the mountune one is exactly the same

for 400quid its the best there is for the price

and for me its the only one that would fit in the fiesta bay

of course the likes of primary designs are better built and use far superior materials but it comes with the 1k price tag

ive had a ggr manifold aswell,looked well built but wouldnt fit my bay

why not try the milltek manifold 660quid and its stainless should give the same results in torque if not better
