Magnaflow Performance Mufflers Reviews


perfect sound and stainless too

Reviewed By William P (Mount Vernon, TX) Reviewed for a 1938 Buick Special —4/12/2018 4:58 PM

Used these on a street rod with 350 sbc 300 HP show car. Sounds good at idle and wakes up when you romp on it. They almost eliminated a drone problem.Just loud enough to let everyone know the car is not a wimp. Would definitely buy again.
