    a4 diesel cabroilet exhaust pipes

    Why don't the tailpipes on the diesel cab stick straight out of the back like on the petrol versions?

    Because petrol drivers need all they help they can get to look stylish. Diesel drivers don't need to shout about the power they have.

    Another problem is that the way the air swirls under the car and back up over teh rear bumper, on diesel fumes if they don't point down the fumes roll back over the roof of the car, if you have the windows open then you can smell the diesel at certain speeds, and on a cab it would be worse.

    I only found this out whilst watching somthing on tv, they had it in a wind tunnel to show you how it happens. Don't know if it applies to all vehicles or just some.

    cos diesel stinks, and blows out black smoke so the pipes point down. Also helps to mute the clatter made by the tractor engine. All torque no action

    It's only a couple of quid for a tube which will last you years and years.
    I've never let mine get really bad but with normal use then yep they look like new.

    Think the reason the pipes are faced down is the soot/carbon deposits will stick to the bumper and mark your bumper and for cosmetic reasons as well!

    You could buy a Miltek exhaust if you have the V6 quattro, and then you would need to change the rear trim on the back to accomodate them.

    Or you could cut it just before the pipe curves down and stick on an exhaust trim [img]/ubbthreads/images/graemlins/smile.gif[/img]
