-The E51 has what is known as a Quad-Cat system. This means that there are 4 catalytic converters in total. Two for Bank 1 of exhaust manifold of the V6 engine, and then another two for Bank 2.+The E51 has what is known as a Quad-Cat system. This means that there are 4 catalytic converters in total. Two for Bank 1 of the V6 engine, and then another two for Bank 2. This applies to both the VQ25 2.5L and VQ35 3.5L engines
  
-The issue from this system is that over time the first catalytic converters from each bank can deteriorate over time and can break down. The debris from the broken ceramic material then created blocked in the secondary catalytic converters further down the exhaust. Once a blockage has occurred, pressure builds up, exhausts gasses and debris can back flow into the engine and create terminal damage to the engine.+The issue from this system is that over time the first catalytic converters from each bank can deteriorate over time and can break down.

 Some owners have luckily had warning signs which allowed them to react and fix the issue before the engine died. These symptoms can range from rattling sounds in the exhaust area (under the cockpit), drop in revs, low power etc. Some owners have luckily had warning signs which allowed them to react and fix the issue before the engine died.

 =====General FAQ====== =====General FAQ======
 +====Underseal====
 +All Elgrand's are imported to from Japan. In Japan, they do not salt the roads in winter which means their vehicles do not require undersealing, although vehicles that were from regions of Japan close to the coast may already suffer from signs of rust (salty sea air).
 +
 +Depending on where you live in the world, your country may salt roads in winter to help with ice. In the UK, for example, gritters are typically from around November through to February each year depending on weather conditions. If your roads are salted, and you do not underseal your JDM import, the salt from the road will spray up and will corrode any unprotected metal surfaces that it lands on. 
 +
 +Undersealing is the process of adding a barrier to the underbody of your vehicle to protect the chassis, components and body work from salt damage. This will help to prevent rust appearing on your car and allow you more years of trouble free motoring. 
 +
 +There are various types of undersealing systems. From cheap annual jobs, to more expensive long life applications. The method you choose is up to you. You can research the various methods and select the best that fits both you and your budget. But it is important that you do this. Do not leave your JDM vehicle unprotected from salty roads.
