Haleyrz XJ Build - Page 6

Yeah I was considering the rugged ridge or pacesetter. Kolak advised me against the pacesetter because they are similar to the stock being thin and prone to cracking. I'm not sure on the RR headers. The price is awesome, but kind of seems too good to be true. I'll probably just have my roommate throw some weld and seal the crack for now until I can afford either the banks, edlebrock, or doug thorleys from Kolak. Duff, did you notice any performance increase from the RR headers?

I've noticed I get alot better throttle response (before anyone goes off on any "placebo effects", I'm also a performance car junkie, I know about throttle response) and I'm actually pulling alot better gas mileage around town after I put them on.

They seem to be pretty high quality, on par with hooker and edelbrock, in both fit and craftsmanship, I'd recommend them if you need a good replacement/upgrade.

I think i'll go against all odds and save for the pacesetter. From an engineering stand point, their design looks pretty decent, and I like the fact that they come with the downpipe and collect to 2.5". According to summit's site they are made of the same grade steel as banks, but the flange is a little thinner. Price isn't bad. Just a tad over the RR headers, but come full length. What do you guys think?

I think headers are a waste of money outside of carbureted hot rods. The major downside, other than price: they make everything involving spark plugs more difficult. To me, the money for them would be better spent on aftermarket speakers, the BB, a lunchbox locker, a front or rear receiver, recovery gear, etc. If you want more power, I'd do lower gears or go for a power programmer way before I ever thought about headers.

So having an exhaust with a more efficient design than from the factory is bad? And what does that have to do with spark plugs? Seriously...

I see your point because any performance gain will be minimal but I don't agree. If your manifold is cracked(like Haley's) there is no sense in replacing it with another manifold knowing it is a weak spot.

power programmers are most effective in diesel engines and dont do jack to jeeps! i got to try one out at 4 wheel parts once and had 30 day money back if i wasnt completely satisied and it either makes your engine chug gas or takes all the power from the engine to make it economic they are worthless.

My dad has one for his f 350 and that makes a big diff on gas gained 13 MPG and the trcuk still has alot of balls id say enough to pull something very consistant and it still barely even feels the load!

now when he tunes it to power mode that think will burn out at every red light with an easy tap of the gas! its insane but sont waste your money on power programers they are originally made to by pass codes and diesel engines! id say for power go with the full headers i think you seam to know what your going for. you should also get an intake tho so yor engine has the right amount of input as it does output for the exhaust!
If you have extra cash sometime i would either bore out the throttle body or just get a bigger one talk to Kolak on those he has what you need!

I didn't say it was bad, just that it wasn't the first place I'd spend money. And as far as spark plugs, it's late and I'm tired. I'm thinking of GM 90° blocks. I forget about having an I6 in the Jeep with a completely different configuration. It makes sense if you could read my mind and know I was thinking about a Chevy 350 with headers and all the ghetto rigging I see people do to keep the boots and wires off of the hot pipes. Anyway, back to your regularly scheduled problems.

The better factory manifolds can be had for much cheaper though.

It was just an example...and a guess. Never used one on a 4.0 but I've seen good results on Dodge 318s and Ford 5.4s. I have a Hypertech chip in my old TBI 350 that makes a big difference. I figured they'd help with anything.

nelson1248 · 10-06-2009, 12:03 AM

well i guess it wouldnt hurt for ou to try it out you should go to your local 4wheelparts store and see if they give you a 30 day money back i not completely satisfied deal and see if it works on the 4.0 but i have the H.O and man it sucked wouldnt hurt to try to since we have different blocks you know!

Haleyrz · 10-06-2009, 12:07 AM

Whoa...ok. First off, headers have benefits when put on full systems, just like you only see benefits with CAI's when you have a full system on. I know this. Performance gains interests me, but will be had when money allows. I know there are more important things to do. Also, my idea of what needs to be done first is different than someone elses. Lots of people have huge jeeps built up and are mega trail crawlers and want lifts and recovery first. Me, I'm a very mild wheeler, and this is my DD, my only vehicle, so I see performance, efficiency and economy as more important than lifts and recovery. I'd love a huge *** jeep just like the next person....but I'd also like to keep things realistic and practical. That being said, the exhaust, headers, upkeep, and keeping things running smoothly while my new found non college life in order is what I'm going for right now. As for programmers, I wasn't talking about them but if done right, and you have the right programmer, you will see benefits. In fact, exhausts, intakes, throttle bodies, thermostats, all that will be minimal without the proper programmer. Thats the problem I see with all modern engines. Its just a matter of doing the correct research on all the companies whos products you buy. Thats my opinion anyways.

nelson1248 · 10-06-2009, 12:14 AM

money talks and bull **** walks! i wish i had the money and i know lots of us wish we did and some have the money to back it up! im in college and seak high MPG my next step is regear then comes the engine mods! the rest of my build is gonna take time and not gonna move as fast as it did this summer but things need to get done right so slow is the way to go.

Haley you seem to have your head straight so you seem to be on the right track! just follow what ever build thread your following but know what your main goal is and do things once and do them right i know thats where most guys on here end up spending more money is by doing things over and over till they finally get it right.
Id say your doin a good job!!!

i hope your BF helped you with your build sheet your going by! lol

Haleyrz · 10-06-2009, 12:27 AM

Not too much, everything is really my decision. My boyfriend wants me to get the banks headers cuz thats what he has, a 3-4" lift and 33's, but he wants me to do it all at once. Well I dont make $30,000 a year like he does, I make $10k-$12k a year if i'm lucky. Mainly cuz of college but now cuz of the market. **** this economy, lol. I graduated in interior design and there is NOTHING so I'm stuck at Autozone/retail until further notice. I take care of looks and maintanence though. For example, the tail lights will get tinted but leave the backups white, the white sidewalls on the new tires will be out, and the amber corners will become clear. The future holds an OME kit and stabilizer and a yellow top battery, so I'll have this whole green/black/white thing going on the outside with bright yellow accents. The boyfriend is a mechanical engineer, and really helps me when I need things explained by their design. He's got some bumper designs drawn up. Our roommate is the deisel mechanic graduate that has all the tools. Together the three of us will get the jeep to awesomeness. Thanks again nelly! Whats going to be in the future for you dub performance wise?

Glasses push* Neato!

nelson1248 · 10-06-2009, 12:38 AM

damn im so jelous you have eveything you need a discount at the autoparts store a mechanic to explain stuff and extra hands and a diesel engineer! what else could you ask for! lol

Ya X2 on the economy its a *****!

well im trying to save up some money to regear im starting this new job at t mobile next monday! (WAHOO!!!)
after that i wanna get a bigger throttle body Intake and run either a 44 or 50 series flowmaster with 3" piping all the way back and after that get a steel bumper a winch and i think my rig will be done setting me back 3 grand

I havent decided if i wanna run a cat yet tho. my friend has a mustang and got some sort of sensor bypass so the check engine light doesnt turn on with out the sensors being plugged in and he passed emissions and our emissions are pretty strict so i think i might do that i havent decided either that or a high flow cat!

I been thinking tho, would it help my performance if i just ran from the end of the heads a pipe and a 44 on each header would it be any different than if i just ran 1 the 3" piping all the way back! this would pretty much give me true dual exhaust so you guys understand my concept?

Luke94XJ · 10-06-2009, 12:52 AM

yeah duals would be better, but you may want to run an x pipe, it also keeps a vehicle that didn't come from the factory with duals on the road.
