If the 2.3 I-4 SEL comes with dual exhaust system. I could also put it on the SE version, right? So how come the Magnaflow dual exhaust system is only for a V6 version or is there a version for a I-4, also? I asked my dealer that I would like to add a dual exhaust system for my 2.3 I-4 SE and they told me that I had to buy it from a OMD place. He told me that they don't sell any. Wouldn't you think they would know by now that people that buy a SE I-4 might want to add the dual exhaust system?
