exhaust baffled?
upon start up i was shocked that there was not much differnce in sound
exactly why is it that the zo6 has no pre cats?is it the heads iplan on bolting on as much gm perfermance parts as possible will the 03 z06 cat assy work on my car or will it set off a check engine light also will the maf sensor from a 03 do the same or will i have to remap the ecm?will i gain anything for my efforts i also plan on installing ported ls6 heads and a ls6 hot cam.
