The HKS Hi-Power Dual Exhaust System is a cat-back system that installs easily and performs powerfully, ensuring that your engine can draw all the air it needs for high performance.

Amazing sound and looks!

This exhaust is everything I dreamed of having on my Evo. When you get on the throtle it really opens up. I absolutely love this exhaust and would recommend it to anyone with and Evo.

Great mod for stock or next to stock Evos at a fantastic price

As this is my first real mod to my 2013 Evo MR, I like it a lot. As far as the sound goes, personally I think its perfect, loud enough to turn some heads and people know its not stock, but quiet enough to not piss off the neighbors when you come home late. Thats also a big plus as a california resident, not loud enough to get pulled over either. Its throaty and rumbles good and you get some more feedback in the cabin as well as plenty outside. As far as install goes, it was a process but Throtl's video on youtube is a great guide on how to get it done. I would recommend a buddy to help install this one. Check my Instagram (gubby_boi) for the videos, feel free to message me with any questions too!

Great exhaust

love this new exhaust

Great deep sound, easy install.

This is definitely a quieter exhaust at idle for standard setups, but for me it still a bit loud at idle on a fully built motor. I switched from the ets extreme system, which was just way too loud on the new build. The sound is great and the install was straight forward and easy. Removing the tow hook was honestly a breeze and not nearly as big of a concern as some people think. HKS includes clear instructions on how to remove the tow hook and move the charcoal canister over for clearance, no need to remove the canister. The fitment is also great (just make sure to check orientation of hangers) and I did not have the cookie monster problem that others had mentioned. Overall great exhaust, especially for the price.
