changing exhaust

A couple of things are going to change when you hop up your exhaust: For one the sound will be louder and if you live or run in a neighborhood that does not like the noise, you might have trouble running it. The second thing is if you're going from a crappy exhaust to a tuned exhaust to the one you've pictured, It's going to change the tune of your engine. You'll have to retune the carb because the engine is going to be able to breathe more. This usually results in a leaner setting but nothing too crazy.
 
my freind has done what you have done with the same car and its slightly louder you will also need to give it a good tune after aswell but the good side you get better preformance
