NEW INFO GUYS
My friend's friend just got a ECS system on his newer gen Si. He dyno'd it and he said he got 27 more lbs of torque when it was open. He is running a test pipe.
He said it sounds good in VTEC, I think it sounds deadly, and its very illegal
What do you guys think? He said when you floor it from a stop, it doesn't do much, but once VTEC kicks in, its a beast.
