    3DI25R - Car Chemistry Collector Inserts is rated 4.5 out of 5 by 4.
    Rated 5 out of 5 by from Not a muffler but it does what it's supposed to do I used these inserts as part of my dual catback system on a Silverado. I had a drone when running in 6th gear at around 1100 - 1300 rpms, which I wanted to get rid of. I did have to use a pipe expander to slightly enlarge the tailpipe but cannot say if the dimensions are wrong for the inserts or the tailpipe as both the inserts were identical. No bid deal. Once installed, the drone was gone. These 3 disk inserts have now made my system volume wise, the same as stock. Not the inserts' fault! I did what another poster did and cut out one of the 3 discs. I am now about 2 dBs louder than stock which is exactly what I wanted. I did install a grade 8 through bolt to hold these in place.

    Rated 5 out of 5 by from Does what it advertises I purchased these for my FFR Roadster. They were easy to install in the j-pipe between the header collector and the side pipes. They added a little low end torque and made a BIG difference the decibels from the side pipes. Great product and fast shipping.

    Rated 3 out of 5 by from Mild noise reduction Great quality but didn't cut sounds enough for my needs. Ended up doing some serious grinding to fit my pipe application (NA, <200 HP). Ran it without end caps or packing material and got a mild reduction in overall volume and took the edge off the drone. Not nearly enough for daily driving though. Ultimately opted for a Vibrant Ultra Quiet Resonator and having great success with noise/drone reduction and maintaining power.
