Learning 91, where did you get your bands to connect at the collector and also the X pipe. BTW, the pipes look good.

Any of you try these headers on a fox with a stock power rack and steering shaft?

Im using the stock shaft but needed to weld on a smaller ebay steering u-joint. The stock rag joint would not fit between the tubes.

Ah thanks for the replies guys, would it be a simple matter of just swapping out my steering shaft directly for a flaming river unit for instance?..
Such as no extra drama or mods just disconnect from the rack and steering column at the engine bay firewall side, install the new shaft into my power rack, and I'm good to go? I appreciate the help, just need to know if it's truly that drama free.

Your level of success depends on what K-member/steering shaft combination your headers were originally prototyped to fit with. All the aftermarket K-members relocate the steering rack from the stock Fox body position, which in turn draws the steering shaft along with it.

A few examples of this would be as follows:
UPR 5.0 K-member- moves the rack mounting position up .5"
AJE K-member- moves the rack mounting position down 1-1/4" and over towards the driver side by 1/4" from the stock position. The engine is also moved closer to the vehicle centerline than stock.
Team Z swap K-member- moves the rack mounting position down 1-1/4" and over towards the passenger side by 3/4" from the stock position. The engine is also moved closer to the vehicle centerline than stock.


As you can tell, there is no standard engine, steering rack/shaft position used by all K-member suppliers, so a set of headers that works well on one user's car may have considerable interference on another user's car that is using a different K-member.

I'm using a stock rack, flaming river shaft with Team Z K member, it is very tight around the u joint on shaft.

Thanks for the detailed reply. I'm using an aje kmember along with all aje related parts like motor mounts and transmission crossmember. It looks like the speed engineering headers were made to work with an Aje kmember. I'm currently using a stock power rack and shaft with hedman midlength 1 3/4" headers. I shimmed my steering column so there is no rubbing. The flaming river shaft seems to be the ticket to success with the 1 7/8" headers based on what people are saying.

I looked for those headers on the site and did not see them how much are they?

Default Do they fit with Maximum Motorsport K?

I emailed Speed Engineering yesterday and asked if they knew if their headers would fit with a Maximum Motorsport K in a Fox. I was impressed that they got back to me within an hour or so, but sad to hear that they have not tested their headers with a MM K, so I'm wondering if anyone here has tried this? I'm running the MM 5.0 K, not the 4.6.

The specific engine mounts you use will have an affect on header compatibility with the Maximum Motorsports K-member as well as the K-member itself.
