I installed my kooks LTs last month. +1 on the 13mm flexhead ratchet. i didnt purchase one for the install, and i really should have. Some of the header bolts are a real PITA to get to and the flexhead would have been a big help. I purchased one a week ago and used it to check and tighten all the bolts, it will help you alot.

After all my blabbing, my piece of advice is just take your time and do it right like stated above. I felt a nice improvement in the low-mid range torque...oh and the sound is incredible
