My car was at stage 2 with an Invidia catted downpipe and Q300 exhaust when I installed this. According to my butt dyno, this felt like it improved the overall power of the car...especially over 3,500 rpms. Not as much of a gain as going to stage 1 or stage 2, but noticeable. I love the extra power, but I'm much happier about the header reducing the drone while driving on the freeway....it was pretty bad with the stock exhaust manifold and turbo back exhaust. The engine also runs a LOT smoother through the entire rpm range. I would buy it again. Installation was straightforward. Recommend getting an O2 sensor socket if you don't already have one.

The very same part for the WRX model is over $400 more on this same website. Don't buy it it's the exact same part as this but this one for the STI is a ton cheaper, fits like butter sounds amazing and huge gains across the board. Don't waste $400 and get the other set for the WRX. This will fit your WRX even though it says STI only

Put these on my 2005 sti. Personally i like the equal length sound, but at times miss the rumble! Packaging was good and shipping was fast. Coming on a year having these on and no cracks/rust or anything. Gained some power out of these too! Only thing i didnt like was the heatshield attaching to the headers with worm clamps.. kind of janky if you tell me.

I was happy with my purchase of this header and the shipping of the product arrived sooner than expected. The packaging was spot on and the product itself was impeccable and came with all the necessary hardware. The install took about an hour and a half which the most time consuming part was taking off the heat shield of the factory header to remove the oem part. Once the oem header is off the HKS header fit perfectly with no issues what so ever. I am glad they included a sheet of heat wrap for the oil pan area to help eliminate heat build up around the oil pan and also happy that the factory under carriage cover was able to go back on.

I understand that to get the full benefits out of these headers that you need a tune. But to just imstall them and run them do i absolutely need to get my car tuned right away?
A: No, a tune is not required after install. As you mentioned, you wont see the full benefit of the header until you do have the tune done.
