Exhaust vs brake-lines
I'm starting to determine the routing for the 2.5" exhaust on my 'Recycle' project.
As I was trying to visualize where things were going to go, I noticed that it's pretty cramped where the pipe has to drop down under the manifold on the pass side. There's enough room for the pipe between the starter & frame but I noticed it's going to wind up fairly close (approx 1") to the rear brake-line. How close is too close??

Re: Exhaust vs brake-lines
I had one that rubbed, I didn't NOTICE any problems but kept a cclose eye on it before I did my engine swap, then I re routed the brake lines and pretty much everything else.

Re: Exhaust vs brake-lines
I'm not worried about any contact as the area of concern is where the exhaust pipe does its 90 deg turn after exiting the center dump of the manifold (roughly 9" from where it's attached to the manifold). The brake-line is secured to the x-member & frame in 3 different places all within 6-10" of this area.
It's the minimal gap between the two. I did some reading on the use of DOT-4 vs 3 fluid but there doesn't seem to be enough benefit as far as increased heat potential.

Re: Exhaust vs brake-lines
In most cases, 1" of air space is plenty. In severe race conditions, you could sleave the line with some firbraid covering, or wrap the line with some cool-tec exhaust wrap. But, for the most part, I don't think its a big concern. You could hold your hand 1" away from a header tube for quite a while, and brake line and fluid is a lot tougher than skin and blood.
