Worked great for my application

I used one auger directly in front of the muffler. (Flow master FX) On a 2011 Silverado 6.0 LS. Before installed it was very loud and obnoxious. After installing it has a rumble but it is much quieter than expected. I can't believe the difference. Definitely would recommend.

They work, but my 3.5" did not fit as good as my 3"

I have a set of these in 3" on a street vehicle love them, it really cuts down the rasp and the noise. 5 stars on those. However I bought a set of 3.5" and there loose in my pipe. The 3" I hammered in and good tight fit, the 3.5" theres a even gap going across outside.

I used one of these insert on my 3.5" exhaust. Amazingly quiet to the point where it's almost as quiet as OEM.

Tone down exhaust noise to an acceptable level and leave some thump, also adding some needed back pressure

I used a total of 8 spirals in each side pipe, on a hot rod project, 400 hp engine. Definitely helped quiet it down, probably not quite enough, with no noticeable power loss.

Would Recommend

Exceptional value for a product that works exceedingly well.

Hammer the baffles in place in less than 10 minutes. I would've said 5, but I had to taper grind one of the baffles to fit a little easier. Even so, great product!

Better than expected baffling on LakeStyle headers!
