Hindsight's build thread

[Hindsight]

After driving it a lot yesterday and today, unfortunately the exhaust smell is still pretty bad in the cabin. Worse at speed. I believe it is getting swirled up directly from the exhaust tip as opposed to the engine bay because the odor changes nearly immediately when I punch the gas. I think the slip spoiler I have in the back probably worsens the swirling due to the low pressure area I'm sure it creates just behind it, which is above the exhaust.

I think Sealing the cabin isn't going to do anything to help. I think the only two options left are to try a rear diffuser to see if the low pressure area it creates results in the exhaust getting pulled down instead of up, or to do a side exit out the side of the rear bumper like on the blue R. Otherwise I am out of ideas. I need to fix this real quick though because it takes the fun out of driving it.

This is what I'm considering doing for a new exit. If I do this, it will be like the fourth exhaust system I have made
