Noob question regarding oem perf exhaust

can you tell if a car has the performance exhaust just by looking at it?

is there a difference in exhaust tips, etc? or is the only way to know by the sound?

yes, the tips of the exhaust are sharp and thin.
Stock is more rounded and has a brushed aluminum tip that is removable by twisting off

Before (my old stock exhaust)



After (Performance Exhaust)



You can definitely see the difference.

im my option i think the tips on the PE make it rasp. I think if u were to swap in some thicker walled tips it with a angle cut i think it wouldnt resonate as bad. But im just going by guessing
