exhaust bore size

[devil84]

Is there any issues with mating a 2in inlet backbox to a 2.4in b pipe.

or is best to keep bore size consistent all the way through ie 2.4 and 2.4

Trouble is - there is not many 2.4 inch backbox around, all 2.5inch backbox. I heard if you go bigger - you loose back pressure and therefore lose low down torque.

Can someone advise?

Nothing to worry about here unless you're running serious power.

Okay so no issues having a 2.4 b pipe mated to 2inch backbox. My power is around stock bhp.

No issues at all.
