The car has a tubi with stock tail pipes and one of them for some odd reason looks slightly off. Is it a simple process to straighten it or do i have to take the rear bumper off ?

Thanks

 

You do not need to remove the bumper. The OEM tips are a slip fit held in place with a 13mm bolt/nut.You can get to the bolt from under the car with an extension on a socket wrench. You might want to spray to bolt and nut with some rust penatrent and let that soak for a bit. Those bolts tend to rust. Loosen bolt and reposition as you like and tighten it back up.

good luck
