Amazing build quality

My tuner recommended this header. Build quality is top tier. Comes with standoffs for skid plate. Adds uniqueness to exhaust tone. Mating surfaces were impeccable. There's nothing to dislike

Amazing and worthwhile modification for the 15+ WRX

I chose the non-Swain coated headers after doing some research and talking to my performance coating guys and saved a bit of money on having them ceramic coat them instead (also wanted a different color than the whitish hue of the Swain-coated ones). But, as people are saying, you will need to buy new gaskets, which Dane did hook me up with. So shout out to him and all the guys and gals at IIR for always knocking it out of the park! Install was a little challenging by myself in the parking lot of my apartment complex, but it can be done. Just definitely need some PB blaster action on the header and J-pipe nuts and bolts, some time and patience. Luckily, the shop who had my car last didn't reinstall 4 of the 6 header-to-engine nuts, so the removal of the stock turbo/header assembly was easier than it could have been. So, yay me! All in all, I only had one nut seized onto a stud (header-to-turbo), which I definitely reused as I could easily extract the stud/nut combo.

They sound great.

I installed them with ease. The only thing I didn't like was I had to remove my aftermarket drain plug I had, it would allow me not to have to remove the plug for oil changes. But you give and take here and there when modifying.

You need headers

Top notch customer service and fast shipping. These guys are great. The headers are beautifully crafted. I did some research and my tuner said Killer B is the way to go. I don’t have them on yet as my tuner is booked out a couple months but I’m sure I’ll love these headers.

You get what you pay for

Damn!! Those are some pretty welds. This is far superior to the OEM. Nice thick flanges, perfect welds smooth bends. Everything you could ask for from Killer B
