HKS 02-05 Civic Si Hi-Power Cat-Back Exhaust Reviews

Came fast & was a straight forward and easy install. Comes with a silencer & all the parts needed. 10/10 best sounding ep3 exhaust with good flow. No drone and sounds amazing with ZERO rasp and gives the K20 a good deep tone.

I have a 2004 ep3 with dc sports headers and this exhaust sounds so good with it! Shifting from 1st to 2nd and to 3rd all high revs gives a slight pop, it's amazing to hear! Highly recommend!

Definitely made the right choice. Looks amazing and has Deep tones. definitely some of the best exhaust I've heard on a 4 cylinder engine. Much smoother through power band now also.

Gave me just what I was looking for. Not too loud, but certainly not quiet. Nice deep tones. I was worried it might sound fart boxy being that it was going on a Honda and we all know how bad they can potentially sound, but that was not the case with this hks. I'm happy as a clam.

Great product easy installation. Sounds smooth and looks great . Recommend purchasing

Easy to install, other than removing the bolts on the cat. The sound is deep and there is some drone but it's not unbearable by any means. I felt more of a punch at the top end over the 2 1/4 straight pipe that I had before. I love the look of the exhaust with the can angled out at the back. I highly recommend this exhaust to anyone looking for good power and a great sound.

excellent exhaust. performance gains in the low to mid-range is decent, but in the high's is where it really shines. you can feel a good difference from stock exhaust to this when you WOT it. sound is amazing as well, although mine is VERY loud compared to my other friend with same exhaust, reason being that i have a test pipe. best exhaust imho for the ep3... or for any k-series motor for that matter!
