Personally, I would not install a Banks or Borla header unless they finally caught on and started installing the two flexible steel bellows joints where they (and the older OE headers) tend to crack. And so far, I don't think they have.

Banks and Borla headers both have a well-deserved reputation for cracking which not even their so-called lifetime warranty prevents them from needing to be replaced more often than a header with those flexible joints.

When you have a choice, buy American.

A few weeks ago the dealership had my jeep in for a free oil change. Told me my 11 year old OEM header was cracked. I letthem go ahead and install Banks header. This is a jeep dealership with labor rate about $100/hour. I got charged $450 for installation of the header, so I figure this was 4-1/2 hours labor for someone who I assume knows what they were doing. I guess you can use the 4-1/2 hours as a data point if you want to decide whether to do it yourself or have a shop do it.

Ok I finally succeed in installing the headers. Now the process is quite simple as far as the installation goes. Now with that being said let me say the R&D department placed the tubes in such a way that accessing the bolt was rather difficult. At one point I counted 6 extensions on the rachet. And don't even think about taking on this job with out several universal joints! I saved myself some money on the install but I'm not sure if I would pay someone to do the install even if though the install was somewhat tough.

Be careful when tightening the inboard most bolt next to the fire wall. It is hard to get the ratchet square on this bolt. a friend was putting a Banks on his 4.0 and broke this bolt off. We ended up pulling the head the extract the broken stud.
