For those wanting a 4 inch downpipe on your T6 S400...
LJMS has a flange available to make this an easy thing to do now.
100% CNC machined from Billet extrusions these flanges are available in both Mild and Stainless steel.
Designed with keeping Post turbine backpressure as low as possible as the primary concern, all cross section changes were done with smooth step free transitions to eliminate any and all lips/steps that may cause turbulence.
The register step width was picked to work with 14/16 gauge tubing. Input from some of the best welders in the country was used to select the perfect width shoulder so you guys have the right amount of material to have good strong welds to the tubing. The minimum thickness of the flange is .200 so its a robust piece to provide years of leak free sealing and service.
Along with the 5 to 4 inch reducer flanges.... I also designed flanges for 5 inch pipe too giving you guys a much nicer piece to use than the flared tubing stubs that are currently available.
The 5 to 4 inch reducer flanges are 29.99 in mild and 69.99 in stainless.
The 5 inch flanges are 14.99 in mild and 34.99 in stainless.
All 4 flanges are in stock and available now!! Tell me you saw it on Ls1tech... and I will give you 10% off.
