Performance Exhaust Issue...

[jamieb199]

Im recently put a 2.5" cobra resonator and back box on my is200

I want to put a high flow cat and manifold on it but cant find any.

Can anyone recomend some or a way to fool the 02 sensors?

Cheers

Any custom exhaust place will have high flow cats. Just make sure you research them properly first.

I have asked them but they dont do cats ir manifold for the is200

[Stuno1]

Really? They should have high flow cats for all bore pipes.

'Cats ir manifolds'?? Also, same with manifolds mate.

If your local 'longlife' place is good they will do it.

Cats for*

Cheers fella ill have a look

On the manifold iv heard they are "pre cats" is that tre or bull?

Apparently using a decat manifold wont bring on the eml light

They will definately be able to sort a sports cat to replace the normal one.

For the cats on the manifold, i dont know if there is a 'high flow' option. As far as i am aware it is just with or without.

Without will trip the sensor you are speaking about. I imagine you can deactivate this easily enough.Usually by removig the associated fuse. I would go on the US forum 'club lexus' as they are crazy about mods and will definately be able to help.

Wicked cheers for the advice fella!

No worries pal.

The pre-cats are only there to speed up the warm up. It is quite a common mod to open up the manifolds, remove the pre-cats, and weld shut again ;)

As for the main cat, as stuno1 says, there are plenty of places that will fabricate a custom exhaust and that can include the main cat if you pay for it.
