There is no difference, it means the same thing and has two different types.
- The INTERFERENCE (or the TRI.Y) is suitable for better fuel economy, towing and low mid-range power.
- The TUNNEL HEADER, is suitable for maximum performance at high revs on modified engines, not for street use.
We supply most popular extractors such as Holden V8 HQ, WB Hi tech Headers, Genie HM Headers, Pacemakers, Modivators, and many more.
For more information on headers or extractors, talk to Trevor or Steven at Radiant Exhaust.
DON'T FORGET - Headers work fantastically on diesel 4WD.
