Summit wants and additional $19 on shipping because of the item size. I get free 2 day shipping from amazon and a 10% discount.

Thanks for putting my mind at ease. I will buy that tailpipe and some other stuff soon.

Going to go on my 99 4.0 with a thrush welded muffler. I already have a 2.5" spin cat on there.

I'm, hopefully, installing my header tomorrow and have a couple of questions. First, I got the black painted one and I don't believe its high heat and don't have the time to sand blast it and do a nice VHT paint job so I'm just gonna let it burn off. However, should I at least remove the paint on the parts (can't think of the name haha) that mate up to the gasket? And second, I've done my research and seems that most say no sealer on the gasket (tho some say copper spray) and I just wanted to confirm a dry gasket install. Thanks.

Oh, and here's a pic of the header.

Got a 01 XJ, muffler is bad. Thinking about a Borla Cat Back system. I know, I know, way too pricey. But I had great luck with Borla on another truck.
If not Borla, then what cat back do you recommend? Should I replace the cat while I am at it? Doesn't seem to need it. 125k miles and garage kept it's entire life
TIA,

HI All,

I'm not sure where to post my question.

I have a 2000 xj. When the head cracked, it was replaced with an 0630, I guess.

Will this affect what header pipe I use to replace the cracked one on there now?

Also, whigh one should I buy to avoid cracking again?

i have a 2001 jeep cherokee and i want one of performance curves muffler exhaust kit but i dont know which muffler would i would like i want to be able to talk to someone next to me in my jeep but i want a dodge cummins diesil sound coming out of my exhaust plus does the kit come with hangers to put it on or do i need to buy some if so which hangers

For your first question, as long as it's a head off of an HO engine, it will work just fine.

Second, look for the APN header. Stainless steel and under $200 ($160 when my dad ordered his)

My old jeep idled like a cummins. I had a Pacesetter long tube header, 2.5" pipe, Performance Curve Metallic Cat, no muffler, and a 4"x18" tip. It sounded exactly like a cummins until I gave it some gas.

Should leave the cat unless it's rusted out or failed. I live in the North east and wouldn't spend on the fancy exhaust. It's a matter of choice but I agree with basslicks, keep it reasonable.

Thanks for your reply regarding the 2000 XJ. Good to know.

I don't really know what to ask, and I might be posting out of turn, but has anyone found that a long term solution to the header pipe cranking problem?

I saw a post that some header pipes have folds or an accordion shape. Does that prevent cracking?

Thanks!

Been covered many times. Add a flex-pipe where the exhaust goes in front of the tranny.

This one kinda has a cummins growl... but it's a flowmaster super 40 and it's kinda mellow.

This one is mine... sounds a little more cummins-esque. 2.5" Coming off the downpipe into the cat, then 2.5" coming out all the way to the back... no muffler... dumps out underneath the rear bumper.

Okay, thanks for your help! Common pronlem, it serms.

Do you know please, if anyone sells a pre made set-up like the one you describe (with the flex part incorporated) that I could buy?

Is there a link to a system like that that's for sale or description of one?

I'm going to need to replace the whole exhaust system, will be taking it to a shop to have it installed, and want to do it right.

SeriousOffroad

Not that I'm aware of. The flex connector is a very common part that you can either weld or clamp in place.

Thanks Again.
