Exhaust Question
 

I purchased a MazdaSpeed exhaust. My question is if I wanted to do custom exhaust work...get mandrel bent custom exhaust pipes from the cat back using 2.5" piping.....is it possible to retain the MazdaSpeed exhaust? Meaning could it be fitted onto the 2.5" piping? Obviously hacking the old part off that goes over the axle?

Well in that case.......i would go smaller....i'm not running a turbo but am planning on it....i was just wondering if i could use the Mazdaspeed muffler if i went to bigger piping.
