Axleback or Catback
Looking at the different exhaust setups for my Shelby. What would be more beneficial in getting since I already have the factory X pipe? Looking at either Bassani or Magnaflow axle backs or the Roush cat back exhaust? Will be adding the JLT Big Air intake with tune, 127mm Ford racing TB and possibly a 2.6" SC pulley down the road. I really want a little more rumble over the stock setup I have now. Thoughts?
