Fitment Notes:

  • Pontiac V8 Engines Only!
  • Will not fit Firebird/Trans Ams with column shifted standard transmission.
  • Must modify stock exhaust to retain catalytic converters.
  • Will not fit Ram Air vehicles.
  • End holes on head must be drilled and tapped to ensure proper seal.
  • 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 recommend 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.

Really like these for casual summer outfits
Size: 10.5, Color: White
These are really nice kicks. Stylish, comfortable, and eye catchy for sure. Not too heavy, good price, and fit well. These are great, casual white shoes for a summer outfit. I gave it 4 out of 5 stars as these do pick up and hold onto dirt and smudges more than I’d like to see. Yes, I know, white shoes are magnets for this stuff, but these tend to scuff and discolor more than I would have assumed. I live in an area with lots of bad weather most of the year so I only get a chance to wear them for a few months of the year unless I want to brave the wet and muddy weather. If you live in an area that has lots of sun and are willing to put these to the test and clean them often, I would say go for it.
