The pipe is 3" in diameter and the filter is the same S&B cone filter used on aftermarket LS1 Corvette intakes.

The car is actually a good deal quicker, especially past 4k rpm. I am truly suprised with how much it gained. The engine sounds pretty cool too.

I had the filter and most of the pipe, so the total bill for the project was $10.42.

I am eventually going to paint it black and hand polish what I can of the engine.
