John Wags Posted August 21, 2019 Share Posted August 21, 2019 (edited) Can anyone help me decide on a aftermarket muffler for my 03 buick lesabre? I'm looking for something with a deep mellow grumble sound. Nothing to loud but sounds nice at a idle and normal cruising speed. Nothing ricegrinder sounding. I was thinking of going with a magnaflow. Any suggestions will be appreciated. Thanks.

TerryB Posted August 22, 2019 Share Posted August 22, 2019 On a 2003 Buick Lesabre, never would expect that type of exhaust note from one! Magnaflow sure is a logical choice. Link to comment Share on other sites More sharing options...
Marty Roth Posted August 22, 2019 Share Posted August 22, 2019 Years back our 1988 Suburban with a 454 engine and dual exhausts had a pair of HUSH THRUSH, the sound was perfect for the era and the truck - except when we visited NYC and accelerated in the Queens Midtown Tunnel, scared the c*@p out of a cab driver alongside 1 2 Link to comment Share on other sites More sharing options...
60FlatTop Posted August 22, 2019 Share Posted August 22, 2019 Magnaflow referred me to this company: https://www.fulllineexhaust.com/index.php Used to be called 21st Century Exhaust. Just tell them what you want. Really good technical help. Link to comment Share on other sites More sharing options...
