I was looking at GReddy's website and they make exhausts for the 1992-1996 Prelude but it says as a side note that it fits only the VTEC model. Is the exhaust different between the Si and Si-VTEC engines? I am going to remain street legal with my build and I nixed the SMSP custom design for that reason but will the GReddy SP2 or EVO2 fit my Si?
