Product Details

The FlowTech Exhaust 12540FLT Long Tube Header delivers enhanced engine performance and improved fuel economy in a durable black painted finish. Engineered for optimal exhaust flow, this header features a mandrel-formed power plenum design that maximizes exhaust velocity and scavenging efficiency.

Key Features:

  • Constructed from .049 cold roll flash mild steel tubing for durability and heat resistance
  • Mandrel-bent power plenum design maintains consistent pipe diameter for maximum flow
  • Leak-proof O-ringed port seals ensure proper gasket sealing and eliminate exhaust leaks
  • Factory leak tested for maximum performance and reliability
  • Black painted finish provides corrosion resistance and a clean appearance
  • Includes all necessary mounting hardware for installation
  • Precision engineered for proper fit and performance

FlowTech long tube headers are designed to extract more horsepower and torque from your engine while improving fuel efficiency by reducing exhaust backpressure. The longer primary tubes provide better exhaust scavenging compared to shorty headers, making them ideal for performance applications.

Its fine. No complaints.

Quick delivery and the product was as advertised.

Fast shipping good price.

Great prices and super fast delivery!

I ordered a new latch for my center console and it fit perfectly. I could have bought it locally but the local store didn't have it in stock. I figured if it had to be ordered I could order it sent to my house.

Easy to use even though it did seem to crash last night

Satisfied with prices. Have not installed items yet.

Super quick shipping, cheapest price for brand name product, and $5 for writing review! So far I really like this company!

Ordered Tein lowering springs. Shipment arrived fairly quick. Overall process was great. Would order from them again.

good price, prompt delivery. no complaints.

great service. Been looking for this trounce product for over a year. best hand cleaner i have ever used. makes the orange stuf seem like using just water.

By far the best price, easy ordering, and fast service, what else is there?

Great prices, great service, fast shipping!

I placed an order for Race Ramps and not only were they the best price I could find, but the shipping time was excellent as well!

Very fast shipping! I got an email saying it was shipping 2 days after I placed my order, when I checked the tracking it was already delivered to my house! Will shop again.

Placed order on Wednesday and item was shipped on Friday, could not of asked for faster service. <br>
