Re: Exhaust Issues 156 2.5
Usually it would be down to the lambda sensor failing, an exhaust leak won't make that much difference.
Oh and there is no centre box....
The first "box" is the Cat... next is the first box, and then the back box. If your leak is on or around the cat it coould be the cat that is knackered...On the plus side you can get a sports cat for less money than an original, and it should increase power. I would consider a st/steel system while your at it, as that will also increase power slightly, so I have just spent £600 for you...and you need to get your headlights done properly as they are lined up on a machine, most MOT stations would do this as a freebie, when I had mine re aligned a bulb had dropped out and sent the beam up in the air, so I fiddled and made it worse, got the boys at my local tyre centre to do it when they changed my tyres, and the only charged for the bulb, not the adjustment.
Hope this helps
