APN or Dorman exhaust manifold?

Guys, I want to replace my exhaust manifold on my 1998 XJ with 200K (I'm doing motor mounts as well) and am torn between using a Dorman or an APN. I don't off road much, but I like squeezing all the power I can out of the Jeep for the interstate...

Anyhow, here are the pics:

APN:




Dorman:

APN. Google APN or use the Forum search function. I have installed 2 APN on my Jeep fleet so far.

I think the flex-pipe is a good idea and will probably be installed on my next APN project.

The APN manifolds are nice. I personally went with the Dorman because I got one brand new for $110 shipped on ebay. Haven't had any problems with it.

I have not had an APN header but a Thorsen header I bought cracked in about a year. The Dorman manifold I have now (like your picture) is the only exhaust mainfold I have ever put on the XJ which has not cracked.

Dunno if they'll fit - the APN looks like it's twice as big as the Dorman.

Which "flex pipe deal" is that? Replace a section of hard exhaust with a matching flex pipe? That was on my to-do list with my last 96 XJ (http://www.yuccaman.com/jeep/whitejeep.html) and was on the to-do for the current one, but now I'm thinking of selling and getting an '06 LJ Unlimited instead...

APN worked for me, but I did have to do a fair bit of "adjusting" to get it to fit in with the intake manifold.

I've heard a little here and there on the injectors, are they a bolt-on affair for a '93 as well? Worthwhile investment?

Stang man, I'll let u know... one thing though is i wasn't able to clean the neon ones, i hope that doesn't effect them much. from what i've read (and i've read tons on the subject), it's a mixed bag on results, pretty much. sort of like political discourse, you kind of pick out the posts that agree with the way you want it to be like :-)

well i drove my xj with the new brown dog motor mounts and new oem transmission mounts tonight, definitely like the feel of it. it feels like it has more power to me and maybe its louder... one of my old mounts was broken too, so thanks for the always good JF advice on that. i got the rubber brown dogs, now, because i like the feel of it, i kind of wishing i had gotten poly. anyhow, the takeaway from this blurb if you are reading it is that motor mounts make the jeep feel better, like a hot rod ;-)

Loved the '99 manifold in my '96. I went with F5TE-24lb injectors from Fiveomotorsport.com (hope I can make that link without violating rulez) with that as well.
