Easy install, perfect compliment to the subie rumble

Even though the directions are only in Japanese, this exhaust was extremely easy to install. It took me approximately 30 minutes including removing stubborn rusty stock bolts and offers an amazing enhancement to the subie rumble. By itself, it is not the loudest exhaust but it has made my WRX sound mean as hell. Will be the perfect companion to an aftermarket downpipe. As with any HKS product, it is well worth the price especially because it is titanium. I'm happy to no longer worry about the Minnesota winters eating my exhaust. 10/10 would recommend!

HKS Hi-power spec L-II

Great sound with a different look. Barely noticeable in the cabin at road speeds. No drone whatsoever. Sounds very nice at wide open throttle. I didn't want quad tips or single outlet, this was perfect for what I was looking for.
