which catback would be best?
You can run all the parts w/o a tune. If you want to maximize the performance I would highly recommend a tune. Just bolting on the parts we gained around 90 whp with full bolt ons. Once tuned the torque number / throttle response jumped dramatically.
The 4.0' will fit behind the crash beam. On the back side the crash beam there is a bracket held on by 2 rivets. You can either drill the rivets and remove the bracket or hammer the bracket forward to clear the intercooler. The 3.0" and 3.5" will fit with the bracket in place.
Hope this helps!
