Gale Banks Engineering

HEAVY-DUTY PICKUP/SUBURBAN: Banks PowerPack adds a pair of stainless-steel TorqueTubes to the Stinger platform to unlock massive torque and impressive high-end power. Your PowerPack-equipped pickup or Suburban attains best gains of +70 hp and +85 lb-ft torque, with 10% better fuel economy—and never needs high octane.

PowerPack system
Includes: Lifetime Banks Ram-Air filter and service kit; Stainless, heat-shielded TorqueTube exhaust manifolds; Stainless head-pipe assemblies; Stainless, low-restriction Dynaflow dual-inlet muffler; Stainless, constant-diameter Monster exhaust with 3.5" tailpipe; 4" polished-stainless slash-cut tailpipe tip; Comprehensive Owner's Installation Manual.

Banks Ram-Air filter
Banks Ram-Air filter is a lifetime, high-flow air-cleaner element that decreases intake restriction and sends more cool, dense ram-air into your engine. Even wet or dirty, Banks Ram-Air filters outperform conventional ones, because the multi-layer design traps moisture, dust and debris on the oiled, outer surface, allowing air to move through with ease. Includes a service kit for use every 30-50,000 miles.

TorqueTube exhaust manifolds
Banks' 100% stainless TorqueTube exhaust manifolds are virtually indestructible. TorqueTubes mount without the need for sealant or gaskets that inevitably blow out because they are constructed with.625"-thick flanges that are welded on both sides, then machined flat. Includes integral heat shielding.

Dynaflow muffler
Banks replaces the factory's restrictive muffler with a stainless, free-flowing Dynaflow dual-inlet muffler that contributes greatly to eliminating exhaust backpressure. Instead of using packing that can blow out the tailpipe, Banks Dynaflow is resonance-tuned to dispel exhaust gases through a suite of chambers and 3.5" outlet. Dynaflow produces an exhaust sound that's authoritative, yet civilized.

Monster exhaust
Banks Monster exhaust outflows stock and the competition. The streamlined exhaust pipe and 3.5" tailpipe are formed of stainless, heavy-wall tubing with constant-diameter bends to slash backpressure. The polished-stainless 4" tailpipe tip provides a handsome finishing touch.
