2008-2009 g8 gt/gxp high flow catalytic converters (BOLTS FACTORY MANIFOLDS TO CATBACK)
Unleashed!!  This is what these cats do to the Pontiac G8.  The exhaust note becomes RAW with a huge burble on decel.  The best part is that there is still not even a hint of drone with any of the Solo exhaust kits.  The drivability is dramtically increased, as the car just keeps on pulling and pulling.  These deliver raw performance as well as raw sound!  We were surprised to see that Pontiac had decreased the internal size of their cats to 1 3/4" on the inlet side.  We suspect that they did this for sound control.  Solo cats are a full 2.5" all the way through.  They use a heavy duty flex pipe and laser cut stainless steel flanges along with all stainless piping.
