  • Good choice if you want to keep your car loud, but more refined, deep and burbly.
Color: Black Size: 2.5" Inlet 11.5" Overall Length
I bought the 11.5 inch overal length one. My Hummer H2 has equal length exhaust with an x-pipe and x shaped muffler dual in dual out to dual tips. Put these 2 resonators instead where the cats were. Car was still loud but it sounded nicer. No rasp but more burbles on WOT. So if you are scared you will lose the loudness, trust me don't be. Didn't really notice any significant drone or loud humming/vibrations. If you want a quieter exhaust, buy the bigger resonators from LCGP. ... show more

  • Reduces drone without completely changing the sound
Color: Silver Size: 2.25" Inlet 13.8" Overall Length
I am very sensitive to exhaust drone but I still always modify the exhaust on my cars so I have spent a lot of time testing out various resonators over the years to see what nets the best sound to drone ratio. Most if not all aftermarket exhausts have some drone even if the manufacturer claims they don't. Up until I tried this LCGP, my go to resonator was the vibrant ultra quiet. It is great and very effective at reducing drone but it's at the cost of a significant reduction in overall exhaust volume and it significantly changes the tone and note. It's also very expensive. I finally gave this one a try because at a third of the price I figured it was worth a shot. And I am truly impressed. They are the same overall length so I was able to swap the two in and out for testing and in my opinion the LCGP nets a better sound by a long shot. Believe me it surprised the heck out of me too. Here's my thoughts: Pros: -Does just as good of a job at knocking down drone as the Vibrant (although not all of it, see my cons) -Very minimal change in exhaust note. Slightly deeper and less raspy but still very similar to before -approximately a 15-20% overall volume reduction. Vibrant ultra quiet is probably closer to 30-40%. -Much more affordable than the Vibrant -small form factor and fits in tight spaces -Many different sizes & lengths available Cons: -Welds and general build quality are not as nice as the Vibrant but still plenty good enough to be under the bottom of a car lol -Does not completely reduce the drone. Approximately a 50% reduction. About the same as the vibrant Here's the deal: I've spent enough time modifying exhausts in my life that I know a "droney" exhaust will always be "droney." There's no magic tool or component that will get rid of it completely. Even J pipes can only reduce drone in a very specific RPM range and not throughout the entire range. So if you want a completely drone free exhaust, don't modify the stock exhaust at all. All those giant mufflers and resonators are there for a reason. In my opinion, a realistic goal for an aftermarket exhaust is to reduce as much drone as you can so that its tolerable, without sacrificing the sound and tone that you want. From here on out I'll be using this rather than the Vibrant simply because it does just as good a job at reducing drone while still keeping close to the same overall volume and tone. It's also about 1/3 the price so to me it's a win win! I gave it 4 stars instead of 5 because others out there have a better build quality but it's still good enough. Hope this helps! ... show more

  • Resonators installed on LS3 restomod Corvette
Color: silver Size: 2.5" Inlet 11.5" Long-2 Pack
This solved the problem I had with an LS3 C2 Corvette exhaust. I installed two Black Widow Venom mufflers and it was just too aggressive sounding especially between 1500 and 2500 rpms. It had a Resonance that would really rack off between those rpms. I installed two of these Resonators and it completely took away the objectionable sounds without reducing the overall sound. It’s just what I was looking for. The Resonators are installed before the mufflers. They are beautifully made with very nice TIG welds and polished nicely. Highly recommend! ... show more

  • Excellent value!
Color: silver Size: 3" Inlet 16" Overall Length
I installed these on my old hot rod. The Delta 40 Flowmaster mufflers have an awesome sound but at cruising speed the raspy drone can get a bit annoying. After installation of these resonators I was pleasantly surprised at the noise reduction. While it doesn’t make the exhaust quiet by any means, it does take away the harshness when you’re up to speed. I estimate about 25-30% reduction in the raspy drone. It actually made the exhaust sound better in my opinion and allows you to hear all the glorious sound that only comes from a 90 degree V-8. These resonators are extremely well constructed of stainless steel and have a straight through design with no reduction of diameter which still allows the free flow of the pipe. These happen to be 3” diameter but I’m sure smaller pipes would reduce the noise a bit more. They slipped right in after cutting out a corresponding section of pipe and attach easily with band clamps for a crush free and leak free seal also allowing for easy removal if needed. Definitely good bang for the buck! ... show more

  • Nice product for the money
Color: Silver Size: 2.5" Inlet 16" Overall Length
They are awesome, now the car sounds as mean as it looks. You can drive normally and it’s not too loud, until you get into it. Normal driving they have a nice aggressive tone. Don’t let the price fool you they’re as nice if not better than more expensive ones

  • BEST PRODUCT
Color: silver Size: 2.5" Inlet 11.5" Overall Length
This has cut the noise down in HALF. Exactly what I was looking for. What I have is 350 Small Block. Speed Engineering Mid Tube Headers. This product. And 2.5 inch straight pipe to the axle. Drone is gone for the most part. RECOMMEND TO EVERYONE
