The Great Pumpkin - '71 Duster
So, the tailpipes fit.
This is the right side, looking forward. It's close to the leaf spring but there is enough clearance. The spring won't compress enough to contact the tube. As shown in a previous post, the old system went above the spring arch to the outside and then back to the bumper.
It's pretty close to the right-forward edge of the gas tank but it clears.
This is looking forward and up at the wheel arch.
In the pic below, the two fingers indicate where the EFI fuel filter/return is going to be mounted and about where it hangs down. (note the mount bracket holes above). The pipes won't be super hot at this point though the proximity to the filter could affect it and the lines coming off it. Guess I didn't plan this very well! Regardless, the main feed line routes through the general area where the exhaust tube arches over the axle no matter what so it will have to get some heat shielding. The fuel lines were in similar proximity to the exhaust before and didn't have any problems.
The fuel filter needs to live in close proximity to the tank to keep the return line short so there's not many other places it can go without making things more complicated than necessary. Not sure yet how I'm going to handle this situation but I'm thinking a mount plate can be made to move it more towards the center away from the exhaust tube. I may not even need to do that though. I'll put the filter in and see what it looks like then decide.
The only thing I can see with the driver's side is that the tubing gets pretty close to the rear brake flex line. The suspension is at full droop right now though so once the car is on the ground the line should bow out further away.
Here's the hangers. Don't fret, they will get straightened out.
This shot illustrates where the rear hanger sits in relation to the axle attempting to see how the turn downs might fit. I'm not sure where the connection to the muffler is yet but presumably it's within the clamp area. The axle will move up higher when it's on the ground providing more room. The turn downs that TTi sells are 10.5" long. With the axle at ride height, the end of the turn down would presumably sit just under it.
To be clear, TTi makes a good product. They really can't account for after market stuff or custom parts being too close to their tubing. I guess there is something to be said for either building your own exhaust or having one custom made by a shop since the whole point of going that route is actually to account for non-standard stuff.
The previous owner of my car did just that by having the 3" exhaust system custom fit and welded front to back by an exhaust shop. I didn't think that there would be any fitment issues by going with TTi and there really aren't but I'm still on the fence about keeping the tailpipes. They still look weird to me but mocking them up made me feel a little better about it.
More to come.
