home made header pipe

would a home made header pipe make a difference in performance? Say a 1 3/4" or 2" I know a guy who bends exhaust, and im sure he can make me one.

Even if u knew what u were doing, it wouldnt be as good as stock.

I just happen to have an old style FMF MegaMaxII headpipe I'd be willing to sell for $20 bucks.

It might could be bent to fit a stock silencer...
