E46 325, 330 (1999-2006) Supersprint Resonator
All Supersprint resonators are of the flow through resonated design. This means each unit has no chambers or baffles to reduce velocity. Simply, a straight through in & out design! The internal components are 100% stainless steel with a high heat resistant rock wool sound suppressing material, not found in any other systems. This is the reason we can offer you sound legal performance exhaust systems. Tubing is always mandrel bent for maximum flow. Flanges and hangers are O.E. or better quality for a perfect fit every time. Housings are all manufactured from 1.5mm material that is M.I.G. welded at all seams. The stainless systems are 100% 304 stainless, the mild steel systems are aluminized on the inside and out, then black heat coated for corrosion prevention.
Note: To be used with 022 787 406 or 022 787 407 or 022 787 456 mufflers only.
