Gibson aluminized for Nissan SV 2011
Easy install, quiet but deeper tone, extremely well made. Advertises tuned for mid range torque (only smart choice for a truck) which is clearly aimed at the knowledgeable tuner. That, bullydog GT, and K$N filter w homemade cold air intake/ram air has me up from 14mpg to 20mpg. Also butt dyno can feel a clear difference. I would definitely order Gibson for truck again.
