Review on 🚗 Flowmaster 942452 2.25In/Out 50 Series Df Muffler - High-performance Sound and Enhanced Exhaust Flow by Mike Calderon

Sounds fantastic on my 2000 Jeep Cherokee 4.0. Having also tried Thursh Welded and Dynomax Super Turbo, the sound is somewhere in between. You can tell it's out of stock, but it's not overly loud. It hums a little at 2200-2400 rpm and nowhere else. Quiet at cruising speed on the freeway, yet pleasant and audible under quick acceleration. That's exactly the sound I wanted. Revain also sells a 50 series heat shield which should be a good replacement for the factory one.
