Flowmaster 389-818199 Features:
Flowmaster's® American Thunder Cat-back true dual exhaust system for the 2025 RAM 1500 with the 3.0-liter Standard and High Output engines gives you a great way to customize your RAM 1500 to your personality. This performance exhaust system fits both 2/4 Wheel drive models and is manufactured from 409 stainless steel for years of trouble-free service and performance. Features include dual 3.00-inch inlet pipes leading into a custom tuned 409 stainless steel American Thunder series muffler for great sound and maximum performance. This Cat-back system includes Flowmaster’s exclusive Scavenger X-Pipe with our D-Port technology for maximum exhaust pulse velocity and helps to create a deep exhaust tone.

Included in the tailpipe assemblies are tuned resonators that help maintain a comfortable experience in the cab.
