These are a full length set of TRI-Y headers made of 14 gauge mild steel (.083 wall thickness). The header flanges are 3/8" thick CNC laser cut and machined flat for a leak-free seal. The final collectors utilize a ball-socket flange for easy hook-up to the custom, bolt-in Y-pipe.

The headers are available with either 1 5/8" primary tubes for normally aspirated applications or 1 3/4" primary tubes for forced induction or stroked motors.

You will also be pleased that we take the extra time to polish all clamp marks and do 100% welds around all the primary tubes. This takes approximately 45 minutes more to manufacture but the results are worth the effort. Our competition does not take the time to do this.

As a result strength is lost, water may be able to get into the seems around the primary tubes which could cause rust and over-all the headers are less visually appealing. Our prices are also less.
