sri and spi manifolds the same?

[JAMIEP]

Are sri and 1.4spi exhaust manifolds the same? cheers

[Ste L]

no, the sri one is a better design, and will give you an slight increase is if you use it on a 1.4 spi

[Adam]

As above.

THe SRi one goes from 4-2 branch with a twin downpipe.
Whereas SPI goes 4-1, with a single downpipe.
