Warning
If you have an 84-85 FJ absolutely do not purchase the Black Widow Exhaust downpipes and collector for the FJ 1100 unless you want to modify your fairing. They stay too far away from the engine and interfere with the belly pan. After receiving these and installing them, I found this out. Then I discovered others here have had this problem as well. Black Widow has not redesigned them and the customer service is not very helpful. Delkevic pipes or the 86 and after pipes are a better option.
