Review on 🔥 VViViD Black Fiberglass Heat Shield Exhaust Wrap Roll - Includes 10 Free Stainless Steel Locking Zip Ties (4"x25ft) by Brian Olson

Flowmaster FlowFX catback exhaust system for my 2020 Ford Ranger Fx4 with this fiberglass from the catalyst/downpipe from the header to the system tip. Itchy dirty work. The result is AMAZING. Even after intensive driving, the hoses feel comfortable. The reason for this work was that the large Flowmaster pipes give the exhaust room to expand and cool, stopping a little in the pipes. This jacket keeps the gas much hotter to the end than smaller standard uninsulated tubing, keeping gases towards the outlet and reducing gas stagnation and back pressure. The interior of the truck stays cooler. It is very good in Tucson, Arizona, where the temperature exceeds 115 degrees in the summer. The interior of the truck is also significantly quieter, since the foil dampens the resonance of the tube walls.
