Review: Must have!!! - Used these to replace the resonators on a 2023 challenger gt v6 and pulled the the mufflers. Much louder and throaty ar 40Mph and below on surface streets and if you want them to roar put the pedal where it belongs....to the floor!!! yet atb75 mph on the freeway they are nice and mellow. VERY HAPPY WITH THESE!! Also have a single one on a 2018 wrangler jlu with just 16 inches of pipe coming off it under the seats. Also sounds great!!!
Review: Did it's job, I think? - I bought this resonator to add to my existing setup on my 03 Honda Accord 2.4. I have a 2.25" catback exhaust with a Vibrant 1140 ultraquiet resonator and Vibrant 1040 muffler, which sounded AMAZING in city driving. After driving my car for a long-ish drive on the freeway (mostly around 80mph @ 3k rpm), I felt like I was going deaf due to the droning in the cabin after 30 minutes. I asked Chat GPT on which resonators I could use to tackle my problem and was suggested this Magnaflow resonstor, but still keeping the deep tone that my car has. This resonator definitely toned down my car just by enough, which is perfect, but I still have not tried bringing it to the highway for long periods of time at high speeds.

## Questions & Answers

**Q: Will this fit a 2012 nissan sentra SR?**
A: With custom welding it will fit. But keep in mind this is resonator to cut down on rasp. Do not use as a standard muffler

**Q: On a scale of 1-10 how loud is this?**
A: If 1 is an OEM exhaust on a Prius and 10 is open exhaust on a cam'd big block v8, it's about a 5.  On my 6.1 HEMI, they are probably 2 (on your 1-10 scale) louder than the large, oval style MagnaFlows I had on before, both at idle and pulling out.  The tone is better in my case because I factored in an "H" pipe where there were just 2 separate paths from the headers to tips before.

**Q: Willsl this fit my 08 Toyota tundra**
A: V8,Yes.

**Q: will this have a deep but very loud sound on a 5.6L V8?**
A: It depends on a lot more than just the muffler but generally, yes, this type of muffler cuts higher pitched tones and let's you hear the deep ones. I have also like deeper exhaust sounds and have built about twenty systems with various magnaflow mufflers. If you use just one if these per side it will be very loud.
