I recently bought a 94 NSX. I had it service and found out the the stock exhaust had a little kink on it; so I asked the shop to order a new Comptech exhaust. They put the car on the dyno to get the base, and after the exhaust... I gained 10 hp at the wheel, and same gain for the torque. I was very surprised that it gained that much from just an exhaust. Thought I share with all the members here.
