We are in the process of testing these exhaust and gathering video and sound clips for each. As far as the looks and quality, they are very impressive. The welds are amazing, almost looks like a machine/computer controlled weld, they are that perfect. The exhaust cans are small and fit into the vehicle very well. The sound generated from these small cans is similar to Taitec's JGTC Parallel exhaust, but more robust in VTEC.
Route KS manufacturers for the race track first, then for the street enthusist. Their technology is carried over from extensive track testing to their street performance vehicles. They also concerned with the emission levels and have addressed them with the One Spec & Two Spec LEV models.
