[QUOTE="2strok4fun, post: 762162, member: 29753"] Hotter gas in a 4s pipe has greater velocity, like allready stated, but in a 2s pipe, it is not so much the gas velocity (I dont know how much it will play, but Id say not much) but the pulse wave speed. Since speed of sound is affected by temp, a hotter pipe will reflect the the - wave and the + wave back sooner, effectively shortening the pipe, making it more of a rev pipe. The amount of rpm the torque moves higher in the rpm, I would guess would not be that great, but could possibly cause a small but noticable loss of low rpm torque. All in all I would guess that the diff will be small and could maybe be overcome with a torqe ring if available, if the difference is even noticable. Go for the cosmetics. [/QUOTE]
