I agree with everyone else saying it's a cheap exhaust with lousy baffles. I had the same on my BMW 320 had the new exhaust put on sounded just like yours plus a rattle. I had it replaced did the same, the exhaust fitter refused to do anymore saying it was my motor at fault. So we came to an agreement I went to another exhaust fitter put on another exhaust and if it didn't rattle and burble he would give me my money back (he still wanted the exhaust back) so put a totally different exhaust on and it was fine and I got my money back

if the baffles arent rattling about, its fine, its just a cheap exhaust. overrun popping is totally normal, if you want a quieter back box, pay more money.
@retrorestore3 жыл бұрын
You seem to miss the point, the new box in August was fine until last week so they replaced it under warranty and said the baffles were loose when they took it off. They fitted the brand new box and straight away it was rattling on the way home. Its not the popping, its the constant sound like the exhaust is blowing and rattling when driving. A £200.00 exhaust shouldn't do that, even if it is classed as a cheap one so its not about a quieter exhaust note, its about an exhaust that is not fit for purpose.

@ahillvfr3 жыл бұрын
It’s the gas flow being restricted by the baffles building up back pressure then when you shut off the pressure is releasing giving the popping sound. Just poor baffle flow and not as it should be. You can’t beat OE when it comes to exhaust replacement or a good named aftermarket company like powerflow etc - I’m sure an email to a few companies might get you a free system if you make them a promotion video 👍 good luck.

Baffles slightly loose in the box as everyone else says. Up to you really, put up with it and hope that as it ages and the carbon builds it quietens or press for a replacement which probably wouldn't be any better as it'll be the same brand. If it's not leaking and isn't too offensive I'd live with it, if it's bad it'll fail within the year anyway and you'll get a warranty replacement.

If it only started after the exhaust was fitted then surely it must be the exhaust. Engine sounds fine and only doing it when over running you have pointed out why you think its not overfueling and I agree . Although it would obviously sound louder it would be interesting to know if it still does it with the back box temporarily removed.

Loose baffes in the back box but opels and vauxhauls in general are a bit burbly. Might have sticky exhaust valves. Do this next bit kinda quick, take off the back box and run it without the box and see if it still burbles. Itll be much louder of course but youll get a rough idea of if the back box really is the issue. Mightnt be any harm to split the box and see if anything is loose inside. Some of the aftermarket exhausts come with a plasticky thing inside for packing reasons that takes ages to burn off because the back box doesnt get overly hot

Can't hear it clear enough but usually when you get popping on overrun its air getting drawn in to exhaust. Only needs to be slightest pin hole leak in a joint or weld (get an assistant to hold a rag over tailpipe while you check by using a piece of hose as a stethoscope). Particularly check flexi and also around manifold (could be cracked & manifold constant with both exhausts). As already said remove back box to eliminate from suspicion. Dismiss the overfueling (unless they can give you facts!) as you said the engine light would have come on by now.

I think it's the backbox. My mondeo mk3 tdci just recently had this issue where the backboxs rear pipe (where air comes out) fell off because of rust I guess. (14 years old, what to expect - was the original) Somehow the cars turbo is faster to spinup plus might even be more economical now and also it sounds a lot better now :? I am going to get a new replacement because of danish mot laws, but will be sure to get a good quality one, because if you cheap out they do not last as long and you will end up like your vectra in a short time sadly.
