LCGP 3" Inlet Universal Resonator, 3" Outlet 12" Overall Length Stainless Steel Performance Muffler, Polished, Straight Through Design, Deep Tone

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.

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!

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!

Ehhh it’s decent. For the price it’s solid but you’ll still get a good bit of drone. Did a 3in setup after the downpipe on my GS300 using this and a 1320 muffler. Sounds good but drones a good bit when on highway.

Very pleased with the quality and finish on this 2.5 inch by 19 inch overall length resonator. The polished stainless has nice looking welds and is a clean straight through and perforated design exactly as pictured. Many years ago I tried to order something similar which was not where near this level of value and quality. Only time will tell if the fibrous silencing/packing material will last, but I am optimistic based on the look of this. Will be ordering three more for my s500 with the M113 engine as I build an exhaust from the long tube headers to some turn down tailpipes. With other mods, the conservative guess more than 20 percent more power to the rear wheels. Those mods being: Used camshafts from a C209 chassis, where the 5.5l m113 made 367hp Porting the heads, to clean up casting imperfections and reduce the guide bosses, and back cut to the intake valves Flipping the intake to include phenolic spacers where it bolts to the heads, and adding some heat barrier material in the valley underneath as well as cleaning up the castings inside and cutting the throttle body opening to match the s600 80mm unit, this means also using an m113k thermostat housing, and cutting away the SAI air pump bracket from the timing cover, after SAI and EGR delete (for off road use) Cold air intake in the front of the engine, so not heat soaked by the valve covers like OEM The long tube headers and exhaust are likely the biggest gain, with cams and head and intake improvements coming in closely behind but we'll matched. The 722.6 automatic 5 speed will be controlled by the Ultimate NAG52 module made by Ash Combined with the new rear differential going from 2.82 gears to a lower ratio of 3.46 with a quaiffe torrent style diff. Gearing change of 22 percent more wheel torque, and hopefully close to that much again increased engine output. Looking at a Chrysler Nag1 torque convertor, with a higher stall speed and upgraded lockup clutch as well as being a "hard hit" style. Taking two full seconds off the 0 to 60 time would be great, from like 6.2 to 4.2 seconds, and a quarter mile et of 12.5 seconds (on slicks) from the original of 14.7 seconds. Those are the thoughts, hope this helps someone!

Sounds great. Would use again. Not a ton of db loss, which is the point. Lol. They are actually very good quality. Welds are cosmetic tig over stainless mig, which is to be expected. Thicker gauge than needa to be. 10/10, would buy again.

Used on a 2010 Challenger. Gave her more rasp and enhanced her deep growl.

Installed on cummins 12v straight 4 inch exhaust. Better sound and muffled just enough. Idle much smoother too. Would buy again

Surprisingly did a really good job on helping with rasp but didn’t take it all away since it’s very small, and didn’t reduce noise at all which to some might be a + or not but for the price is really good
