Review on Flowmaster 843051 50 Delta Muffler 409S - 3.00 Offset 🔊 IN/3.00 Center OUT - Moderate Sound, Black: Optimal Performance with Sleek Aesthetic by Darius Early

I have a Hemi in my Jeep Wrangler JKU. I had Flowmaster Pro series headphones, which sounded great, but the rumble at highway speeds was unbearable. Switched to this series 50 and oh what a difference. I can start my jeep without my neighbor hearing me, and it sounds great under acceleration, but immediately quiets down as it speeds up. The only thing I wanted was for the Flowmaster to still do the version with inlet and outlet staggered on the same side. Update June 2020, description says 16 gauge 409S stainless steel but my tycoon adheres perfectly. Is it really stainless steel?
