what a beautiful product! just installed it today and it sounds great. its def loud enough but not too loud. it took my friend and me a little over an hour to install. i recommend this to anyone that wants to replace their existing exhaust with one that will get you noticed.

Awesome exhaust system.... just put it on 4 days ago and love it... it really brings out that boxer rumble... and is relatively quiet at highway speeds... can't be beat for the price!

Excellent product, I would recomend this exhaust if you are looking for aggressive look and sound, I would recommend a down pipe for an enhanced sound from the EJ20, Install time was fast and easy, took about 45 minutes. HKS makes great products.

awesome exhaust. sounds and looks cool. the bending of the pipe is minimal for maximum exhaust flow. only thing you need with this is a set of new exhaust hangers.

A great exhaust at a great value! Installation was a breeze, with only slight fitment issues between the catalytic converter and midpipe. Produces a great deep throaty sound that is loud enough to get you noticed, but not loud enought to wake up your neighbors in the morning. Unfortunately, i believe that my stock exhaust hangers are in poor condition so i do experience a slight rattle at low RPM's. I reccomend this exhaust to anyone who wants to hear that famous subaru boxer engine at an affordable price.
