Wow! This is a very high quality product. The craftsmanship is as beautiful as the sound and performance gains. It added very noticable low end torque and a faster spool up. At idle and inside the car is only slightly louder than before. Sounds awesome matched with my stainless saab sport exhaust. It really lets people know you arent driving the average Saab when you want it to . Installation and fit were perfect the first time, just order a new clamp along with it. Considered buying a more inexpensive DP, but I had zero regets once it arrived at my door. Next Stop - NORDIC stage 3.....or 4.
