Customer Reviews
These are not loud, they get a bit raspy above 4500 RPM. They look amazing on my silver 2020 WRX Premium. I am not running an aftermarket J pipe yet to give you more perspective. Super easy to install. They bolt right up. Also used the Grimmspeed adapter and added the dry con filter at the same time. One thing to note about the HKS set up is their use of stainless steel on the mid and Y pipe to reduce weight, they are light! The entire set up is super high quality. Shipping was quick from MA on the Catback, the adaptor & air filter shipped from a different warehouse and took a few more days but that’s the way she goes. Not gonna get all “Karen” about that, supply chain, logistics and overall operations are never easy lol! ✌️
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!
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.
