Exhaust system

[FirstTimer]

Whats up guys? Probably my first post. I've been browsing for about a month. Bought my aveo last month. got an 08 aveo5 ls 5 speed. I have to get around to posting pics. Anyway.. I'm looking to do a full exhaust system replacement. Headers to exhaust tip. But I'm starting to realize this 1.75" pipe seems way too small. Is there anything extra to do other than buying all the new pipes in a 2-2.5"? My worry is from the engine to the manifold?

The size is not that big of a deal on these, you just want to remove the cat's and such. Someone was selling the xaio header on here, I recommend you buy it as you will most likely never come across one again. Quite honestly, I had just changed the muffler on mine when I had mine, the noise was fun for a while but a few years of it will just begin to annoy you. You will gain some upper end power but not much. Welcome to the forum btw!
