Headers will give you better airflow and which means a little more HP. I don't think you will even notice the gains too much but you should a little. JBA headers are popular and cost approx. $400 for our engine. Unless your stock headers are falling off I wouldn't invest in getting new performance headers because when you look at the price per HP it's almost nothing.

And oh yea, if you look back through the forum there is a thread titled "headers" that I recall and that should help you out. I will try to look back and find it so I can post you the link.

Do NOT get the JBA headers... there is a MUCH better set of headers for way cheaper.

JBA headers are unequal length headers. MAC Headers are equal length and will out perfrom the JBA's, and they are $300 for a set.

www.macperformance.com
You have to call them to get them made for you. Trust me, they are worth it. Gains are typical from about 8 - 10 rear wheel horsepower. VERY NICE for a set of Headers for a V6.

Sorry homer, didn't mean to bust on the JBA's, but the MAC's own 4 real.

Homer is right about headers. The quicker and more efficient the airflow is throughout your engine, the more power you'll get. Headers are top dog for getting this done. Now if you combine a set of Headers, a full Intake, and a full Exhaust, you're talking 20+ rwhp and that's without a chip. Add the chip, and your V6 will be running much faster than stock. Also, the more mods you have, the better you headers will perform...just a rule of thumb.

Also, the MAC headers are eventually going to come out with Long Tube headers, but probably not until mid 2005 or so. Long Tubes will kill the shorties any day. I'd say 5 - 6 + rwhp over shorties.

Awesome info Joe!

I really think I am going to invest in the long tube headers when they come out. Until then I'm stuck with my rust INCASED shorty stocks and my sideout exhaust which is already old to me and I've only had for 3 months! im sad..

When those new ones come out I'm planning on getting a full new exhaust system...
The long tubed headers
high flow cats
and a flowmaster dual exhaust


For now I think I will soon be getting dual exhaust on my truck so it looks better, the sideouts just dont fit me...

Joe, or anyone.......answer this for me

I've got no muffler and just cat back single pipe...do you think if i add a flowmaster muffler (not the full exhaust system, just muffler) into my future planned dual exhaust package--do you think the sound will be better than what it is now?

I'd have to hear both to decide. The muffler will make it quieter for sure. Not a LOT quieter, but right now I'm sure with no muffler you've got a pretty nice rumble going on. If you can take it, I'd just save the money and stick with no muffler.

Nope, I have heard that a longer 40 series flowmaster make the 4.2 almost sound like a v8.

Nope, not nearly as deep as the V8. My Flow 40 series muffler has a nice rumble and is 'fairly' deep in the lower RPM's, but once I get going into the higher RPM range, the rice starts coming out ever so faintly.

Joe,

Do you have anything to back up these statements? Did you know that the reason the MACs are so cheap is because the ceramic coating they use cracks and flakes off? There is a reason why JBAs are pricey - you get what you pay for. Do more research on the MACs, and you will see lots of people love em, and some people are wondering why the coating is falling apart.

Until someone shows me actual performance numbers on the EXACT same setup - IE, you put both sets on during dyno pulls - I dont think it's fair to say one is better than the other. What IS fair, though, IMHO, is to say anything is better than stock! Just my $.02

Garrett

Okay, not to bring a big discussion into the mix, but is it not obvious that equal length headers will bring more performance than unequal length headers? That's just an obvious fact to me. Now then, they may not produce a lot more power than the JBA's, but they should (in theory based on obvious evidence) produce more power.

It's like this...long tube headers produce moer power than shorty headers any day. In the same way, EL headers beat UEL headers any day. That's just my thinking of it just like most others.

Also, if you do research on both sets of headers, I believe the JBA's have more of a problem than the MAC's do. When I get my headers in and installed I will *try* to get a dyno pull number on RWHP difference. I'll dyno stock...then I'll dyno the headers. But that's like $75 for the dyno...so I may or may not be able to do it. Fair enough?

BTW Garrett, you know I love you bro, and I don't intend to diss the JBA's...it kinda came out like that and I apologize.
