guys,
just wanted to know some thing about exhausts.
1.why do some cars have exhausts on the LHS while some on the RHS.
2.while cars have their exhausts pointed downwards why do bikes have them pointed upwards.

vaastu?? lol..

k my guess on RH or LH is, exhausts are designed so that it blows away from the side of the street away from pedestrians.. so in a LT hand drive country (where the vehicle is originally designed) chances of exhaust on to the RT..

up and down.. not really in certain cars basically the bend is to avoid the vacum formed at the rear end at high speeds from burning up the bumper and plastics.. earleir corsas had this prob if i remember correct..

bikes its more to do with aerodynamics and aesthetics..

Even in some bikes if you've noticed, the xhaust pipe might be pointing upwards, but the xhaust outlet is usually curved to make it straight.

As far as cars are concerned, i don't think it really makes a difference, it's just a matter of where the company wants it. The Vtec has it's xhaust on the rhs but if you look under the car, the xhaust pipe coming from the engine to the rear wheel, is in the middle.

most of the cars have the pipes running in the middle so that they can be accomodated under the hump in the chasis (for ground clearance), unless they have 4 wheel tranny.. and only the end piece will be routed to the sides

Well here are the reasons:

1) As for the LHS and the RHS on Cars it is dependent as to where the fuel tank is located as the tailpipe would be on the other side of that for safety reasons so as not to heat up the fuel tank.

2) As for the bikes the angling of the exhaust upwards gives the exhaust pipe more length hence more area to muffle the sound.

Hope that answers ur query
