What Straightflow states

Straightflow says 409 stainless steel is widely used for exhaust parts because it resists heat, corrosion and thermal cycling. It notes the material can develop surface discoloration or a patina from heat over time, which is normal and does not affect its strength.

Straightflow says the flanged joint can be undone for maintenance, changes or part replacement, unlike a fully welded joint, and that with a gasket and correctly torqued bolts it gives a tight, leak-free seal. It lists it for custom exhaust builds, mid-pipe and rear-section joints, exhaust repairs, performance upgrades and motorsport. It recommends professional TIG or MIG welding, and states the part is for universal fabrication use and is not a direct OEM replacement.
