My Tahoe now gurgles at idle and growls under load like an Escalade/Denali or HD Gas Silverado/Sierra. No more V8 sewing machines! It also "gets used to it" a little better due to the higher flow rate compared to the standard silencer. If you're looking for noise-busting rules, look elsewhere, but if you're looking for stylish, performance-oriented tone with a performance boost to match, look no further than the Dynomax Ultra Flo. Viewed before installation, it made a well-made impressionโฆ
