exhaust manifold

[liverpool1]

hi i am thinking of changing the stock exhaust manifold for a XSPOWER Tubular Exhaust Manifold will this be ok for my evo7 fq300 will there be any increase in power is it worth going down this route cheers any thoughts?

stick with the standard one mate, you wont see any power gains with the xs and you also run the risk of it cracking on you (quite common)

standard manifold is good for over 400hp

xs power manifolds are crap , too much stress is placed on them in the forming process which causes the thin as it is 304 stainles to crack when they heat and cool so much , 316 stainless is the best to go for but power gains are minimal unless being ported etc to match and mapped

As above there rubbish.
the standard manifold is good for up to 500hp. i currently use the standard manifold and im running 442hp and 480lb ft torque
