New to the Cobalt Club
I recently traded in my Honda Civic and decided to support the American made automobile.
I love my Cobalt and Chevy has renewed my faith in American cars.
One question, What mods will void my warranty? I want to upgrade my sound system and get bigger rims(16" vs the 15" steelies) but keep the same wheel diameter.
If you want to mod the engine, say exhaust,headers,cai, do they have to be GM parts to keep the warranty?
I look forward to talking and learning from you guys.
