Ever since I did the L67 swap, there have been two things.

Driving around town with the hood on, it was always the cam (via exhaust sound).

Parked at a cruise in or driving with the hood off, it was always the supercharger (swapped the engine with a fully polished M90, now it has the whipple).

 

No particular mod - the whole car in general. Most compliment on the stylish body, Foose wheels and the overall cleanliness of the car.

 

Mine is the red and black theme. My second would be my headlights because they are so bright. I have 55w hid low beams and 35w in my fogs. They are both 6000k

 

My rims on the 06, people ask me what brand and I tell them stock lol
