This is not a true 3 inch muffler, It's 2.5 with the inlet and outlet expanded to 3 inch. They were not like this when i purchased them in the past. Must have changed the design, bad move I'll no longer buy this brand.

great budget muffler with performance qualities like Magnaflow. not sure what Daryl got with that goof expanded muffler, mine weren't like that at all with a true 3" core. keeps the 500" big block in my station wagon tolerable as a daily driver

Installed on a '07 Sierra 5.3L with AFM disabled. Very nice rumble at idle. Not what I would call loud. Very civil/respectable volume with casual driving. Does come alive at WOT. Nowhere near say a glasspack. Also experience drone at 1600-2000 RPM. Tolerable though. Welds are all solid and clean. Overall I felt I got a lot more muffler than what I paid. If you're looking at MagnaFlow do yourself a favor and check these out. Made in USA to boot!

A true 3in muffler.Still loud but bearable.Have them on a heads cam ls2 GTO.Had to keep my old Hooked aero chambers to really keep it quiet.The straight through design is what sold me.Hopefully they last a long time.

Loved the sound. Incredibly affordable. I paired up with the Jones 3 inch x-pipe on a 6.0 LS and would get lots of compliments for not being too loud, good low tone rumble and when you're wide open throttle they really wake up. I'm using these in all future builds. 10/10 really satisfied with the quality.
