Awesome Appearance and Quality Welds
Time will tell about cracks and how the ceramic holds up but out of the box there is none nicer.

Nice header for 1991 Jeep
First off I have not yet had a chance to see how the header sounds and preforms as I am still in restro mode. But did install the header on the new engine that is not in the jeep yet. But wow thank goodness it wasn't in the jeep yet because there is one bolt that is a nightmare. Just install that bolt first and it will work out fine. Header looks amazing and the welds look very good and lined up with the head perfectly.

Great sound and added HP
Love this BBK header. Sound added with my Fliwmaster sounds throaty but not too loud and definitely tell the added HP. Only complaint is the middle lower bolt head hit the tubing and was a b**ch to get in and tight. Other than that piece of cake.

Great quality
First of all it looks amazing! Nice heavy construction. It bolted right up and sounds great! Most importantly it replaced the one I had with a huge crack in it.

Header install
Great fit! A little hard to get to one of the bolts on the bottom side of the header though due to design! I’m happy and would recommend!

Review shared from BBK 1-5/8-Inch Full-Length Long Tube Headers with Catted Y-Pipe; Titanium Ceramic (07-11 3.8L Jeep Wrangler JK)
nice sound
It took a bit longer than what is said time wise due I live where it rains alot and moisture is prevalent. I had cracks in both manifolds four broken bolts and two no bolt heads. I used a stud remover from napa easy piesy. one bolt stripped and I had to grind said bolt and it popped off slammed on the remover done. headers bolted right up left side no prob. left side a little fandangling and it was in poof. yes of course ran it with just the headers and man what diff. buttoned everything up and right after the Y pipe put a cherry bomb on and pipped out very throtty vey nice. also replaced ABS tire sensors both front and all 02 sensors.

Review shared from BBK O2 Sensor Wire Harness Extension Kit; Front (07-11 3.8L Jeep Wrangler JK)
O2 kit
If it is a kit it should contain all that is required not just one wire when you need 3 to do the job

Great aftermarket exhaust
Great exhaust over the OEM design. Engine was actually able to breathe. Sounds and feels great. Installation was pretty straight forward. Only issue real I had is there weren't enough O2 sensor extensions included, I had to buy two more. Your check engine light will be on because of the deletion of two cats (at least for an 08 model) and high flow design of the two cats on the y-pipe.

Handles the salt
Good fit and install for the most part. The headers get close enough to the transmission that it's nearly impossible to remove sensor 2 in bank 2. Passenger side
