Hi I have a 2000 blazer and im looking to get a new exhaust installed on it tomorrow im interested in making it sound louder as well as the minor performance benefits. I have no tools so I will be doing this through a shop and I have no clue what I should say, ask, buy, etc. what type of prices should I be paying all together I just want this to be simple and go quickly I know it would be cheaper to do it myself but thats not an option so if anyone could help me answer my questions that would be great
