I have a 2000 all stock rt/10, yesterday it dyno at 435.8 Im interested to see what other STOCK, PUMP GAS, Vipers have done. No smooth tubes or filters, totally stock. Its also funny my friends viper with headers, cats, exhast only did 442 rwhp. Do you guys think I should spend 7000 for 7 more hp. (I just had to rub it in you know who your are.)
