Pypes street pro vs race pro vs other options for SBC?

Pypes F-150 Race Pro Single Exhaust System with Black Tips - Middle Side Exit SFT29RB (15-20 5.0L F-150)

I think Envy is going to be a fun little car. James has the numbers matching 455 pounding out 493 hp and 550 lb-ft of torque. That will be pushing through a Pypes 2.5” stainless exhaust system with Race Pro mufflers. A Tremec 5 speed with hydraulic clutch mated to a Quick Performance 9” rear end with 3.50 gears will handle the horsepower. Riding on a UMI Performance Stage 3.5 suspension kit. Year One 17x9 Honeycomb wheels with Nitto 255/50/17s on all four corners will make sure to put that power
