🚗 MagnaFlow 4x9 Oval Center/Offset Performance Muffler - Straight-Through Exhaust with Satin Finish (11365) Review

As with many looking to upgrade their car's exhaust system, it was a long decision making process. What sound did I want, would it fit, how was it built, would it hum on the freeway (which I hate), etc. I settled on these after hearing them on YouTube. They have a very low rumble below 3,000 rpm, so they don't get in the way in city traffic or on the freeway. But let the revs go past 3-4,000 rpm and it sounds like a Nascar, very loud. So for me the best of both worlds.

had to be modified a bit to fit my wife's R52 Mini Cooper S. The sound is really pleasant. a deep rumble and it really amplifies the pops and pops when you let off the gas. She loves the sound. There's a bit of a drone in the cabin, especially when it's a convertible. We decided to add a resonator to dampen the sound a bit at high speeds. Sounds MUCH better than the fake Megan exhaust I bought at auction. instead of just being loud, it's now hoarse. At idle, it's not much louder than the stock…

was even a convertible like mine) but my convertible has an annoying low resonant hum (around 100Hz) in the car (above up, windows open. It was bad from 1250-1900 rpm (worst at 1750). At that rpm with no load in cruise control it's noticeable and uncomfortable. Accelerate a little or more and the hum is very annoying and indeed does hurts in my ears I can try the 3" longer version of 11225 to see if it sounds less apart from the hum which is very unacceptable to me, they sound great. Just note…
