Hi all,

Just out of curiosity, has anyone else had this problem...

I recently had a new backbox fitted onto my Corsa b. It is a standard cheap backbox, nothing special. Anyway.. I drove my car home, all was fine. Then, I took my car out to the supermarket on quite a long drive. As I'm driving along, I start to hear a dodgy loud banging noise coming from where my backbox is.

I get the car home & check it out. Nothing seems wrong.

It turns out that because the backbox is cheap, the fittings are longer than normal. The mechanic explained this to me & tried to rectify it. No luck. As the backbox got hot, it expanded causing the fittings to tap against the back of my bumper area. This really sounded dodgy in the car. Having the fittings chopped down a bit on Tuesday.. thank god. :laugh:

Anyone else had a similar problem?

Well kind of....but in a different place and for different reason.

When I fitted the 1.6 into my SRi, I left the downpipe/centre section from the 1.4 intact. Just this afternoon, I've had to take the car to have the tracking checked over (still fine) and had them put a new rubber mount near my cat. The 'lip' on the left side of the cat has been resonating against the underside causing an awful rattling when idle :mad:

Did it sound like a woodpecker Lyds? :laugh:

Only when i go over big speedbumps a tapping noise always happens when going over them, I wasnt too sure what it was but I went in my mates corsa and it was exactly the same noise.

I think its the exhaust hitting the axle for me though :confused:

Lyds, a guess is it sounds like it's not pushed on far enough at the join to the centre pipe.

Quite a common problem with fitting new exhausts is that that bang on the axle, its because they hang too far down and move around a bit, i managed to rectify mine with a couple of cables ties so its not so loose and wobbly :)

Lol, it's just as easy to unbolt the securing clip, hold it higher then bolt back up really tight. Works every time for me.

Yeah my dad suggested having it pushed back onto the pipe further. But I think the mechanic is going to chop down the fittings for a couple of cans of Carling :thumbs_up: He's a good bloke by me.

i improvised when my backbox was hanging too low, i turned my rubbers round, put both sets of hangars in the centre hole and then stuck a cable tie around the rubber, sat perfect now, no wobble

just by shorter stiffened rubbers to stop the wobble only a couple of quid.:thumbs_up:
I've done that. It's not the rubbers. It's the fittings being too long mate. I replaced all the rubber exhaust mountings - no joy. The mechanic will sort it!
