If custom pipes are going to cost $1000, and you definitely want pipes, buy the ones off the shelf, just remember they will kill bottom end for top end power.
Yes, that pacesetter exhaust it's not what I'm looking for. I forget definitively about those exhausts...

I've been talking with some people and I've found someone that can make me the exhaust. they want around 800 EUR if THEY do the calculations, I have to ask them to make the pipes with the specs you told me.

If I change the intake camshaft you have to remade the calculations, correct?

I've been looking for this camshafts but I'm not sure if they will raise the peak power or just improve the power on mid-high range :/

Or better stay with stock intake cams?

Also I found I have two car mufflers in the exhaust line. If I remove those middle mufflers I can improve the gas flow and gain more horsepower (i know it won't be to much)?
