Call me stupid guys but what's the difference between cat and turbo back?

Hi, I have recently bought a 2012 facelift 1.7cdti, I bought it with front end damage, and am currently sourcing parts for the repair.

Is there any difference between post and pre facelift headlights? I thought it was just the front bumper that differed however now Ive started looking I suspect the headlights may be different in some way?

Problem I have is I dont have the old headlights for reference as theyre in a million pieces

Any help grately appreciated

whilst my anoying husband has been driving round the countryside really slowly (he drives too slow in his old man berlingo flappy paddle auto).

as he tends to listen to 1960s music and i want kisstory or absolute 00's, ive been listening to my music via my phone and my headphones in one ear, ive been keeping an eye on when the dab stereo says its lost signal, we have been in the middle of nowhere in mid wales, no fm, no dab but weirdly my app radio never missed a beat.

Are 5 door astras built better or the same as gtc.s?

The reason i ask is,  i hear odd moan about the astra j,s  build quality but I hear loads moaning about the quality of the gtc and astra estate mostly about paint quality , am I right in thinking the gtc and estate are built in poland,

Hey guys!

Recently picked up a 2013 GTC (1.6 Turbo 180ps) and I am currently looking into smaller tuning options, at least for now anyways.

After looking at cone filters, I've pretty much ruled them out due to the limited amount of kits out there, the price of the kits available, the effort of making one myself and heatsoak issues.

So back to the question, as far as I know the Pipercross is about £15 cheaper and is a dry filter, vs the K&N which I believe is oiled.


So all I really

Am looking at changing my interior for leather at some point.

So I know what I can and can't buy is the 3 door Astra interior 100% identical to GTC interior or are there subtle differences please?

Thanks in advance for any info, tips etc. 

right then I currently have 2 astra Js
one is a 12 plate (non facelift) 5 door SE with the cd400
other is a 61 plate SRI sport tourer with the Navi600 (with BT and Dab+)

my question regards the audio volume - the CD400 is much louder - does it have an amp or something that the Navi600 doesn't?

and if it does - can I fit one to the Navi600?

any ideas or suggestions??

Hello all,

I'm in need of a new headlight assembly on the driver's side of my 2013 J Sports Tourer (A16LET engine & standard non-Xenon non-adaptive headlights.)
I'm browsing through listings on eBay etc, however there seems to be a distinction between 'Sport' and 'non-Sport' models when it comes to compatibility. 
I'm a bit thrown by this as I'm in Australia where the J was sold under the short-lived Opel brand with no 'Sport' model in the lineup. Can anyone shed a bit of light on what a Sp
