2005 Jeep Liberty Renegade 3.7L V6. Not so much louder as it is deeper. Without my muffler, my Jeep sounded like a ricer, with this, I’ve had people tell me that they thought I drove a SRT8 or that they thought the muscle car behind me was making that noise.

This muffler is replacing another red, straight-through muffler that I installed on my Durango about 8 years ago. While getting 8 years isn’t horrible for a $30 muffler, the previous unit required bandaging and patching several times and I decided I didn’t want another painted muffler. This one is about 6″ longer than it’s predecessor, so it’s a little quieter but the tone is just great. My Dodge is a hauler/work truck, so it has no carpet and at highway speeds, the old muffler had a drone that was kinda annoying…this is almost pleasing even without a tailpipe and an angled tip. Hopefully it holds up better than the old one.

I had stock mufflers on my 1998 Chevy K1500 4X4. I went to a 2.5 inch pipe and ran dual. The truck has more punch now and smoother acceleration. You can’t go wrong with Magna-Flow. Very good price as well. I’d recommend this product if you want a deep sound out of your 350 ci engine.

Great product as always, this is the 4th one of this kind of mufflers in different cars/trucks and all of them sound great, sporty but not that loud! Love it!

06 Gmc Sierra 2500. Bought two of these for my truck and absolutely love them! They need time to break in, about 1000 miles or so but the sound is exactly what I was looking for. Nice deep tones at idle and has a mean bark when your laying into the gas pedal. Doesn’t “pop” like straight pipes do when you get the rpm’s up above 2500.

Gives my 4.6L V8 a deep and mean growl to it, the price is unbeatable for what you get out of it.

As for preformance and sound its amazing. It is loud which i dont mind. For a 4 banger truck it sounds great. Would get 5 stars but its actually aluminum not stainless steel like ad states. But for the price im not complaining. Gained better mileage aswell. Added a tip and elbow to eliminate the stock turn down after axle. Direct install with some ingenuity.

These muffs sound awesome and give a nice low rumble. They on a exhaust system with LTHs, no cats, and 4 1/2 inch tips. Glorious sound!

I installed this on a 2004 Yamaha Roadstar because it fit the retro look. Great sound for a great price. Equivalent bike muffler is $200 +.

Installed this on a 2015 4runner. Great sound, easy install…until the rattle started. It was difficult to isolate. For months I heard it, then didn’t, then did. Finally, after checking all the connections, heat shield, etc., I determined it was coming from INSIDE the muffler. Warranty is one year (purchased 6/23), but I can’t return for any kind of refund after 90 days?!Update: it took 2 MONTHS for a “customer advocate” to contact me via email. By this time, the rattle was incessant and LOUD. I had already ripped it out and replaced it. Terrible customer service. Dropped to one star. Waste of money.

Just purchased this glass pack magnaflow muffler and the insides isn’t seated properly so it sticks out and will change flow of exhaust note, I could of sent it back but already have other muffler off car so I will set back in place and weld to finish their job.
