I think mine is a japspeed one but hasnt got any markings on it, bought it second hand cheap, only got it because had a solid uppipe and slip joints. Personly if i was spending 300 on a mani id get one with a 3 bolt uppipe flange, my 2 bolt one kept blowing gaskets so i just welded them together, was a bit of a bugger to fit but if u enlarge the head stud holes to 14mm fits a treat, i also welded a web between the runners before the slip joint on the other side to the collector, had it on since july and no issues yet (except uppipe flange)


Half way through wrapping

Can see the slip joint and uppipe in this one

Had one fitted on mine, slight pain to fit but had no problems with it. Couldn't get plastic sheild back on as was to close to manifold, massive pain in the ***.

The up pipe in your picture, does that normally replace a precat in the system?

For what reason do you want to change? I,ve seen dyno tests on some that provide less power than stock item. So do your research to make sure it,ll be better than stock

Mine didnt have a precat, my standard up pipe had a flexi and it was leaking, so i just changed the lot while i had it off the road

Cheers for the help guys i have an 07 sti and am goin to have it remapped in jan so wanted to do all the bits i want first

I don't really want to go inside the engine at this stage so was looking at full decat, induction, front mount and manifold. will be getting the walbro pump aswell. not sure what else to do really without spending big money on turbos etc. any suggestions on bits to do would be great
