What Straightflow states

Straightflow says the 18 inch length gives a deeper, more refined exhaust tone than shorter mufflers. The round body allows flexible fitting in narrow underbody spaces. The straight-through perforated core keeps backpressure low and supports exhaust flow.

Straightflow says the 409 stainless steel gives resistance to heat, moisture and corrosion, and the muffler is fully welded. It lists it for 76mm (3 inch) exhaust systems, performance street vehicles and custom exhaust fabrication, and recommends professional welding installation.
