Default Performance upgrades!

So right now my 97 cherokee is about to get alot of upgrades/ make over.

It is currently sitting on 31/10.50/R15 bfg km2s, rough country 3 inch lift, spectre air filter, and 2.5" exhaust with a cherry bomb.


My manifold is cracked and sounds like crap. so i wanted to buy a header for it just dont know which one to go with right now...Been searching ebay.

Next i want to add a bored out tb from thexjfiles.

Then 703 injectors from programbo.

Is this pretty much all the upgrades that i can do (cheaply)

this is gonna sound like a dumb question, but what is the difference between headers and the manifold?

That is just a replacement manifold and not a header, but will work fine.
I recommend a bored TB from strokedjeep.com
A 99+ intake would help as well.

More air flow which mean more hp is what i was told.


I was gona buy a header for my jeep only cause my stock manifold is cracked. But a guy told me to buy this one because "Many XJ owners will tell you that a more practical exhaust manifold replacement with built in "flex" points that account for thermal expansion and contraction (reason why the oem and many solid tube headers crack to begin with.)"

So that is why i am asking about this. as for performance i but a bored tb from this guy on here his name is thexjfiles its a 60mm bored tb.

more air at one component will not show gain, you must go I/H/E to see real gain

So my cold air intake, bored tb, 2.5" exhaust, and 703 injectors should be good?

i dont know if were allowed to talk about clean cats or straight pipes on here, but yeah i would expect to see decent improvement. esp since your getting rid of a cracked manifold, run smoother and all, dont forget to reset ecu, it needs to learn its new way of breathing.
