Overview:

Flowtech headers are the perfect combination of performance and value. Flowtech long tube headers are precision engineered using mandrel bent tubing, formed collectors and 5/16" flanges with sealing rings for a leak-free seal. All mounting hardware and gaskets are included for a simple installation. This header is coated in a high heat resistant black paint for a stealthy appearance.

Features:

  • Improved Exhaust Scavenging for Increased Performance
  • Leak Test For Max Performance
  • Mandrel-Formed Power Plenum
  • Leakproof O-Ringed Port Seals
  • Include All Mounting Hardware
  • Constructed of .049 cold roll flash mild steel tubing
  • Precision engineered for fit, performance and economy
  • Will not fit with manual transmissions
  • Will not fit C6 transmissions

Fitment Notes:

  • Will NOT fit with manual transmissions.
  • Will NOT fit C6 transmissions (but fits other Automatic Transmissions).
  • 351C-4V engines only!
  • WILL fit models with AC, Power Brakes, and Power Steering.
  • Breaking in an engine with ceramic coated headers WILL result in damage to the coating and will VOID all warranties. Ceramic coated headers require several heat cycles to fully cure before they will withstand extreme heat. Flowtech recommends using cast iron exhaust manifolds or old headers to break in new engines to avoid coating damage.
  • The use of header wraps can cause the header tubes to crack or rust due to excessive heat and moisture build-up. Flowtech does not recommend the use of header wraps as this will void the warranty.

BULKY & BUCKLING HANDLES
Color: Tan
The handles are bulky, and the leather buckles where you normally would hold it which is very uncomfortable. If you try to use the shoulder strap, the handles don't come off and get in the way when holding the purse against your side. Unfortunately, I first used it well past the eligible return date. I'm so disappointed. I would not recommend this product.

easy to access interior with many different pockets
Color: Desert
The back pack is awsome. It's soft, elegant and fits a lot of items...can be used in lieu of small carry on. I liked the openness of the interior area. The inside utility clear pouch was only 1 pouch, not 3 like the video. But I like it better with 1 pouch which leaves me options for larger items. The shoe pouch can be used for other items instead of shoes, if your interested.
