Upower 3 Inch Inlet/Outlet Exhaust Muffler, 3" Inlet Resonator with 18" Length Overall Length 22" Resonator Great Tone Universal Stainless Steel Muffler Resonator

02/18/2020I Installed this today in my 2006 Jetta 2.0tfsi (turbo) I used the band style clamps.I have a magnaflow decatted exhaust and after run in, it became too loud cruising. I had previously purchased a vibrant 18” resonator to use. It quieted the drone a bit but didn’t was not enough.I installed this 3” muffler today just after the rear oxygen sensor, and it made a big difference. The “drone” is gone completely on the highway and is much less noticeable in cab during accel. I only put about 10 miles on it today, will try and report back after a few months of driving.I gave 4 stars because there were no install instructions. I had to call around a few local muffler shops to confirm which direction it was supposed to be installed, which was aggravating, as you can imagine they wanted me to just bring the car in for them to work on.** See my attached picture for reference of direction of flow. **The wall thickness is very thick, good for welding. I didn’t have time for welding today so I just used HD band clamps. I had to slightly “notch” the muffler in 4 spots (cross pattern) on each side. This allowed the clamp to “draw” the metal together. Just overlap the joint a bit, It sealed up good.

I used as a resonator to kill the drone my new exhaust had. Put it before the muffler and the drone is almost completely gone, and the interior sound level dropped a solid 30-40 percent.You cannot beat the price.

2010 f150 crew xlt. I love the tone and sound of this. I got the 3” in/out and used reducers to 2-3/4” and one 18” section of 3” tube. Welded it all up and sounds fantastic. It is stainless and welded with thick wall steel. It will outlast the rest of the system.

This was pleasantly surprising. Excellent quality for the price point. Very well made and the welds are superb. It offers a nice growl and blub bub bub bub blub you look for in a V8. Had a full rich sound not that hollow, tinny rice burner sound you get from some of the more affordable resonators. I hollowed my cat on a 5.4 and it sounded awful. I added this after the cat and before the muffler and it was exactly what she needed. I ran it straight for a bit just to hear it sing and it was very nice. Unfortunate it's on a commercial vehicle often under load so I didn't want to do that to my customers.

I put long tubes on my Ford 7.5L 460 efi, with 3" true duals and 2 borla pro xs turbo mufflers. It sounded good but droned badly in 5th gear on the highway. These resonators completely eliminated that drone. Its now very quiet at highway speeds and a pleasure to drive. Good resonator for the price!!!
