going by what ive heard about the headers from ebay its a case of avoid like the plague, especially the megan ones

 

They have a nasty habit of splitting around the welds...

By cheap, buy twice is the motto in this case. Avoid.

Do a search for Harvey headers- he's a top chap and will sell you kit that with do the job- not split.

 

will look him up now! 'Harvey headers'
thanks for the help peeps much apprieciated!

They are a strange, manky looking, set up. 25 hp?

There was a problem with early tubular headers that had a 2 bolt fixing to the up pipe. They cracked regularly.

The later version with a 3 bolt up fixing to the up-pipe are MUCH better and also give good power gains. Certainly not 25 hp even when mapped but good gains nonetheless. Not yet changed a set of 3 bolters. Nearly skinted me replacing 2 bolt versions

You don't really need tubular headers until you are in the 380 hp range. Of course you can fit them at any time, BUT, ported standards will work well up to the 380 mark.

We do ported headers as well as Harvey.
