I brought stainless headers from Japspeed, they blew from new, i had the flanges skimmed as they were like bananas.
Headers were there so called spec 2 best ones,£245 plus £40 for the skimming and still they blew.
I called Japspeed they said sorry but as you have fitted them we will not change them.
There attitude stank.

I would never go any where near them again

I actually got a set off of ebay which seem really good.
Word of advice, If you do go for headers do not go for the 2 bolt type with seperate up pipe, they are ****e.

Check out piston heads or ebay there are plenty of stainless downpipes, Remember as they are stainless it dos'nt matter if they are 2nd hand as still look like new.
