LS Twisty Jet Boat Headers. These are 304 stainless steel with 1 7/8" primary tubes to a 3.5" collector. I have materials to build 4 more sets ready to go, so let me know if you are interested in a set! These were built for Steve Guedea out of Lake Havasu! Enjoy Steve!

180° BBC Headers built for Tanner Coldiron
This is a California Cool hull running a very mild built 454. Here are some pictures & videos of the final product & building process! Side note, this engine is only revving to 4K rpm so the exhaust will sound much better once he gets it to a higher rpm.

Always wanted to build some of these headers & I know these aren't everyone's style. Spent a lot of time trying to get these layed out planning as they were a challenge to build.

This set turned out awesome & features :
- Stepped Primary Tubes
- Merge Collectors with custom tips
- Individual Flanges
- Sequential Firing order (each collector fires in sequence with engine in a circle)

Thank you to Stainless Headers & the team for helping support me on this build per usual!
