The 80 series is a cross-flow design for applications where the muffler is mounted transversely behind the rear end. Delivering an aggressive muscle car sound both inside and outside the vehicle, this is an excellent replacement for Camaros & Firebirds with transverse mufflers. Constructed of 16 gauge aluminized steel and fully MIG welded for maximum durability.
After installing the Flowmaster 80 series, I was pleased with the sound—definitely has a nice tone. However, it felt heavier than I expected. It worked great after installation, but I was worried about the weight affecting my suspension.

Stopped Working After a Month
I was really excited about this Flowmaster muffler at first. It sounded amazing, but just a month in, it started rattling and then failed completely. I’m disappointed after spending so much on it. Not what I hoped for!

Good Upgrade, Minor Hiccups
I swapped out my old muffler for this Flowmaster and I do like the sound. It’s definitely a step up, but the packaging was a bit damaged when it arrived. Luckily, the muffler itself was fine. Just wish it had clearer instructions for install.

Great Sound, Easy to Install
The Flowmaster 80 series chambered muffler really transformed my truck's sound! It’s deep and aggressive without being too loud. Installation was straightforward, took me just a couple of hours. Totally worth it!
