Here is some info on the Hytech exhaust.
HyTech's full exhaust system for the Type R produces 20 HP and 22 lbs of torque, with the aid of tuning devices like cam gears and an Apexi VAFC. This Type R design comes form the CART Toyota Atlantic series, where HyTech is on virtually all of the competitors cars. The system is full stainless steel and comes with 2 1/2 cat and our own double bypass stainless muffler for the quietest ride and the least restrictive on the market.
