Blayne Posted December 9, 2016 Report Share Posted December 9, 2016 Hi guys. Recently my back box snapped off due to corrosion, so I left it for a bit because it sounded ok without it and didn't really have money to sort it out yet. A couple of weeks later I pulled away and the cat seemed to take a lot longer to accelerate and also the engine sounds a lot louder. Now is this due to there being no back box on it?

Rich Posted December 9, 2016 Report Share Posted December 9, 2016 it has probably snapped further up the system now. Quote Link to comment Share on other sites More sharing options...
mk2 Posted December 10, 2016 Report Share Posted December 10, 2016 If you have some tools, check the air filter. You can get a new one for a fiver online... But rich is right. If its even noiser, there maybe another break. A complete new exhaust (without cat- you don't need one usually) you can get delivered to your door for about £55. It is possible to change it on the cheap by driving the car up a high kerb keeping two wheels on the road. Then with some cardboard, a torch and a junior hacksaw you can get under and swap it. But a hoist is much easier. I remember when I was a student... Quote Link to comment Share on other sites More sharing options...
