looking for a mazda3 catback or a speed3 exhaust for my sedan. its about to boil down to me uying the cheapo tsudo n1 off ebay and changing the resonator / tip

Look at local shops to get a custom exhaust setup....like Exhaust Pros.....probably cheaper than buying a Mazdaspeed or other aftermarket setup...

the two i would love to have are the corksport or the f2 one think i could ge one made cheaper in stainless... mandrel bent?
