He was looking into why there seemed to be a leak from the exhaust manifold where it joins to the extractors.
Damian looked under the car and noticed that the fitted exhaust had sagged considerably - sadly he didn't think to take a photo of it, but this is how low it was after it was first fitted...
Note the lack of ground clearance below the green cross-member.
It had sagged a good 1-2 inches lower than that - you couldn't even roll a can under it!!
Damian took Booger Mobile to a different exhaust shop (Burpengary Performance Exhausts) where he asked for the exhaust to be fixed. Ground clearance was key, and the issue with the leaky manifold/extractor gasket needed to be resolved.
The problem with the leaky manifold was simply caused by a bent bolt... You can see the slight bend in it below - this causes it to tighten up even though it's not actually pulled the extractor tight up against the manifold.
It was also deemed that the existing muffler wasn't suitable - it was a 1 and 3/4" muffler on a 2" system - apparently this would cause the engine to run hot... hmmmm....
The muffler was also moved from in front of the rear axle to it's correct location between the rear suspension and the fuel tank - this allowed for it to be tucked safely up out of the way!!
Check out the massive gain in ground clearance!!
And the view from the front looking towards the back is breathtaking - look at the ground clearance!! No part of the exhaust pipe or muffler is lower than the rear diff.
