Anyone hear about this exhaust header?

[Jeepcrush4]

Mine are stock and looking to need a replacement soon. Not expecting huge gains, just longevity and dependability. Can't afford to coat them so I just wanna throw them in. Are these a good design?

looks like an apn

[seanyb505]

Same as APN but you can get them cheaper: http://www.ineedparts.com/auto-parts/exhaust-parts/exhaust-manifolds/jeep-exhaust-manifold.html

Ive had mine for about 3 years now, no cracks. Same as Banks I believe. If you have the 99+ intake manifold you may need to do a little clearancing on the #6 tube

I'm guessing header gasket is seperate? My xj is 97. Hope it goes well.

[Jeepcrush4]

N/m thank you sir'

The APN comes with a gasket (single gasket for both manifolds), but I'd say spend a few bucks and get a Felpro or such.

I've been running the apn header with the supplied gasket for a while now and have had no issues with it.

Tube gauge is not listed but should lasted as long as the rest of the jeep anyway.
The only bitch is that they are longer tube then some. With a longer tube more heat can build up under the hood. A problem for some offers without vented hoods.

I bought one over a year ago nice upgrade for the money. Good warranty also.

[Jeepcrush4]

Do you recall the necessary type tools to replace? SizE sockets, deep/short etc. Reason I ask is because I'm sort of limited on tools and the parts store is a good 5 miles away and I don't want to get stuck because of one tool I didn't have. Thanks in advance.

14mm socket and 14mm ratchet wrench. Remove airbox to get perpendicular to bolts in middle underneath using a couple extensions. Use pb on the header/downpipe junction. Disco fuel rail and tb linkage bracket(10mmx3) to move intake manifold. Careful when pulling off vacuum hoses. CKP is bolted to rear most fuel rail mount.

Are the exh mani bolts known to break? Any other problems to watch out for? Trying to determine if its better to take to a shop and have them do it.

[gradon]

The bolts, no, but the studs on the ends with the nuts and the bolts @ the header-downpipe junction, yes, so use a little wire brush to remove any rust from the threads and pb them up good before you remove them(if the nuts start to get difficult once loosened, tighten a little bit, wipe, and respray some pb). Clean out the intake manifold and in/ex ports once the manis are removed using carb/tb cleaner and a small nylon brush or old hard toothbrush(don't want metal bristles to get in the chamber or cylinder). You are more than capable of handling this job.

There's one that my friend got for his YJ that has flexible segments, to prevent cracking.

[hawk_sixsix]

I have a 97 XJ with a custom 2-1/2" welded mandrel exhaust from the manifold back. OE manifold is fine - no cracks.

1. Is this a worthwhile upgrade, performance-wise?

2. Does this bolt directly to the stock [location] downpipe?

[Johnnie Walker]

Should bolt in fine, Not as prone to cracking as stock manifolds. Disipates heat better, and sure a slight gain in power will happen.

This will fit on a 2000?

[aparke4]

2000-2001 has different 02 sensor locations - let me check

also, good time to investigate and replace if needed motor mounts. i did a banks header on my 99 and 1 month later put in more poly mounts. checked header the other day and no signs of leaks or cracks. if you have a worn out motor mount then change it out while doing the header! oh and if u do not take manifold off/ out - then there will be one bolt that will be impossible to cinch down - unless you have a double jointed midget - not enough room to tighten so u have to take manifold off to get to every bolt. do this anyways - makes job so much easier!

I just put one on my '98 this week, no problems except you can't torque one of the bottom middle bolts, oh well. And who cares if the pipe bolts break cause they give you new ones.(both gaskets and pipe bolts & nuts) I'm waiting for other new parts to try it out. Good Luck!!!
