HKS Hi-Power Cat-Back Turbo Exhaust
65mm O.D. - 2.5 Inch
Tip is 115mm
Inspired and designed from endurance and GT racing in Japan, HKS developed its Hi-Power Exhaust system for both turbocharged and naturally aspirated applications. HKS has incorporated this new race inspired offset muffler and piping design into many street applications, which offers a greater flow and higher-PRM power gains due to the less restrictive design. This is achieved by eliminating unnecessary bends for the straightest exhaust path.
For turbocharged applications, the large in a Silent Hiand smooth exhaust flow allows greater exhaust velocity for better mid-range boost response and high-RPM power. Naturally aspirated vehicles also benefit from greater exhaust flow capacity as engine tuning levels increase. Certain applications are available -Power version which has an inner silencer built into the muffler. Like Drager Exhaust systems, Hi-Power Exhaust systems are made from SUS304 stainless steel muffler and tip assemblies. No Silencer Included

I decided on this one over the slightly smaller model for my 03 type s and I am thoroughly impressed. The quality of the product is great and the sound is exactly what I wanted. It has a nice deep tone and is loud enough when you get higher up in the rpms. I did notice a little bit of surface rust on some of the welds after having it installed for a few months but given that I live near the ocean and have driven on salted roaks from snow that is expected and I can easily fix with a little sandpaper and paint. Overall a hell of an exhaust.

Deep Throat Sound
Product was even better than I expected. Watched a bunch of youtube videos trying to find which exhaust system would have the best note. After purchasing it and getting it installed, the look of the finished product is better than the photos show. Doesn't sound like a cheap ricer exhaust. Super throaty as if the car didn't only have a 4 cylinder under the hood. Great product

I had an injen catback for a few years which I really liked but started rattling inside the muffler. Decided on this and it turned out to sound a little better and is also a little bigger which doesn't hurt. Fitment was good besides the bumper touching issue. I trimmed it up a little and it's not much of a problem now. Also like the slight angle of it as well. Matched with a skunk2 alpha header and really enjoy the sound and performance gain of the combo

Sexy deep tone that really opens up when you vtec and growls at lower rpms but can also be quiet when you need to be. Really fast shipping and excellent customer service from kseriesparts

The item took a little long to ship being it out of stock for over a month! But that's not to say the product is bad, it's actually the complete opposite. HKS packaging is outstanding, quality and craftsmanship is unbelievable, muffler fitment was a little tight but it was fine. For people that has burnt bumper, you can buy aluminum heat tape or heat shield from home depot or ebay to protect the bumper from burning up. OVER ALL a definite plus!

Bought this exhaust and it sounds absolutely great! Loud but not to loud. I was between this and the greddy and im definitely glad i got this. Awesome deep tone and fits my 02 rsx-s perfect. Not to mention crsx has extremely fast shipping.

I chose this exhaust cause It's not quite 3 inches which means it wont be obnoxiously loud, but it's also a bit larger than 2.5 like 2.78 so it will flow well. It sounds great. It has this amazing sound when you high throttle shift and a Nice Deep Growl in lower RPM's. Some others sounded deep, but they didn't growl. It definitely frees up some strong horses. Plus aesthetically the angled tip is Le Sex :D

At first i was going to go with a cheaper exhaust like the dc or the apex n1. then all of a sudden i get a bunch of money and thought id look around a little more and came across the hks hi power. this is an excellent exhaust. it was very easy to install (the hardest part was taking off the stock exhaust). the only downside is that it does burn the rear bumper but i went to autozone and picked up longer exhaust hangers so it sits a little lower and even looks a little nicer. aside from the burnt bumper, i still give this exhaust 5 stars. it sounds great, gives off a nice tone at start, and around 2-3k rpms the sound is so deep it makes me ears want to pop, yet its not a pig magnet. excellent excellent excellent.

very good exhaust. only complaints i have are it hangs a little low so it gets scraped on everything now. and the tip really is huge, it's already melted a small hole in my bumper.

Thought this exhaust might be too loud, and at first I thought it was. But after about a week, I wouldn't change it at all. Loud when you want it, quiet when you don't. The only negative part about it is when the car is cold and you start it, it idles high which makes the exhaust real loud.

Get this exhaust.
HKS has been around forever, all thier products are quality made. I would however suggest this exhaust over the smaller diameter version. The K20 loves to breathe and this exhaust is great to open that up. I've owned both versions of this exhaust and never noticed a drop in torque with either. This is a Great product.

Ordered this on a saturday and recieved it on the next wednesday. great shipping time. product was in great condition with great welds. install took 30 mins. only difficult part was taking out the old exhaust. my car is basically stock buti plan on running a s/c in 5 yrs. its sounds great; nice and deep and full. drowns but that doesnt bother me. only drowns during throttle changes not in constant speed. only thing i dont like is the muffler. i like how it is slanted but the tip is HUGE. 4inches. imo its kinda ugly but after awhile i got used to it. overall get it. its worth it.

I have upgraded from an Greddy Evo 2 to this HKS HI-Power. And the sound is amazing with BCRH. Install within 30 minutes and its worth it.

I installed this exhaust in less than 30 minutes. The fitment is superb as well as the quality and sound. It is a little deeper than the 60mm (NA version) and is a little louder as well.I would highly recommend this exhaust!!
