What Straightflow states

Straightflow says the 4×9 inch oval body gives efficient sound absorption while keeping good exhaust gas flow, and the 14 inch length balances sound reduction and performance. The straight-through design supports smooth gas movement with a deeper, cleaner exhaust tone.

Straightflow says the 409 stainless steel gives resistance to high exhaust temperatures and corrosion, and the muffler has welded construction. It lists it for 2.25 inch exhaust systems, daily driven vehicles, performance street builds, naturally aspirated engines and custom exhaust fabrication, and recommends professional welding installation.
