for all that time and money you spent on materials, you could have spent 100 bucks and bout an hks 3k pipe wich flows better and is already polished and looks alot better

HKS 3000 pipe is not polished.

HKS 3000 pipe is definitely superior for flow, the stock 3000 pipe can almost fit inside the HKS pipe. I personally wouldn't waste time polishing the stock 3000 pipe, it's a major bottleneck which should be removed.

Damn, where do you guys get the patience to polish all that stuff? I got bored just polishing a 3"x3" piece.

Couldn't you just remove the restriction where the 3000 pipe bottlenecks? It's 2.5 inches in diameter going into the throttle body.

You could, but the HKS 3000 pipe would still be bigger. The stock 3000 pipe at it's largest point isn't as big as the HKS 3000. If my HKS 3000 pipe hadn't come with my HKS IC kit I would have simply made my own 3000 pipe.
