[QUOTE=powerrodsmike]I've seen it a bunch. For some lowered cars with triangulated 4 bars it is a necessity. You can't fit it over, so you fit it under.

Thanks for the replies guys. My setup is just that:
a lowered car with a triangulated 4 bar.
not a lot of room for going over the top of the axle. I have to mock it all up to see if going under will work.

The other thing you have to worry about aside from suspension travel is the scrub line.
This is a line running from the bottom edge of each wheel to the bottom edge of the opposite tire. Where the lines cross and up is the safe zone, below the lines is the danger/death/damage/destruction zone. There should be NO component of the vehicle in the DDDD zone. If you should have a flat tire anything in the DDDD zone will strike the pavement and either be destoyed OR bring the vehicle to an immediate and very dangerous stop usually spinning out of control.
Do not violate the scrub line.

Under the rear axle exhaust installed

I see that this is a very old discussion but it really helped me out when building my exhaust. Everyone I talked to said to never run the exhaust under the axle. My car is lowered enough to create problems with exhaust running over the axle. It is installed under, and is working out great. I drive this car most days and have not had any problems.

Hay how about the old Ford drive shafts, front was tail pipe size and flared up to a nice cannon size of 2.5 or 3 inches at the other end ....

But my suggestion as folks who know me is always ........SIDE PIPES !~

I thought driveshafts as pipes was just a local thing. We used them when we were teenagers. There was a long steep hill,about half a mile in length. Fifty dollar Fords were still plentyful. With your car in second gear,Those pipes would rap and burble all the way down the hill. Probably get a huge ticket if you did that now.

You got a huge ticket then!!!! (more than one!!!) I got so many tickets with my 50 ford that I had to put glass packs on it......I could not afford the tickets and losing my license and my Mom and older brother lad the law down to me .... put mufflers on it or no car.
And on drive shafts as pipes,most every one used them ,it was a cost thing ......2 bucks at the wrecking yard for drive shaft vs 7 bucks for chrome pipe at the auto parts if I remember right. I made myself some good money back then building exhaust systems out of drive shafts, and building headers for flathead Ford V8's by welding freeze plugs in the tube and packing it full of sand and heating it and bending around a old gas cylinder ........Man those were the days.
