so i think im just gona buy stock size rims so i dont have to buy new tires, and i can get an exhaust. i want to get the ips gen 2 quad tip, but i called a local shop and they said they could fabricate a 3" catback with magnaflow mufflers for the best flow for around 500$ and then i could bring them the tips on ips for 375$. looks like it would save me about 150$, what do you think, should i just have it fabbed? does anyone have the ips 3" system?

A lot of people just have it fabricated at a shop, if you have the tips why not? Just make sure you have them install it so they can fix any fitment issues.
