FAQ

Q1: What are the Flashark Long Tube Headers made of?

The Flashark Long Tube Headers are constructed from high-quality T304 stainless steel. This material ensures durability, resistance to corrosion, and long-lasting performance, making them an ideal choice for high-performance exhaust systems in Chevy/GMC vehicles.

Q2: Will these headers fit my standard Chevy 350 Small Block engine?

Yes, these headers are specifically engineered for the Chevy 350 (5.7L) and 305 (5.0L) Small Block Chevy (SBC) platform. They are a direct performance upgrade for 1988-1997 Chevy and GMC trucks and SUVs, ensuring a precision fit for your 350 build.

Q3: What performance gains can I expect on a Chevy 350?

By replacing restrictive factory manifolds with these high-flow Chevy 350 headers, you can expect an immediate gain of 10-15 horsepower and significantly improved torque. The long tube design optimizes exhaust scavenging, allowing your SBC engine to breathe much more efficiently.

Q4: Are these headers compatible with the 1996-1997 5.7 Vortec engine?

Absolutely. While many aftermarket options struggle with fitment, these are designed to be the ideal 5.7 Vortec headers for the late-model C/K series. They accommodate the Vortec head configuration perfectly while maintaining proper clearance within the 88-97 chassis.

Q5: How do these headers improve performance on a 5.7 Vortec vs. TBI?

Whether you have the older TBI setup or the high-output 5.7 Vortec, our long tube design reduces backpressure that standard manifolds create. For 5.7L Vortec owners, this means better exhaust flow and a more aggressive V8 sound that stock systems simply can't match.

Q6: Do these headers come with all necessary installation parts?

Yes, the Flashark Long Tube Headers come with everything you need for installation, including reducers, bolts, and a metal gasket. They also feature TIG-welded construction and a CNC-machined flange for precise fitment.

Installing Flashark Long Tube Headers will enhance the exhaust sound of your vehicle, providing a deeper, more aggressive tone. The improved exhaust flow can result in a more pronounced and dynamic engine note, particularly at higher RPMs.

Q8: Are these headers easy to install, or do I need professional help?

While installation is relatively straightforward for those with basic mechanical knowledge, we recommend professional installation to ensure optimal performance and fitment. These headers are designed to work seamlessly with your engine, but precise alignment is crucial for maximum efficiency.

Q9: What is the warranty on the Flashark Long Tube Headers?

The Flashark Long Tube Headers are backed by a manufacturer warranty for quality and performance. The headers are made from high-grade stainless steel, and the craftsmanship is guaranteed to withstand the test of time.
