Wortec blowing monaro vxr 6L

[Madgehsv]

Have noticed a light rattle from the drivers rear side over last few weeks. Tonight ive spotted condensation dripping from where the rear box joins the middle pipe. Also I can hear an obvious"blow" from that area. Could this be just a knackered gasket? Exhaust been on for 7 years and 45,00 miles. Cheers

Condensation will happen in every exhaust, and with the slightly acidic exhaust gasses will rot even the best stainless steel over time - so
I would think that the rattle is the baffles inside one of the boxes coming loose.

If you've got a drip from a joint, then I would think the gasket has failed. Replacement gaskets are cheap. Just make sure you clean up the exhaust faces before fitting.

Traced down to the clips. Both have rusted and fractured. Thankfully Monkfish have replacements

Well this is getting more complicated.
Go today to replace the clips joining drivers side rear box to mid pipe and found that the joining ends of rear box AND mid pipe have rusted to the point the back box Separated completely from mid pipe. Spoke to MF but Wortec's warranty is not owner transferable. Disapointed to see a high end exhaust completely separated due to rust affecting two separate sections. The rest of the exhaust both sides appears in good condition. Appears the joining ends are not 100% stainless steel. Intend to politely voice my concerns to Wortec although i cant see any contact number on their web site. Guess i need to try and find a decent welder to cut out the rust and replace with stainless steel? Any other ideas?

There's an e-mail address on their website [e-mail]

You could also put a post on their Facebook page. https://www.facebook.com/pages/Wortec/102175946507...

Mines done exactly the same thing on both sides. See picture for the worst one.


I daren't take the clamps off incase the whole thing crumbles in my hands

[Magic919]

Does make you wonder whether it's some kind of galvanic corrosion between the clamp and exhaust.

[Madgehsv]

Ahh so im not the only one. Im not mechanically minded really, but an exhaust system sold as stainless steel which corrodes at 7 years when the car has always been garaged and carefully looked after don't seem very right. Added to the fact that when you place a magnet near the ends of both back box and the ends of the mid pipes(where the corosion is) the magnet sticks, suggesting to me its not 100% stainless steel?

[Magic919]

There are numerous types of stainless steel and they suffer corrosion to varying degrees. Trouble is, the general public equate stainless steel with never rusting.

[Madgehsv]

Spoke to a chap at Torque Technique who has done work on a few monaros with Wortec's fitted. His plan is to remove the 'y' shaped end and replace. Booked in Wednesday 0830 for day job...

^^This. If you Google 'Is stainless steel magnetic?'....or something similar you will be presented with a range of differing compositions of stainless steel, some being magnetic and some not. Far too complex for my mind though.

[stevieturbo]

few stainless exhausts would be totally non magnetic


As for the rust/problems, surely Wortec offer a lifetime warranty against that sort of thing ?

A neodymium magnet will happily stick to 304 stainless.
Given enough heat cycles and vibration, I'm not surprised that stainless steel systems will eventually suffer........

[Madgehsv]

The Wortec guarantee is only covered for the person purchasing the system. Its not transferable to a new owner. That said the car is used on motorway, stored in in-house garage. Suprising how it fell apart after just 7 years. My intention is to make my concerns known to Wortec. Im not asking for anything, but feel I need to let them know how badly corroded this system is.

[Magic919]

I'd expect the stuff flowing through the exhaust would be the greater cause of any corrosion.

[Madgehsv]

I get that. I guess when we look to buy a car such as a monaro we look for a car with specific things. For me it was a standard vxr with just a Wortec upgrade because of the sound but also the fact it was an expensive system which I believed is of quality stainless steel, and hope it would last more than 7 years and 41,000 miles. I accept stainless steel is not going to last forever, but after 7 years for it to literally drop off? And that's where lies my disappointment. Surly anyone who has either bought this sysyem or indeed bought a monaro with this specific upgrade would be Disapointed in it dropping off after just 7 years?

[Magic919]

I agree with that. Paid about £3500 for mine about seven years ago and I'd hope it is still going strong all these years later.

I honestly don't know what would be deemed acceptable for the service life of an exhaust, but I can understand your disappointment.

Wortec just design the thing and Janspeed make them as far as I know. Wortec should be in a position to comment on materials specified and what kind of service life to expect.

[stevieturbo]

If the exhaust has corroded and failed, then absolutely no way is that acceptable.

If it was a fracture or break, you could maybe deem usage, mounting etc as a possible cause and maybe have less expectation of warranty.

I've a stainless Maniflow on my Mini for over 20 years and it isnt as bad as your after only 7.

And Wortec is not a cheap system by any standards.

IMO any good quality stainless exhaust should outlast the vehicle in terms of corrosion, without question.
Other aspects may fail or give problems, but they should not be corroding to the point of failure.
