on Monday June 10, 2013 I got my car back from the Mechanic. I had a d16z6 si engine swapped with dc sports headers, AEM adjustable cam gear, sceptre (pepboys or auto zone) intake. I have a 95 4 door w/ 2 in piping catco cat, Hush power resonator, Megan racing dual exhaust. I recently took off the spoiler.
