I know this has been done to death but I have a small question. The heat shields are removed are there any feed back if this has caused problems.

In my opinion, the manufacturer would gladly leave the heat shields off if the standard exhaust didn't cause a potential problem. I'm pretty sure that a non-standard exhaust that is closer to the parts that are shielded will cause a problem much more quickly.

Remove them if you don't mind catching fire when you least expect it.

Mate; are you talking about the heat shield/s on the exhaust manifold or the one under the floor pan, just above the muffler?
Mine has a 3" system with only a small hotdog muffler. The original heat shields are still in place and I can't imagine any advantage in removing them.

Dozer,

I thought the same thing, but then, realising he is a member, I checked his rig profile and found he has a Patrol 4.2TD (same as mine).

We had a 3inch system fitted to our 4.2T and we replaced the heat shield around the manafold ourselves. The exhuast system certainly improved the performance of the car.

When I changed my GU 4.2 TD exhaust to 3", the heat sheilds where removed and I had the section that goes under the cab High Performance coated, keeps the heat in and not into the cab, works well.

I left the heat shield off the piping for my MTQ 3" system. Partly as it was a bugger to put back on but mainly as it was causing premature corrosion (rust) on the original exhaust after only 35,000k. I thought this was a much bigger issue for problems later on.

The shield on the dump pipe and turbo was put back on with the holes moved a tad. The mounting holes pentrate into the exhaust flow so the bolt must go back in at the very least.

Have had no issues with heat at all but it is a little noisier but still no problem. The Original heat shields were packed with an 'asbestos' looking material that trapped the water and I think that Nissan's maini aim was to reduce noise rather than heat. This stuff trapped water and hence the rust.

I'll post if I have any problem with it setup like it is.

cheers
