ok, I'm going to alter my car. What I'm thinking right now for starters is dual exhaust, just cause yeah, I want it. Second, I'll change out my ''system'', which will basically just be custom boxes and amp and all that BS. Lastly for my major projects this year will probably be installing a shaker. My question... will I need to change any parts of the engine, drivetrain, or any thing else so that these mods won't damage my car? I realize this won't add a lot of horsepower or torque or anything to my car, but it's stuff I really want. We're talking about $1,000 for it all. It's mostly cosmetic, but yeah, again, I want it.
