Turbo down pipe

[LX_TREME]

For those running the Turbo,

Do you guys still using the same old OEM down pipe? Or maybe if you know anybody carrying the aftermarket 1FZ down pipe please let me know, and also what the pipe size...2 and 3 quarters or 3 in?

Down pipe – 2 pipes joined together right after the exhaust manifold and before the sensor and catalytic converter.

At least on the APS Safari one, the exhaust manifold is in two parts but still collects all six cylinders into one and then dumps immediately into the turbo - this is a T4 mounting surface-sized hole. The downpipe is just a single cast unit that mates to the turbo and makes an approximate 90-deg turn. I believe it's 3 inch diam since that mates up to the 3-inch exhuast flange (3-bolt style).

Have you considered just running them separate back to a single cat that has two inlets and single outlet? I know you're in CA but those headers aren't compliant so why worry about the cats?

i did a custom. 4 inch mandrel to a 3 inch curving under truck to 2 1/2 inch and then to the oe exhaust. a custom downpipe is way easy. just connect the pipe to the turbo with a v-band clamp.
