Product Details

The Ultra Flo Welded line is Dynomax’s performance stainless steel muffler series focused on airflow, durability, and sound control. This model uses an unrestricted internal path and CRF packing to reduce unwanted cabin resonance without eliminating the aggressive exhaust note many enthusiasts want. Dynomax rates the design for very high airflow and horsepower support, making it suitable for modified street cars and performance builds that need a free-flowing muffler with a controlled tone.

Installation Notes

This is a universal muffler, so fitment depends on exhaust routing, pipe alignment, and available space. Confirm 3-inch pipe sizing, inlet offset, and overall length before welding or clamping into place. The reversible design gives flexibility during installation, and the oval body shape may help with underbody clearance in custom exhaust routing.
