Great value
Quality is great. The welds look really nice and it's real stainless. Doesn't quiet down the exhaust too much, but for my case it did help get rid of a lot of the rasp and "fart can" noise. Cruising at lower rpms it's probably 15% quieter. When you're on the gas it's still loud but it doesn't drone. I'm going to be buying a second one to add. Fit was perfect on my 3 inch exhaust.

Quieted down my open exhaust on my 4.3L v6 first gen S10 stock 2.5" exhaust
Someone took my trucks Cat Converter so as a temporary fix to quiet down the insane sound of no exhaust, I decided to try this since its exactly the size of the gap between my my muffler and the Y pipe before and after the Cat. Bolted it up with some clamps and it really did an awesome job of quieting down the loudness. Honestly I'm shocked how well it muffled the sound. The fit and finish is very good and fit exactly over my 2.5 stock exhaust. Install took about 10 minutes since half the work was already done for me. I know it flows well since I felt no difference in power in the truck. Overall solid muffler that impressed me. Would not think twice about purchasing again for other projects.

Very much recommend
I wanted more sound from my car without fully going to a straight pipe. I already had a muffler delete and replaced the stock resonator with this one. It didn’t make the car that much louder, but the exhaust note is a lot deeper and sounds cleaner throughout the rev range. Makes my car burble on deceleration and downshift which didn’t happen before. Build quality seemed good and welded on with no issues. I feel like this is a good option compared to vibrant or stainless steel which can be double or triple the price of this resonator. Overall a pretty good value. I had it on more a month have not had any issues. Hopefully it last!

Not Vibrant quality but it’s decent
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.

Reduces drone without completely changing the sound
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!

Loud!
⭐⭐⭐⭐⭐ If you’re looking for loud, this exhaust tip definitely delivers. We put it on our 2026 Kawasaki KRX, and it made a noticeable difference in the sound. Installation was straightforward, and it fit well. Just know this isn’t for someone wanting a subtle exhaust—it’s loud. We love it and would definitely recommend it if that’s the sound you’re after.

Exactly as pictured, great looking quality!
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!

10/10 would recommend
I put this on my turbocharged track miata a year ago. Other than this resonator it's just a straight piped exhaust. It sounds great and definitely quiets the exhaust note a lot. It does seem to be louder than when I first installed it but it's not obnoxious. Comparable to vibrant ultra quiet resonators but easier on the wallet. Will be purchasing again when I have the need for a new exhaust

Looks good.good stuff
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.
