for a while now i've been wanting to put some upgrades on my blazer but i never knew what to do. add in that i dont really know that much about cars and i just wind up sounding like a teenage idiot. i know my way around a car for the most part and i catch on quick but keep that in mind when you start adding technospeak.
anyways to get to the point i was wondering what i should do if i want to increase performance on a high school budget. intake? exhaust?
also i want to put a new muffler or whatever you call it on the back so it sounds loud but deep. not like a ricer. they have those at school and i just laugh at them. you can hear em across the parking lot doin bout 5 mph. hate it.
also truck has 208.5k miles on it.
thanks.

 

Flowmaster cat-back exhaust.
K&N air filter
Hypertech chip..

Thats all I would do to a car with that many miles on it. Expect to spend about 600-1000 bucks on all of that.
