I found this helpful. Maybe it will help whoever wants to buy a new Exhaust system. Not all system is shown but at least gives you an idea a bit.
<---- Yeap, its real! lol, I got a feeling that question will come one day. No, its not real. Take a VERY close look.
Can someone explain to me why the HKS hipower and HKS Carbon Ti would be different? You know, considering they are both exactly the same design except the Carbon Ti's piping is polished and the muffler is wrapped in Carbon Fiber and has a titanium tip. Explain to me how the Ti would be louder.
Carbon fiber adds the bling note, much as V-Tek stickers add the HPs, y0. No, I seriously don't know, but you have a good point.
The muffler is the same, just wrapped in carbon fiber and has a Titanium tip. The piping is the same, the CarbonTi version is polished. The inside of the pipe is stainless, just like the outside. Bends are the same, resonator is the same, muffler is the same.
I looked at the couple sites that offer both and upon quick glance it looks like there is/was a CB offered in the CarbonTi w/o a resonator. that could be it
