APN Header install w/pics.

I know of 3 plus my own that have been on for well over a year. Mine has 20k on it and has pulled some 3k with 4 ton of trailer behind. No problems.

if you get a header - use a flexy pipe somewhere before cat to help with vibrations which crack the header - also upgrade motor mounts while you are at it

Question: Since stainless steel (factory manifold) becomes brittle when heated and cooled, which leads to cracking, is SS better that good ol' steel?

Some aftermarket header vendors use SS, others use steel. Just stuff I ponder.........

No problems w/mine... can't remember when I put it on, but it's been a good, if not great unit for the price.

does this apn header bolt right up to the stock down pipe. i have a 96 and am in need of a new header.

 

[Frank Z]

Yes it does.

Bringing up an old thread... just have one question.
Is there a design change in the 99 and up models? This apn ... (now ineedparts) model 15343 says it only supports models up to 98. Is this true and not fit on my 99?

My son's motor is a 99 and the header fits with a few dimples added stategically with a hammer.

It hits the the intake on the back cyl. Hit it with a hammer a bit and possible grind a bit off the intake. I ground a bit off of the intake it seemed like I could dent it enough to fit.

Cool. Thanks for the tips.

Interesting bringing up my old thread...

I've developed a leak (I believe) but it doesn't appear to be the header's fault, but the gasket that I used. I used the one they sent w/the APN and I should've picked up a nice Felpro and used it f/the get go. As soon as the weather warms a bit I think I'm going to pull this apart again and use the Felpro this go around.

Currently I've got 247K miles on the odometer and she's still plugging along...

Weird, never had a problem with ours.

Weird, never had a problem with ours.

Some of it might be attributed to user error as well... never could get that one bolt tight... then forgot about it. 2+ years later, apparently it burned out the gasket that came w/the APN header. Not that a Felpro is expensive... it's just time consuming to do and we've been super busy so no free time... yet. I'll take time in a few weeks to redo it and also give the APN a good look-over to see how it's holding up.

Any updates on these headers? I'm wanting to get one

 

[Redsnake]

I think you'll be happy w/your purchase. For the money they are hard to beat.

I don't have my '96 anymore... sold it ~ 2 years back but the header was still holding up well. Never pulled the header off to see if the gasket was leaking. It never got worse and my son (who started driving the XJ) never complained.

Ok...worried about cracking, but if it hold up...

As long as your motor & transmission mounts are in good shape you should be good.
