Chow,
Yep, that's exactly been my philosophy too.
That's why I went with the DynoMax exhaust system on my Saleen; e.g. it was the only one (other than Borla) that was offered in stainless steel at that time. Everyone else was either aluminized or painted mild steel.
Plus it didn't hurt that DynoMax was the OEM system chosen by Saleen for their SSC model.
However, I did add the BBK catalytic 'H' pipe which is aluminized & it has held up as well as the stainless steel components.
