Finally found a pre cat pipe for the vectra 1.9 cdti.

gonna get it fitted in next few weeks, already removed main cat when i had new twin exit exhaust system fitted, and that made a difference, and nice little turbo whistle, fit pre cat then off to Courtney for a remap. Happy Days

How does that fit on as on my veccy the precat is all one integral price from turbo to flexi and that looks alot shorter than the pipe fitted to mine. Are you going to fit it your self

No pipe fits fine it is only for the 1.9cdti engine, pre cat might be different on others! mate is fitting it, he is a Vx tech at dealers.

I had one of these fitted las month. The garage that fitted it for me had 2 problems. Firstly, the hole for the probe is on the wrong side. Luckily the garage sourced a bolt in bung that fitted and they cable tied my probe up out of the way (this must be for the DPF as i've had my software removed and no errors appeared after they tied it up). Secondly, the end that butts up against the turbo was a slightly different size, or shape, as anytime i was pulling up to a junction i was getting exhaust fumes sucked into the car. It's been back into the garage and they've 're-sealed' it, don't know exactly what they've done, but it's spot on now.
Can't say it's made any difference, the car is going on the rollers next month, we'll see then.

Or just drill out the pre cat which is what I've done. It looks standard costs nothing and get te same gains my pre cat is now hollow with my hollow dpf it's basically a straight through system now only need to remove the rear silencer is my next task

The DPF is only fitted to the Estate and Signum so if yours is the hatchback/saloon then the probe is not for the DPF

So there is two cats on the 1.9cdti 150?
I had the one that was fitted after the flexi joint removed when I had a full exhaust fitted.
Need to get my car on the ramp again and have a look. Is this pre-cat pipe only for cars with a DPF?

Believe the probe is the lamber sensor, maybe called something else but all 1.9 cdti's have them

doubt you will see any difference on the rollers

Cheers for the info Sparky28, so really the Lamba sensor should be attached and not left hanging then?

Whatever it's for, the hole is on the wrong side in the eBay ad at the top. Scorpion on list it as an Astra pre-cat de-cat. The Astra must have the sensor on the other side.
