Introducing Flowmaster's new FlowFX Cat-back exhaust system for the 2017-19 Dodge Challenger R/T and TA with the 5.7L Hemi V8 engine and Factory Active Exhaust Valves. This system is perfect for the person looking for a moderately aggressive exterior and interior sound level with all of the performance benefits that you would expect from Flowmaster. Features include mandrel bent 3.00-inch stainless steel tubing into the Scavenger X-pipe cross-over for maximum performance and tone, flowing into a pair our new FlowFX "straight-through" mufflers for a deep and powerful sound. The dual 3.00-inch mandrel bent stainless tailpipes retain the Factory Active Exhaust Valves and the system is finished off with aggressive looking quad 3.50-inch black ceramic coated 304s stainless steel tips embossed with the Flowmaster name, putting everyone on notice that you would rather lead than follow. The large quad tips exit within the rear bumper valance and gives your car the look that it should have come with from the factory. This system is designed to use the factory hanger locations, includes all necessary parts, hardware and detailed instructions for a relatively easy at home installation.

Used it on HVAC ductwork did its job and stuck well
Model: 197mil 31 sqft Car Sound Deadening Mat
There was a lot of material in here for the money, so a decent value, I used it for some extra sound deadening on the ductwork in my house before finishing the basement, seems to help cut down the echoes coming through the ductwork. Overall the product was good had a few pieces where the sticky tore off the foam and stuck to the paper backing but all in all no complaints.

A worthwhile addition to just butyl itself.
Model: 197mil 31 sqft Car Sound Deadening Mat
I used this as a topper to butyl sound deadening material on the floor and side panels and am very pleased. It was generally easy to use. It is very sticky and cannot be easily repositioned as the foam will separate from the sticky side if you try, but its not a big deal. I have yet to run the car but the panels are much quieter when tapped on vs just the butyl alone, and this stuff weighs almost nothing.

Easy to install and great value.
Model: 197mil 31 sqft Car Sound Deadening Mat
Very easy to cut and install with the rollers I bought separately. It adheres well even though I was installing it when the weather was closer to 40-50 degrees. Definitely helps to deaden the sound from the bare sheet metal.
