Loud pipes for a viper?

[Sxviperrules99]

i am pretty sre they didnt not make pipes for sx vipers. Only hauck/cpr (simmons), aaen, bender, slp, speedwerx, jaws and thats about it

Thats strange. The guy swears they are PSI's. I wonder what the deal is? He had them on his viper so.... As long as the sleds jetted correctly and the pipes fit, would they work on the viper?

Black viper (the orca) has Simons cpr's and the blue viper has aaen pipes. Video taken with same phone for an even audio reference. Anything is louder than stock.
