He's got it dynoed in at 710 horse and 785 ft lbs of torque. You'd think he has some sort of backpressure issue even with that power...

that guy is a moron, a single 4 inch pipe flows like 660 hp now he has way too much money in his exhaust and no ground clearance.

2 1/2 is the way to go.

A 2.75” (stock) single system is good for a 310hp engine with zero loss…
A 3” Single system is good for a 370hp engine with zero loss…
A 3.5” Single system is good for a 503hp engine with zero loss…
A 4” Single system is good for a 657hp engine with zero loss…
A 2.25” dual system is good for a 457hp engine with zero loss…
A 2.5” dual system is good for a 513hp engine with zero loss…
A 3” dual system is good for a 812hp engine with zero loss…
