I am currently running a skunk2 mega power exhaust. Sounds great and the price wasn't too bad. Also seemed to fix the 3k rpm rattle that most of us are all aware of
I also don't like having someone else working on my car. I try to do as much as I can on my own. Google,ci,ti, and ht are ur best friend when it comes to fixing on ur car. Turned me from an amateur mechanic to a mid level one
