Strengths:
good sound after driving for 5 miles looks great

Weaknesses:
no sound after 3000 rpms

Summary:
This exhaust sounds really clean and deep at low RPMs. When you accelerate over 3000 rpms you lose sound and my AEM cold air intake sound comes in. I had to get both of my resonators out to make it sound loud. Right when you start your car you can't hear it that well it takes about 5 miles or so for it to get loud
