Hi all, I'm just wondering how much cat bypass pipes are for my 3S-GE auto altezza? I've read on this forum that the AT needs two, but don't know where the best place to get them from price wise?

Any ideas much appreciated!

Cheers,

RJ

P.S

Around how much HP will be released?

RS200 5AT has 2 cats between the exhaust manifold and the centre section of the pipe. It are also 2 Lambda sensors, one after each cat. The 6MT only has a single Lambda so the pipe for that is no good for you.

AFAIK the only people who make the decat section for the 5AT are RS-R. As for power gains probably around 5-10 BHP.

Thanks for the info mate.

I would like to get this sorted but with the two sensors I don't know how it would work with the sensor reading changes for the ecu without the cats.

I love my tip tezza but I really wish I'd bought a manual!

Cheers,

RJ
