Very well built and packaged blow through muffler. Really mild and quiet at idle and a really nice deep crisp high note at top end performance. Very pleased with it.

DEPENDING on your vehicles application (my 2012 5.7 Tundra) I left original cats, Installed an Xpipe and through these on the back. What a difference. Sounds absolutely, no drone for me. And has a very nice see growl all the way through the rpm. I had some longer ones prior somewhere between 8”-10” and still was impressed but slightly quieter. Overall, would definitely buy again!

I am very pleased with this purchase. I have a 2012 Infiniti M37 and decided to do a resonator delete. I also installed Magna flow mufflers in place of the OEM. The result was terrible drone at highway driving. After reading reviews, I decided to give these mini resonators a try. I was skeptical that being so small, how could they make a difference. I also installed an X-pipe and these were mounted right after the x pipe. Wow, what a difference they made. They got rid of that awful drone without effecting the exhaust tone. I am very glad I decided to go with them.

Arrived in 2 days. These will be perfect on my 05 Dodge Magnum RT. Cheaper than the options on summit and jegs. Def a good purchase

Size, coming straight of the headers there is hardly any difference in the size of the headers and mufflers. Less to drag or bend. And the sound is beefy, it may be a little loud

I took my 2015 Q50 and decided to ditch the dual exhaust all together. Ended up with headers, the down/test pipes from Megan, the Y-Pipe from Megan, and then I had to custom build what I have now. It used to be completely straight pipes with no resonators or cats whatsoever, but the high end rasp killed. The sound was epic, performance was incredibly noticeable, but the rasp....my god the rasp. So I found this high flow resonator to keep the straight piped sound and performance and minimized the bulk h buying this one. I’m so glad I did too. The Infiniti Q50 sounds incredible now with this TOTALFLOW! So now, there’s 2.5” piping all the way through and instead of dual exhaust exits from the y-pipe, I have one 2.5” exit that drops off right offer my real axle. She’s a real treat to listen to. Hardly noticeable when cruising, but deafening when you step hard. Highly recommend!
