If it is the heat shield you will probably get the "noise" at a certain rev range. Mine used to be really noticable as I slowed down. There are 4 bolt holes which can split from main part of heat shield, or the thing can also split anywhere and vibrate. I've now had mine welded twice (cheaper than a new one) and fixes the noise until the next time! Anyone with a welder should be able to help if it's the shield. Tap it hard and see if you get a noise!

3.3 Exhaust manifold heat shield
Heat shields were a common fault on pre-'97 cars, as these cars do not have the tray under the engine bay. It is possible for road water to splash the very hot shields caused them to fracture. They then resonate, as the two sides of the crack vibrate together. This is a warranty fix, but if it's the one where the left and right side pipes join, (by far the most common one to fail - this is a very hot area) then the dealer should pack the lower shield out by 3mm. This lowers the temperature of the shield and it will then last much longer, if not forever. The owner who came up with the 3mm spacer trick had got through 3 shields in 15,000 miles and was used to driving a car that buzzed. It has never failed since.
