I was thinking of changing my headers soon.. but I want some opinions cuz I see some ppl haves kooks headers n than I see some ppl with cobra headers .
Which ones would be better to increase hp? And or better for a daily driven mm? And wen I change the headers is there anything else I should change wen doing so??
 
My understanding of it all is like this stainless works if you want full length long tubes, kooks are more of a mid length design. The vehicle should be tuned after the installation of either. Locking header bolts from either stage 8 or ARP should be considered as well. If by cobra headers you are talking about the stock cobra manifolds that some people are running, I would personally pass on those since they are almost identical to the Marauder ones.
Hope this helps.
 
I can offer you pretty good pricing on the Stainless Works headers if you want to go the long tube route.

I would not bother with the cobra shorty headers. They are not the best option.
 
I have the complete long tube Stainless Works system on my '04 Silver Birch. I can't say that the horsepower increased much but the torque certainly did.
There is a great software program by "Performance Trends" that allows you to do a "what[/B] if" before spending money for parts you can't return. I use the program for all of my rebuilds and mods before I order parts. The software has always been within 5% of the actually dyno data.

Do you have a tune or get a re-tune adjustment after installing the header system?
 
A dyno tune can yield some more power.


Something I have yet to do since my complete S.W. System. Really curious where I'd be if I upped the pulley back to 3.2 and leave the +4 lower (way too much boost right now creating nothing but heat..) plus with the cams?

Make that I need to know. Must schedule appointment... Just been lazy.

A true long tube design will yield the best results.Another benefit is the upgrade to 304 stainless steel to rid yourself of rusty stock manifolds. We offer an 1-5/8" primary which is the perfect compliment to the OHC design for such a heavy car.

Part Number MAUCAT
Retail Price $1430
2003-04 Mercury Marauder headers, high flow metal matrix converters and 2 1/2" lead pipes. 1 5/8" primary tubes with 3" OD collectors. Long tube design makes great power and mid range torque. 3/8" SS CNC laser cut flanges are port matched to the cylinder head for optimal flow and maximum performance. Designed for use with factory exhaust system.

Check with MO's Speed Shop, good shop great guys!!
 
SW?

How well to the Stainless Works headers really fit?

Do they clear all components, without any mods, such as shimming a motor mount? Do they clear the steering shaft?

Were there any changes made to them since the original design, so that the current model fits better than a prior?

Enquiring minds want to know!

We have found that the fitment on the headers is very good.

Then again, we install car parts for a living so your results may vary. :cool:
 
NICE!

That's very nice! But, Do they clear all components, without any mods, such as shimming a motor mount? Do they clear the steering shaft?

I only ask because I understand there have been "problems" in said areas.

This^ I installed a couple sets last year and yes, they cleared everything. As for the X pipe and trying to keep centered perfectly, tail pipe fitment, and hanger design, not so much. But with enough "adjusting" with my screw jacks and my deadblow, it also seams to clear all now.

Also, I am more of a fan of OEM gaskets, and new factory studs and lock nuts.

Yeah, I'd hate to get a set with the ceramic coating only to have that damaged because they needed some "adjustments" like with a hammer.

But I'm really just concerned about it on my (tighter) '01, I went ahead and ordered them for my '08 with the coating after both Chris and Paul at Stainless works assured me there'd be no problems (haven't installed them yet though).

Ha! You wanna see some REAL massaging...? Look what I went thru on my last set of coated headers! Keep in mind I was simply taking one for the team to see if they fit because I had a little extra cash and time. You know, the two things we never get.. Meh, I still used them for a year and half or so, they served their use..
