/SUPER PRO STREET 9000
/Super Pro Street Muffler 9111 2" Center/Center
Excellent sound on a 2.5L engine
"I have a 2016 Mazda 3 GT with a conventional 2.5 L engine (4 cyl., 184 HP; not a turbo). I replaced the factory muffler with a Y-pipe and two of these SuperPro Street 9000 mufflers (2" in, and 2" out) ... The sound is great; it's not too loud and there's no drone. The car now responds much better to the gas pedal and acceleration itself have improved. I'm very happy. My Mazda now sounds and drives like a sports car. Thank you, Spinach!"

"I have the 9000 series on my mustang. Its sounds so awesome, deep throaty and nasty. Forget spending money on a catback or axleback..........just add some of these and use that saved money for more mods!!! I get compliments all the time."
