      I had an issue in my last drive (sweihan) with lead @Asif Hussainwhere my car started withloud exhaust leak noise along with loosing power as it wouldn’t go beyond 5k rpm. 
      Turns out that the catalytic convertor had broken substrate which created back pressure on engine forcing it to cut power ( smart engine!) 
      On researching, I found info on how straight pipe exhausts allow for more engine power while
      1. Introducing backfire noise ( gunshot sound) 
      2. more pollution

      As an alternative ,its is also suggested to go for high flow cat from a reputable brand. 
       
      any insights into this Mod. @Frederic @Gaurav @Vanessa8580
      FYI , I drive the 2014 3.8 LWB PAJERO with 160k on the run.

      Thanks to @Hasan Wahlan, I found the trick to getting LandCruiser to climb up with power & ease is to shift it manually to L (in 4-High of course). Unfortunately I was too excited with this discovery and fear of getting stuck on the crest triangle made me step on the pedal a bit too much¬†ūüėā
      So my LandCruiser flew, as soon as it touched down @Srikumar bhai asked me to check the radiator. Radiator was ok and we continued... Two days later "clicking" noise started coming from the front-driver side, as seen from this video:
       
      Can you guess what the culprit is?
      If you say CV Boot close enough, it did start with the CV Boot leak, but eventually I had to replace the whole front-left axle¬†ūüėā¬† No need to buy new one though, new OEM will cost 2000dhs++ , since i may break it again *touch wood, a good second-hand that costs 400dhs is enough for now¬†ūüėĄ

      Driving off-road is very interesting and entertaining experience but there are few basic things you need to check first before heading for your first off-road drive with Carnity Off-road Club.
      Every driver should know when to join for an offroad drive and when to pass until all below things are checked.
       
      VEHICLE
      Ground clearance: Minimum 8-12 inches under front and rear bumper is must. If your vehicle has 8 inches then you should be careful while driving and slow down while descent and approach to avoid any minor bumper damage. If your 4x4 have EAS (electronic suspension), lift it to the max height and then measure it. Also read the manual to know what is the max speed you can drive with off-road height, as many manufacturer limit up to 60 Kmph with off-road height, which is plenty in most cases. Knowing that limit is better in case you go above that speed, so you can lift it again once you slow down.
        Tow hook: Your 4x4 should have at least 1 tow hook in the front and 1 tow hook at the back, more the better. Also you should check the integrity of all tow hooks and its appearance, if they are shaking or rusted or missing a bolt, then get them fix before joining any off-road drive.
        Engine: Your 4x4 engine should be in perfect working condition without any check engine light or any warning lights on dashboard or leaking oil or coolant. Engine takes more stress while offroading so well serviced 4x4 performs better on off-road. If you recently bought the car and have no idea of last service, then its highly advisable to get the engine service before your first off-road drive.
        Gear / Transmission: Your 4x4 should have LO and High gearing option. AWD or SUV without LO/HI gearing option, generally not advisable for sand off-roading. If you have extensive offroading experience to tackle such vehicles then discuss it on the forum with the trip leader and see if they can allow such exception.
        Suspension: Your 4x4 vehicle suspension should be in reasonable and drivable condition. You can drive with stock suspension perfectly fine and then you can decide to modify it, if really needed. Any suspension lifted up to 5-6 inches are accepted, anything above 5-6 inches lift need trip leader approval before joining any drive to make sure if you have widened the wheelbase to lower the center of gravity in an orderly manner.
        Tires: Your 4x4 tires should be in good condition with enough tread and more than half life left. Tires nearing their end usually fail while offroading, so check for date of manufacturing shouldn't be more than 3 years. No visible cuts or lost tread chunks or cracking sidewall should be there.
        Fuel Tank: You should always join the off-road drive with full fuel tank, as all vehicle consume double or triple the amount of fuel while off-roading. You don't need to change the fuel type from special to super for off-road purpose, continue with your fuel type as per manufacturers recommendation.
        Sign up: Once you have checked all these above points then RSVP the drive calendar and post an introductory message on the drive post - sharing your 4x4 details, previous off-road experience (if any), so that trip lead can acknowledge and plan the drive accordingly.  
      OFF-ROAD GEAR
      You don't need any off-road gear or recovery gears for your first off-road drive, but if you have a shovel, flag and a radio (walkie talkie) then please carry it with you. Rest all the off-road gears and recovery tools will be shown to you once you attend the briefing and you can read more about them here: https://carnity.com/advice/offroad/most-comprehensive-list-of-off-road-gears-and-recovery-tools-r81
       
      OFF-ROAD DRIVE
      Always wear long sleeve and closed shoes (no sleepers) to avoid any injury or sun burn. Carry hat/cap/scarf, in case you need to spend long time under the sun. Carry plenty of water and soft drinks of our choice to keep you hydrated. Carry your camera mounts if you like to record the drive (no hand held). No carrying or consumption of any type of alcoholic drinks on the drive.

      While offroading, we cross dunes by using different methods, based on how the dune is formed and what the drive level is. Once you have spent some time in the desert, you will slowly start to pay more attention to the dune formations and how we cross them. Once you reach Intermediate and Advance level, you'll need to start learning how to read these dunes in order to navigate and create your planned routes in the desert.
      As a rule of thumb, the prevailing wind in UAE is blowing from a North-Western direction to South-East direction from 10AM onwards. At night and in early morning it will be reversed and blow from the South-East to North-West.


      This is something you should remember and you will notice when you zoom into certain areas with your navigation app (Google Maps, Gaia, MotionX, Mytrails,...) you will notice that the wind from that side has caused the dunes to take on their shape. This is a general rule and will not always apply, as you will see that in certain areas where wind is coming from different directions, you will see for example "star" dunes appearing.
      There are different types of dunes which are separately described below.  As you can see in below picture, a dune is formed when the prevailing wind blows on a mound of sand, where the grain will move into the wind direction and create a ridge. The sand which falls on the other side of the ridge, creates a slipface, and this sand is not compacted by the wind. This is the main reason why we generally drive on the prevailing wind side or the convex side of the dunes on the Newbie level.
       

       "A dune is a curiously dynamic creature," wrote Farouk El-Baz in National Geographic. “Once formed, a dune can grow. It can change shape and move with the wind. It can even breed new dunes. Some of these offspring may be carried on the back of the mother dune. Others are born and race downwind, outpacing their parents. [Source: Farouk El-Baz, National Geographic, February 1982]
      The shape of dunes is affected by things like the strength, direction and consistency of the winds; the consistency and amount of sand; the hardness of the terrain and the amount of vegetation. 
       

      Below we will describe the most common dunes found in the UAE.
       
      Different Dunes
      Crescent or Barchan Dune

      This is the most common dune. It forms the shape of a crescent moon when the wind blows from one direction.
      We generally use the words concave and convex to describe both sides of the dune:
      * Concave is a shape that curves inwards.
      * Convex is a shape that curves outwards.
      Crescent-shaped mounds generally are wider than long. On the concave side you will have the slipface. These dunes form under winds that blow from one direction, and they also are known as barchans. 

       
      Parabolic Dune

      A parabolic dune is similar in shape to a barchan, but it is just the opposite. The tips of this dune point into the wind, and its main body migrates with the wind, forming a depression between the tips. Because of this formation, parabolic dunes are also known as blowout dunes. These dunes often occur when vegetation stabilizes sediments and a U-shaped blowout forms between clumps of plants.
      Example of Parabolic dunes near Faya:

      Longitudinal or "Seif" Dunes

      They are also often referred to to as "sand ridges" or "seifs". Their length can range from a few meters to many kilometers and their height from a couple meters high to a couple hundred meters high. Wind pushes the sand and forms ridges parallel to the prevailing wind direction with slip faces either side of the crest. Linear dunes are straight or slightly sinuous sand ridges typically much longer than they are wide. They may be more than 160 kilometers long. Linear dunes may occur as isolated ridges, but they generally form sets of parallel ridges separated by miles of sand, gravel, or rocky interdune corridors. Some linear dunes merge to form Y-shaped compound dunes. Many form in bidirectional wind regimes. The long axes of these dunes extend in the resultant direction of sand movement. 
      Example in Al Qudra area:
      https://goo.gl/maps/RXHFzR3GW6iFr16C7
       
      Barchanoid Dunes

      These ridges are similar to Barchan dunes. They are connected in long crescentic waves as the sand supply is much greater than that which forms a Barchan Dune.
       
      Star Dunes
       

      These dunes are formed when there are several prevailing wind directions - there is a complex wind regime. Typically there are three or more slip faces, whilst the dunes do not migrate they grow in height.
      Star dunes are radially-symmetrical, spyramidal sand mounds with slipfaces on three or more arms that radiate from the high center of the mound. They are created when the winds blow equally from every direction, causing the sand dune to grow many extensions and resemble a star. They are rare and are fairly stable and remain in the same place. Some are landmarks with names.
      Example of a Star dune:

      With this knowledge, the next time you step into the desert, you can start looking at the different dune formations, and this will give you lots of knowledge that you'll be able to apply in the future when leading and navigating off-road drives.
