T1R 70R Dolphin Exhaust for 06+ Civic Si Sedan

The “Dolphin” aspect of this T1R exhaust’s name comes from the shape of its tip, but this piping set up is about more than just the tip.  It has a 70mm diameter for high flow and the walls of the pipes are only 1.2mm thick making it pretty lightweight.  It features a deep sound but still meets regulations so you don’t need to worry about the cops (too much) with this set up.
