2002 Impala 3.4L Exhaust upgrade question
We'll at the momment im either getting a new car or going to get some performace out of my 3.4L , so hopfully somone here can help me out. I am looking for the best possibly exhaust upgrade out there. I know that Borla is good but also very expensive, i really want to spend no more then 500 on a good exhaust system that will give me the performance , mpg and also the sound. I went to NAIO and heard a few of the sound clips but really want to know what people are using on here and see of mayb someone has a answer.
