i was debating on 2.5 vs 3" when building my 500+ hp 467 & did lots of reading here & other places, read lots of guys say they went faster with the bigger exhaust at these power levels. the tail pipes can be 2.5 due to exhaust gasses cooling off so much that far down the system. if its only a daily driver & you dont ever plan to race the car or uprgade the engine for more power then the 2.5 will work fine, but then again if its only a daily driver & you dont care about power loss, why build such a powerful expensive engine? a stock'ish iron head 455 would be more than enough for daily use & fun street driving.

i followed what cliff advises: garden hose for fuel line & sewer pipe for exhaust!
