yea i saw some people saying that the black paint was only for shipping purposes. but thats not a problem. i was just going to strip the black paint off and paint them with 2000 degree high heat header paint. for the price, considering it comes with the entire downpipe to the cat....i think its a good deal

I have the Pacesetter on mine. I stripped the entire thing and did a high heat finish. I did my research first and decided it was the best deal for me. Only issue I had was the gasket that comes with it has to be trimmed for the 99 head and the surface needed a little grinding to take out some pitting. Mine sealed up fine and paired well with my intake and ford injectors. Just make sure to get some heat shrink butt end connectors for the o2 sensor relocation.

And for the price, if you can fix the rusting issue by stripping it and re-painting, then that sounds like a good way to go!
Let us know how you like those and any downfalls as well.
Good luck

How do you like that brand?
Notice an increase in HP/torque?
Any input will help the next guy!

Got my new APN header on last night... The OE header was cracked in multiple locations as expected, not to mention the rubber isolator inside of the driverside motormount was almost completely gone, so I replaced that while I was at it. Not complaining though, after 20 years of wear and tear. The APN header design is definitely more flow friendly which is obvious right out of the box, but I'm going to have to drive it some more to give an accurate assessment. Shooting from the hip... she definitely feels/sounds stronger, but that should translate into better MPG. We shall see.
are they really worth it? if so whats the best brand to buy that gives you best bang for your buck? i have a 99 xj and im tossing a new engine in it, and slightly building the new one and figure this is a good spot to look into. any opinions/thoughts would be great! thanks

No worries, I was just going to comment on how urethane mounts are much stiffer and will transfer vibrations to the chassis a lot easier. But they'll also hold better. So if its a dd id recommend doing stock ones if not then its purely choice

I have a 98 XJ and I'm looking for a new header. I picking up an intake manifold from a 99+ XJ this Friday. Has anyone swapped out there's like I am doing and put an aftermarket header on? If so, what brand, price, and problems encountered. Thank you
