No one commented on my help question about my muffler hitting the floorboard. Assuming I'm going to change to fix the problem, I want more sound. Why does the smaller Maganaflow get a bad rap for "not enough backpressure"? I thought being blown meant you need to have an easy way out for the exhaust. Considering the small Maganaflow to hopefully-economically fix my ANNOYING clunking under passneger seat but if I go through the motions I want more sound. Please comment - everyone.....

 

On a Turbo application, you want a free flow exhuast... but on a N/A or Supercharged application you need some back pressure to make the torque.
