An Engineered and CAD designed 3" downpipe with fewer bends yielding the smoothest exhaust paths possible. These downpipes really maximize exhaust flow resulting in quicker turbo spool up and much less lag.

Dyno results have shown 20-30whp gains!

By making downpipes bigger and reducing back pressure after the turbo we effectively make the turbine assembly easier to spin since there is less resistance (back pressure) on the blades. That equates to faster spool up and less lag across the rpm range.

We utililize 200cpi metallic substrates in our catalysts for the ultimate in flow, while providing you piece of mind when it comes to emissions testing and OBD readiness compliance. These cats flow so well we use them on our shop ASP S4 making over 900whp!
