03+ crown victoria exhaust system options Stainless Works header vs Kooks header

[@ProudQLD]

I currently work as a Design Engineer at Kooks. I've got the headers on my 2006 P71. It wasn't difficult to install. Took me around 2.5-3 hours. Custom work included headers catted X pipe and 90 degree bend with dual tips.

[@p71c1]

well then explain me why on one side exit straight and the other side exit at an angle. Why does every tube on the passenger side make removing the starter a total PITA

[@ProudQLD]

@@p71c1 It's due to all the engine components and wiring and other parts that come in the way. The headers were designed back in 2003. I started working in 2019. But from what I've seen the way we do stuff now is way different. Back then we would build the headers around the car. Now we scan the engine bay and design the headers in CAD and then fabricate them.

I would like to get headers, but they’re just too expensive for these cars. It’s insane.

[@coyotefilms2888]

nice , I am going out to look at a 2005 crown vic 99% sure I'm gonna get it what's the reccomended exhaust system

[@BlackVicP71]

Nice work Pier, it's nice to see them side by side like that. Is the Kooks set made to work with a factory cat-back or is custom work necessary?

[@AeroSS87]

Could you explain a little more on what you did to make the SW headers work with the 5.4? I'm looking to swap my 05 relatively soon but I've not been able to find any good explanation of how to make a long tube work in conjunction. Thanks

[@qwer153624]

hope to see them running on my vik!

I want to buy capes and I want your advice only, which is the best kooks & SW

[@p71c1]

stainlwss works are the best and easier to install

[@aspieotaku3580]

I wanna get new headers but will do cat back first, headers run around 1600 bucks.

[@p71c1]

they still worth it tho :)

[@pgerber07]

Great video as always Pier

[@mrelectron6220]

Late to the party here but the SW look much better and seem like they be easier to install than the Kooks with the funky bends looks like spaghetti.

[@p71c1]

exactly and we havent talked about starter replacement with the kooks !

[@cashthekid8049]

On my 97 Vic,it was hitting the frame. That's why I asked......

[@p71c1]

+mae spraglin thats because kooks arent made for the 03- cars , only stainless works make a set for the 1992 to 2002

[@cakefaice]

+mae spraglin for 92-97 you're going to have to go with a different brand of headers. They won't fit on those years, but rather 2003+ since you have a tad more wiggle room due to the last major engine update.

Where would one get a set of manifolds for an 09 Vic that are half decently priced??

[@YorkTown1781]

will the computer give check engine codes with the headers? if yes will the tuning modules clear out all codes and give good performance?? thx.

[@GreatValueJohnnySins]

YorkTown1781 I would like to know as well.

[@p71c1]

codes will come from the fact that the o2 sensors are moved down and will take longer to heat . if you have a reader it will go away but will always come back unless you get a tune for it

[@YorkTown1781]

I'm familiar with using hondata on civics. you can shut of the rear O2 and the car will never throw a code. nice to know the crown vic has something similar. thanks for the feedback

[@78Poeboy]

im going to be dropping a lightning 5.4 into my grand marq and i wanted to know what would i have to do about headers?

[@88888javiertube]

Dakota Poe dont listend to the idiot on the video, go with kooks headers, best out there for this car,check my 05 crown victoria video doing donuts, it has kooks headers x pipe and flowmaster 40s with 4.10 gears

[@eriv4735]

el pasi The “idiot” in the video has a 5.4..modifications are needed for that motor with any header

[@juanray2614]

@@88888javiertube do you have to have a catted x pipe to go with the kook headers? I read that somewhere it says must be used with “catted stainless steel x pipe” must be used with kooks headers. Can you install kooks headers with a non catted x pipe?

[@OMAIROOOO]

I am very impressed with this but can I also do this in Lincoln Town Car 2006 !!?

Not sure if they still makes them. Obx or other knock off should still be available.

yes

[@mikedouglas6866]

Cool.. That good to know... Thanks

[@mikearbour3540]

how long did it take to change headers ? is there any tips on how to take off old ones . someone told me to cut off bolt studs , then take off manifold ,then get vise grips to remove rest of studs . if its too hard to do , how much will it cost for mech to do it.

[@p71c1]

usualy headers job requires quite a lot of time and tools to get it done properly. Need a welder,blow torch usualy to get around broken studs.

not to mentioned that your arguments on the video are stupid. u had to modify the stainless when u can get kooks and bolt them right on. nonsence.

el pasi @ 1;18 is there is something you dont get ? They were modified because I have a 5.4 engine in my crown vic and not a 4.6, that is why they were modified, does it makes more sense now ? who looks stupid now ?
