged cars. Great also for bigger heads and cam.
