Features:HKS Turbo Exhaust Manifold for the Subaru WRX and STi is an OEM replacement (using the standard 2 bolt uppipe connection) which comes with gaskets and a heat shield blanket. The HKS headers are lighter and flow more efficiently than the factory manifold which will increase your horsepower and torque while giving you a more aggressive sound.
Awesome quality and Perfect fit. Install was a breeze and I appreciate that it comes with a heat shield.
I bought this header because of the unequal length type, construction and the HKS brand name. And I was not disappointed. Car is 2012 Forester XT.
Installation was completed well within one hour (cold engine) with ease. Everything fits really well. The complete kit from HKS with all necessary gaskets made it more convenient.
The car now pulls much harder in the higher rpms. No loss of torque at low rpms, but throttle response around 2500rpms is now just a bit softer. I don't mind this trade off at all.
I installed it without wrapping, because for daily use this is better for longevity. And I am sure HKS has thought about using the header without any wrap that they also provided a metal heat shield for the post collector pipe segment and a heat shield sticker for the oil pan.
Lastly, Import Image Racing service is top notch! Ordering was easy, and the shipment arrived on my hand Just 2 weeks later (including being held at Customs on my end for about 5 days). This is not my first buy from IIR and certainly not the last.
10/10 header for its price, have them paired up with invidia Catless downpipe/ Crawford gk2 exhaust straight screams.
My headers see a lot of abuse. A lot of heat. A lot of anti-lag. A lot of shaking from rotational idle. My tomei failed. These HKS are holding strong over a year later.
Headers work great with killer bee oil pan on my 2007 STI Limited
Great looking ! Lightweight adds a nice sound ‘ bolts right up
Awsom
Definitely have to say build quality is very good, I understand that some headers are twice or three times the price, but these are great, solid and were recommended by my tuner so can't go wrong there. Install was a breeze, I'm not counting the fight to get the nuts off my up-pipe, took probably 45 minutes total. If you are on the fence I say go for it! Paired with the Tomei exhaust it's a completely a killer smooth setup!
Very good quality for the price not breaking the bank
Quality is unmatched for the price. Read forums and everything and this header seemed to be the go-to if you are on a budget but want the ELH performance! Welds look solid, would buy from HKS again and IIR!
