dB Performance Exhaust by Corsa Reviews


Reviewed By Andy Z (Munster, IN) Reviewed for a 1999 GMC Sierra —12/25/2014 8:27 PM

Replace the standard exhaust which was very loud. This system looks better, sounds better (quiet at idle and growls on acceleration). Had it installed and they were very impressed with the quality and ease of install.

Beautiful Sound

Reviewed By Rafael M (Melrose Park, IL) Reviewed for a 1999 GMC Sierra —7/3/2012 10:02 PM

Good quality muffler. Loud but not loud enough to get pulled over. Love the sound once I reach 2,000 rpm.

My truck has gone from some meek, muffled 5.3L 99 GMC Sierra to "holy cow can you believe the sound of that thing!" Nice...NICE rumble on cold crank and smooth on idle. Exactly what you want. Inside, the high RPM, low gear tone can get defening for a SHORT time. Under power...hoo boy...nice baby. Cruising speeds, hardly notice it at all and that's what I was looking for. Big bang in town, nice and sweet on the highway. Get this system.
