I am new here and have been searching through the threads trying to find an answer to my question and it seems to be a topic of debate among Jeep enthusiast. I have a 2008 Jeep Wrangler Unlimited X with the 6 speed manual transmission. It has a brand new (remanufactured) Jasper engine and we saw that the manifolds were cracked on both sides. I know it is a box that is as aerodynamic as the broad side of a barn but I do need to replace them so I have been looking and after reading through the different reasons to get this or that I find I am just as confused as when I started. I am not looking for huge HP gains or any of that. I do have a new Magnaflow Off Road Pro Series cat back exhaust and just would like to make sure that whatever I put on will be a quality product. Every post that I have read are people arguing over whether this brand or that brand will leak and most are people looking for some kind of HP increase. I'd love any improvement in fuel economy but I am not holding y breath. I have read some people even lost HP adding certain brands of headers. This is my daily and I do wheel on the weekends when I can but what would be a good quality replacement for my manifold/headers? I am sorry for asking again but all the threads I found were just people arguing over what worked for them vs. what other people tried. I am just looking for something I can hopefully get another 250?k out of. I am an older disabled vet who just started getting into Wranglers (I still own a Cherokee and am a little more in the know with it) but the one thing I have really come to love is how it doesn't matter which one you drive, the Jeep community always comes together to help fellow Jeepers. Thank you everyone in advance and I wish everyone a great night!
