Reality is... the exhaust u can buy to last a lifetime.
Most high performance mufflers wind up getting replaced.
If not for functional reasons? Its for appearance reasons.
(Unless your whole car looks like crap 5 years from now? Then it doesn't matter) lol
So I think you will be relatively safe with 3.5 inch clearance if ur cautious n pay attention to the road.
But don't expect to lower your cars n add bigger exhausts or even body kits n they remain unscaved.
The only way that won't happen is if u jus don't drive the car.
By the way.... THE CAR IS GORGEOUS! CONGRATS ON THE EXHAUST. N THANKS FOR THE REVIEW CUZ I BEEN THINKIN DEEP ON THIS EXHAUST. NOW I JUS GOTTA CHECK OUT THE GREDDY N MAKE A FINAL DECISION.
ITS ALWAYS AWESOME TO READ! THESE KINDS OF THREADS. THANKS
