as im upping the grunt on my wrx i have been thinking about getting my headers ported but unsure where to get them done and how much they will cost,they will be fitted to a sti de-cat up-pipe that has been wrapped,is it worth while getting this ported or is it ok as it is? also is the up-pipe a slip-jointed one?

 

Drop a PM or email to Alyn at AS Performance. He took over with the ported headers and Harvey's trick up-pipes which make a LOT of difference to the spool.

 

ok matey-cheers

also how much wrap will i need for the headers and for the downpipe?

 

Couldn't say, Harvey did mine, but Alyn will know, no doubt.
