£100 plus vat from qst, will report back on any difference as soon as they are fitted ! [img]images/graemlins/clap.gif[/img]

What is it going to do for your car?What happens at MOT time? I was possibly going to get the Miltek cats.....

should give small gains 20 bhp'ish ?!? sounds should be changed for the better but mainly its a start as i am getting milltek exhaust and dahlback cone filter and a re-map [img]images/graemlins/thumbs.gif[/img]


MOT time cats can be put back on, or see a good friend at mot test station and get him to back his vectra on to the emissions computer [img]images/graemlins/033102scull_1_prv.gif[/img] [img]images/graemlins/033102bigblink_1_prv.gif[/img] [img]images/graemlins/033102scull_1_prv.gif[/img] [img]images/graemlins/033102bigblink_1_prv.gif[/img]

Do you have to have it remapped when you put the new pipes on? Just that mine has already been remapped...

It hasnt been mapped yet, i will get it done when all is done exhaust, air filter and de-cats.

Fitted them took about 1.5 hours after cutting a couple of bolts off with a grinder. no noticable gains i think but apparently sounds a lot more ..............................wait for it.................. whooshhy ?!?

when i let him drive i must admit its sounds .....whooshhy anyone know what i mean ?
just need a milltek to finish it off [img]images/graemlins/thumbs.gif[/img]

Can you just cut the CATS off and put a straight thru pipe? Does it require any re-mapping. I dont want to re-map but need to know for future. Sure my car has had leaded fuel in it,s lifetime. I hear the lead blocks the cats quickly. Thought removing will be less restrictive

MOT time if the cats are not removable/replaceable my mot man wont get me a pass. covering his back i think, so i opted for the de-cat pipes which can be reversed with ease

If you take away your cats and/or change the pipe you dont need to do a remap. After all MAF measures the airmass engine sucks and by that info engine gets the fuel it needs.
If you have changed your pipe (I recommend BN-pipes) and are de-cating it, be warned that noise levels will raise a fair bit (It'll get NOISY, that is). But the sound will be so good that you will love it...
