Noticed a boost in low end torque which is what i wanted, -easy to install, looks NICE but the sound in my OPINION sounds a little bit like a loose fan belt than a whistle. I can live with the sound being as it does not make it(the sound)all the time. Have not noticed a boost in mpg-but then again i don't drive like a granny.. Also have a adtr ported upper plenium, Modified Diablosport tune,and free flowing mufflers so she's running great now!! Yes i would buy again sound and all.
