This is a Wonderful resonator! It does take some time to break in - But once its broken in it sounds amazing. Zero Drone. Only Awesomeness. I haven't even finished the exhaust yet. It currently ends about 18" behind the front seats. Disclaimer: I have a turbocharged inline 4 cylinder engine. I can not attest to the performance on a non-turbocharged engine or an engine with more cylinders etc. I will be adding before and after videos soon. Stay tuned.

For the past 4 years I have chased the drone and raspiness of the exhaust on my Nissan Titan! Originally I had a cat back exhaust from magnaflow, later I added stillen long tube headers and hi flo cats. Once this was done the exhaust was simply racecar like in sound level and drone was off the charts at almost all speeds. So over the past 4 years I have changed my cat back exhaust back to stock which didn't last long before rotting off. Bought a aftermarket replacement only to have it create to much back pressure and had my check engine light coming on continuously. Finally cut off that muffler and going back to my magnaflow cat back solved that problem. But now the wake the neighbors sound level was back. And the DRONE..OMG the drone. Well after some reading and ordered vibrants resonator!! WOW WOW WOW drone was honestly cut by 90% and sound level is perfect. This product performed way beyond my expectations and actually meet my hopes!!!! Best money spent. Just wish I would have found this 4 years ago.

It did quiet my exhaust (350 V8 w full headers and no cat) by 30% imo. Also reduced drone by 50% imo. Good quality built with nice finish. Wouldn't recommend slipping inlet or outlet inside another pipe as resonator pipe walls are thin. Worked great slipping over my 3" outside diameter exhaust.
