Default Tried and true mods.. please post!

Just closing the deal on a 97 Olds LSS. Supercharged

I want to know what mods out there WILL fit our cars. And are worth the time and effort.

Can anyone advise?

Enough you will feel it, the police will have your plates memorized and the tire place will give you a bulk discount

I was wondering if we could even run the headers without any fittament issues (oldsmobile LSS guys).
Are you guys buying from ZZP or 3800 performance?

Headers should fit fine. Do you happen to know the body style? W body will fit no problem, H body the trans dip stick will be in the way and a W body dip stick will be needed. Any engine mod that will fit the Bonneville will work on your car.
