"I have the Spectre air intake system, and the Airaid throttle body spacer installed on 1999 Silverado 5.3L. I just thought I was getting the full advantage from them, that was until I installed this Muffler. It really opened things up, faster throttle response, and better high RPM performance. It sounds great, nice deep tone, and not so loud you have to worry about getting pulled over. This is a must have for anybody looking to really get the most out of there Engine. Best of all it took only about 1.5Hrs. to install. Weld right up with no extension pipes, on 1999-2002 Chevy Silverados." —Dustin T from Elkins, AR bought a Flowmaster 50 Series Big Block Mufflers for a 1999 Chevy Silverado.
