I have a GT35R w/ the .82 precision exhaust housing.The precisions outlet is 2.5 and the Garrets housing is 3 inch.

Do u guys think this is a power loss?
I was told the inside of the Garret housing is also 2.5 inch but then enlarges.The PTE housing is 2.5 straight through.

Is it worth getting the garret housing, or will I not see a difference in power from switching?

 

What, nobody has a reply to this?

 

Need to know also.

 

I like the design of the garrett Housing because it creates a better transistion from the exducer of the wheel to the ID of a 3" downpipe. the "diverging cone" housing helps extract a bit more turbine efficiency by reducing turbulence on the outlet of the turbine wheel and by creating a slightly lower post turbine pressure.

 

go with the pte housing.. there is no power loss the neck on a gt houing expands into a 3 inch but it also limits your room for dp.. my friend has a gt30r with gt housing and we cant run a big radiator on a ram horn manifold... pte houwer doesnt stretch thse few inches and giuve you more room for fitment..

 

so really, U arent going to lose a considerable amount of power by using the PTE housing and the precision housing is only 175 compared to the garrets 300 something.
PTE told me that there is not currently a flange produced for the Garrets 3inch outlet, is that true?

Anyways, Precision it is, thanks guys.
