Exhaust noise and leaks can be real annoying but often rarely viewed as dangerous , however as we all know exhaust fumes are extremely poisonous and should not be taken lightly.

 

Essentially any combustion fumes that enter the cabin area can soon become a recipe for disaster especially as it can not always be not detected, and also any exposure is culmative meaning small regular exposure can tot up to a lethal amount let alone headaches and drowsiness.

 

So bearing that in mind take a look at the photo's below, a zed with a very serious exhaust leak at the rear of the turbo elbow. The position if the leak is slightly forward of the bullhead and very close to the grommet where the ecu loom passed through and also the grommet for the air con drip pipe, any issue with these seals could compromise the cabin seal.

 

So the zed in question is a later model and has the pre-cat fitted on the passenger side and of course this is the side with the leak. The pre-cat makes removal that little bit less accessible, not impossible just more of a ball ache, doing this job on your back using a trolley jack would be an absolute pig so anyone who has done it that way take a bow!

 

Just a heads up for us all really, and of course due to where the exhausts resides it generally goes unchecked, maybe an occasional check on a ramp is a good idea especially if the exhaust has been fitted a long tine ago.

Pre-cat still attached to the turbo but the second cat and pipe removed.

 

 

Gasket failure caused the black /soot marking by the bottom studs

 

 

New and old gaskets side by side, gasket failure due to loose/ missing lower nuts

You should drive mine. honks of petrol and as soon as you open the window the exhaust fumes are nuts. :lol:
