Overview:

These Flowtech cast iron exhaust manifolds have a 2.25-inch outlet, natural cast finish, and are designed to hug close to the engine block so they fit into a wide variety of replacement and engine-swap applications at a budget-friendly price. Being cast iron means they will provide years of leak-free performance with less under hood noise than traditional headers. Plus, their shorty design means you can route exhaust tubing close to your frame/floor pan for maximum ground clearance.

Features:

  • Intended for GM LS engine swap applications where durability and leak-free sealing is desired at a budget-oriented price
  • 304 stainless steel mating flanges included (mating flange fasteners are not included)
  • 2.25 inch outlet diameter offers improved flow for maximum performance from a cast iron exhaust manifold
  • 2 bolt exit flange configuration matches the E-rod exhaust manifolds for a factory like fitment. This allows the use of OE gaskets and fasteners if desired, for an OE quality seal and fitment to emissions devices
  • Cast from Hi-Silicon-Moly Ductile Iron to provide durability and corrosion resistance
  • Tight tuck design provides universal fit for most popular chassis and a clean traditional muscle car appearance
  • Available in plain as-cast finish or with black or silver ceramic coatings for reduced engine compartment temps and improved corrosion resistance

Application:

  • Universal

These boys, as i affectionately call them, are adorable. I have to wait til April but wanna start wearing them now. Couldnt ask for better. I am eternally grateful for the help Saucony gives me. I wouldn't be alive without my workouts and they know it. Thank you and I bless you. ❤️❤️❤️🕊️🕊️🕊️

Nice shoes, good price.
Size: 4 Big Kid, Color: Mint/Purple
I ended up sending these direct to my kid at sleepaway camp and thankfully they fit well and have stood up well despite her rugged use of them. Most impt to me, they have RUBBER soles, not that cheap styrafoam mascarading as a sneaker sole.

Run Large
Size: 2 Little Kid, Color: Turquoise/Navy/Purple
We love the Saucony brand for quality, but my child felt the Saucony boys Velocer a/C (Little Kid/Big Kid) ran large. She is a true 2, but the 2s fit too long in the length and width so we returned.

Laces coming off
Size: 5 Big Kid, Color: Blue/Turquoise/Pink, Size: 5 Big Kid, Color: Blue/Turquoise/Pink
Cute and comfy but the laces are coming apart after two weeks of just wearing them to school and home. We got a measly 10$ refund for our troubles 😑

Are holding up great, but needed the wide
I bought these shoes for my daughter to wear to kindergarten. They wear navy uniforms and she loves pink so I thought these were perfect. I ordered her size according to the size chart (but didn’t check width because she’s never needed wide shoes in the past). The normal width were too tight on her toes but the length was right. I returned them for the wide and they are perfect. 2 months into school they still look brand new. Just be sure to check both length and width. I printed a measuring guide from Saucony’s website.
