Subaru impreza sti gruppe s stainless manifold on eBay (end time 04-Oct-09 20:04:23 BST)

Are the above headers any good on a 2.0L running 350-400bhp? Or are they 'overkill'? Will I lose spool with these (i'd be teaming them with a performance slip-jointed up-pipe of not too large diameter, to accelerate exhaust gases though).

Will they help the engine breathe, so as to aid in obtaining the 350-400 more 'effortlessly' than with the OEM headers (with all appropriate supp. mods/turbo, naturally)?

Any info/feedback greatfully received, thanks.

running that sort of power your deffinatly going to see the benefits of tubular headers jozzy. youl probably loose a tad of spool but gain a shed load of torques...

would you have them ceramic coated?

Cheers wrighty.

Well, as you can see, they're heat-wrapped at the mo. And it all looks tight and well applied - so I prob. wont get them coated (as the process will cost more than the headers, etc. - you have to draw the line somewhere, lol).

As I said, the performance up-pipe should offset any lost spool so, hopefully, the spool times will remain status quo, or as near as makes no difference(?)...


Anyone else have feedback on these?

harvey does performance up-pipes for g-spec style headers, cant see why he wouldnt do one for 2 bolt, apparently bob rawle likes harveys up-pipes and theyre well worth a shout...if only i hadnt had mine coated beforehand! nevermind.

They are pretty good, but can be prone to split more than the 3 Bolt ones. In saying that, they are a smaller bore size and probably more suited to your needs.

The guy selling the headers should also have the up-pipe, so worth giving him a shout.

I already have an up-pipe that should be up to the job (see thread starter )... And if I can snare these headers for around £200, I'll be happy, etc.

Thanks for the advice guys.
