Got Challenged....... should I be worried?
I doubt he boughtMAC's and hasn't done more to the exhaust.
He probably at least has a lid. If he has a lid and MAC's and a catback then he is making more power. If you are a 2000 or less then he also has the LS6 intake which you don't. If he's a stick and you are an auto with no TC then he will win and vice versa.
Never trust what they say their mods are. Some people consider H/C and N2O just "bolt-ons".
If your both sticks with street tires then it will come down to the driver.
