is focussport exhaust stainless steel? i was reading somethin on it and it mention stainless steel and aluminized steel?

FocusSport performance exhaust systems are designed and manufactured with the performance enthusiast in mind. We use 2.25" diameter mandrel bent aluminized steel tubing in our designs to ensure maximum flow and horsepower. All systems come with a resonator and our exclusive stainless steel muffler, which features a straight-through design. We now use a new stainless steel muffler consisting of a stainless steel one piece inlet / perforated core / outlet for smooth unrestricted flow, lap jointed all weld construction, stainless steel mesh packing and high temperature acoustical absorbing material. Our systems end in a polished 3.5" angle cut T304 stainless steel tip. Also included are the necessary clamps, hardware for an easy installation.

if you're worried about salt, just wash the underside every once in a while.

i dont have FS exhaust but i do have aluminized steel and have had it for 4 years and havent had a problem here in MA. and they salt the roads if it is going to rain, lol

still, if ur concerned, just get a SS one, then you will set ur mind at ease
