That really all depends on your end plans for the car and what kind of driving you do.
More important then size, you will see the most gains by going with an off-road mid pipe like the MAC Off-road Pro Chamber Mid-Pipe
The mac combines both the X pipe and H pipe design and provides a unique sound while making some power!
Hope this helps and let me know if you have any questions!
