Searching for someone in the Phoenix AZ area who would be either interested in long tube headers or be willing to lend their car to Ardent Performance for about a week. They've made a set for the 5 litre XFR and XKR https://ardent-performance.com/colle...exhaust-header but I'm after a set for the 4.2. If there's a member here willing and interested, send me a message. Many thanks.

 

not unless they’re $600 ebay specials lol

 

I remember speaking to Stuart a while back about this, he had headers for the f type 5l s/c and said the gains just didn't warrant the price .

Im just unsure how much more can be gained with the s/c 4.2 I know the n/a 4.2 would definitely get a good power jump .

by memory I think supersprint have a set for the 4.2 it's under the range rover banner on their site.

also by having this engine out I got to see first hand how tight it really is if u do intend to have a set made up I would heavily suggest the header being 2 piece to make installation just a little bit easier

 

That one guy in here........... uh, Oh.... FrikinJag, made some. Nobody purchased them.
I think he may still have a website, "FrikinFast" or such.

 

Derek passed away a couple of years ago.

 

Stuart only made short tube headers, which would never make much if any difference. He did that to retain the catalytic convertors. I'm after long tube headers which WILL make more power but it means losing the cats as the collectors will be further downstream. For my application, that's fine.

Swallows Racing offer short tubes for the 4.2, but only RHD and so far they've been reluctant to attempt an LHD.

 

I never knew.

I'd have 'Like"ed your post, but that's not what I'd mean.

 

What? I was thinking he was ignoring me wow !.
Anyone know what happened?

 

Im 5hrs away if anything..

 

Cancer, sadly, and he was so young..
