Product Details

The FlowTech Exhaust 11150FLT Long Tube Header delivers enhanced engine performance and improved fuel economy through precision-engineered exhaust flow. Featuring a mandrel-formed power plenum design, this header maximizes exhaust scavenging to extract more horsepower from your engine while maintaining excellent street manners.

Key Features:

  • Constructed of durable .049 cold roll flash mild steel tubing for long-lasting performance
  • Mandrel-bent primary tubes maintain consistent diameter for optimal exhaust flow
  • Leak-proof O-ring port seals ensure maximum performance and prevent exhaust leaks
  • Factory-style black paint finish provides corrosion resistance and a clean appearance
  • Each header is individually leak-tested before shipping to guarantee quality
  • Includes all necessary mounting hardware for straightforward installation
  • Precision-engineered design ensures proper fit and alignment with factory mounting points

FlowTech headers are designed to improve engine breathing, resulting in noticeable gains in horsepower and torque. The long tube design provides superior exhaust scavenging compared to stock manifolds, while the quality construction ensures reliable performance for street-driven vehicles.

I just bought two of the new Aeromotive pumps from autoplicity at the best price found online.. They were shipped out quick and arrived even faster than I thought. Autoplicity.com will be in my favorites when it comes to ordering parts for my 94 Supra from now on!!!

Great Seller. Fast Shipping and great prices!

Great price and great service highly recommended. Will purchase again

Good

I bought a Motive pressure brake bleeder from Autoplicity. I have been looking around for different prices for quite a while, and their price, even with shipping cost, was the lowest. After ordering, I received a notification of shipment and tracking number. The item arrived well packaged, complete, and intact within a few days. I am looking forward to using it.

Great prices, quick processing, and an overall excellent company
