Made in Canada
CTS TTRS/RS3 4″ High Flow Downpipe features a CAD designed 4″ T304 stainless steel V-band flange and turbo outlet.
For optimal clearance between the downpipe and driveshaft, the downpipe splits from a 4″ design to a dual 2.5″ design,
where two additional stainless steel flanges fit seamlessly into your stock or high flow center pipes.
The downpipe was developed using CAD simulation and designed so that the exhaust flow is evenly distributed into both exhaust pipes.
Each downpipe is handmade by CTS to order and tested in a hand-built jig,
to ensure an exact fit.
