Awesome sound and the ease of install is amazing
Great exhaust! Shipping was very fast and the exhaust arrived in perfect condition. Has a deep awesome sound with burbles. Was able to get this installed with the help of my son in under 2 hours. Happy with my purchase and my car is now even more fun to drive!
Item was delivered unexpectedly fast! Package is clean. Installation using small ramps and a jack is easy. Sounds perfect for me. Cold start wont make your neighbors bothered. Very nice low down deep sound and very nice sound on high revs! Gorgeous and perfect!
Hands down to the HKS community and manufacture the sound of this exhaust is beautiful it looks amazing the burned tips and the HKS logo at the end of the exhaust is perfect. I'm having lots of fun driving my 10 Gen Civic Si back and from work it's a real neck twister on the road. See it for yourself in this video.
Put this on my 18 si coupe and it sounds amazing, louder and deeper growl than stock. Already had a CAI and tune but this balanced it all out at higher rpms and runs great! Deeper richer tones without being obnoxious to neighbors while still giving a big boost over stock
