mongoose bore size

[EssexAaron]

whats the bore size of the mongoose systems. is it 3inch?

is the downpipe bore size the same as the rest of the system. cheers

 

[pulsarboby]

think its 2 1/2'' id the downpipe is the same size as the back section

I think the internal diameter of the mongoose pipe is a disappointing 2 1/4"

Aaron, a Mongoose is 2 1/2".

The front pipe i've got was custom fabricated and is 3"

A good set up would be a 3" front pipe into a Mongoose 2 1/2" system as the bigger front section allows the gasses to exit the turbo quickly then speed up through the 2 1/2" system.

where the goose front pipe bolts to the turbo elbow its only 2.1/4 inch.from there its 2.5 but the very first part of it is a bit on the small side.
