This 7"dia system is perfect for a road car. It is the same diameter as the Lotus Stg3 system but many complain that exhaust has a dronnnnne problem - there is no drone with the 2bular.
Supplied with the same OEM-sized oval tip with perforated lining - looks the part as well as sounding good.
If you are enthusiastic trackday driver, or just want a quieter exhaust, you will need the larger 8"dia 2bular system. This bigger diameter is strongly recommended if you are fitting the 2bular 4-1 manifold and catalyser.
SELECT SIZE: 7" Diameter OR 8" Diameter
