i was able to get a set of headers made by janspeed in the uk through www.4x4ag.com adrian and john were super helpfull and i look forward to dealing with them in the future. i will be doing some before and after dyno testing and will try to do a good write up with some pics.

 

I've got the JanSpeed Headers, from 4x4ag.com, as well. Excellent fit! Only issue I had, on my D1, was with the drivers side knock sensor. The header was so close, It could not be plugged in. So, I replaced it with a D2 style knock sensor. The D2 sensor has a 90 degree plug angle on it, so it does not stick out as far...
Here's a pic of the headers:

 

I contacted 4x4ag.com and was told Janspeed was working on headers for the 4.0 LR engine and that they should be available in the coming weeks...

 

yep, borla makes a header back kit for about 550. google it

 

any improvement guys with upgraded hearders??? Waking up and old thread here LOL

 

Headers alway make a nice improvement in low end power and a little MPG, add them to a decent exhaust system and a new set of O2's and you will be very pleased.

Can anyone post a link to the Borla headers? I've looked on there site and all I see is the exhaust system.

Thanks.

go to www.aluminumv8.com they show the above listing for rover headers, I don't know anyone who has them but they are recommended from another rover forum.

 

Header back means the header is not included....it is everything after the header...
