Exhaust sounds really nice from low to high revs and does not sound raspy. Can hear the car screaming from 4.5k pm and above.

What I like
Nice exhaust sound at low revs from 1.5k - 2.5k rpm.
Exhaust does not protrude out and will not hit the kerb even after lowering the car to 2 finger height.

What I do not like
The price is high
Very quiet at idling

Subaru Impreza

Review
The welds are top notch. The stainless piping is very thin, contributing to its lightweight. They even included some heat shield wrap for a brake line running close to the exhaust. It has a nice deep throated tone. On the highway, it is barely noticable at constant throttle. Stepping into the gas in 5th produces a good bit of low resonnance. Running it wide open it sounds awesome while not on the verge of making you deaf. I would really highly recommend the RM-01A to everyone in the market for a high quality exhaust that is very streetable, while sounding good. Thumbs up!

What I like
High quality exhaust that is very streetable

What I do not like
The selling price.

I bought these mufflers to add on to the exhaust system for my Nissan Latio. After some time driving with these on, I can notice that there is a good boost in my horsepower. Great low acoustics too that I must say, will be a head turner. Fear not though, these HKS Carbon Ti are legal enough for Singapore roads! I AM SATISFIED! These Carbon Ti mufflers are exactly what you need to differentiate yourself from the other "tuned" cars out there. I would recommend this muffler to anyone looking to upgrade their exhaust system. 5 stars. 10 out of 10. Whatever. JUST GET THEM!

What I like
Great sounding mufflers that provides a little extra to your car's torque.

What I do not like
The heavy unit, and also the heavy pricetag.

Review
It's almost the same as my stock exhaust, but the sound is more deep and like a growl. Sound damn nice and my buddies all now keep talking about the sweet growl my car has now. Also it's lighter than the stock exhaust, so my car also got save some weight.
