Scorpion Back Box - Fouling Rear Subrame/Axle?

[alexwitham]

Hi,

 

My 2005 350z has a Scorpion backbox fitted. It appears to be the cause for a metallic knocking/tinny sound from the rear of the car, it's definitely exhaust related. Has anyone else experiences issues with an aftermarket exhaust fouling the rear axle/frame of the car?

 

The rear exhaust tip is only about 1 inch away from fouling, so I'm assuming it's this section that's causing the issue.

 

Thanks,

 

Alex.

Have you had it on ramps to actually have a look? It could be the heat shield off the Y pipe of cats causing the same noise.

My scorpion back box came out 3/4 rubber hangers last week, all put back in fine but ever since it has been making a ratling noise like you describe, if I wriggle and push the tips around it makes the noise so I think when it was loose its moved something, haven't had a chance yet to have another look.

My scorpion back box has also started to rattle but only starts to do this after the car has been running for a while, I'm thinking it may be the exhaust baffler that has come loose inside. I'm going to take to garage on Monday .

Having said that It could also be the heat shield as I did catch the underneath the other day while going over a speed bump at Asda.

@gunny reed - Mine also starts to make the noise I mentioned generally only when the car has warmed up.

 

My cars booked in on the 21st, I'll update once it's been looked at - if you could update this thread too that'd be great!

Yep will do as soon as I find out ill let ya know, as said going to garage on Monday fingers crossed nothing but a loose heat shield.

Update:

 

Right hand muffler was fouling the axle, heated the brackets and bent it an inch, problem solved.

This is quite common with the scorpion .... It needs "tweaking " to fit right . Good sounding though
