[DeTomaso] Exhaust

[GW]

More than anything I was hoping I could see some one else's creation. I 
doubt I am the only one to do do this. I just would like to see how it 
may differ from some one else's.

The tires do come in quite a bit during compression but there is enough 
room (with these tires and this set up) to do this. These pipes are not 
actually between the tires and wheel well structure, they are actually 
to the inside of the tire. They have to stay close to the shock mount 
but with the wheel at the top the room is there.

I just have to make sure as the car runs it has enough room for engine 
vibration.
