Cr pipes are very restrictive. Classic Chambered is what I used as well and it really improved performance and sound. I replaced the intake manifold at the same time and have before and after dyno results and picked up 70 -80hp and tq. I was very happy with the change. Mufflers $150, fab work $250, new ceramic coating $400, smile on my face when the sound tickled my insides- Priceless. I wear ear plugs when I drive now.
