Hello everyone. Alright, please don't get all pissy with this thread if it's already been done. Checked some other ones, but they weren't exactly about what it is that I'm wanting to know. I know, or at least have been told, that some of the differences between the EX and SX Koups are the suspensions and exhausts. So what exactly are the differences then? The SX has a high flow CAT as opposed to what on the EX? Are the pipes also wider? Also, the "sport tuned suspension", what exactly makes it so? Per the parts department at my dealer, the springs and struts on the SX are a different part number than the EX (which is all they could really tell me), so obviously that means they are different, but how so? Are the SX springs more firm? Are the struts as well? I know most people with SX Koups are still getting aftermarket springs and exhausts, so the difference in SX and EX can't be that much more if they're still also being substituted, but if they're still better and I can get them for much cheaper than aftermarket stuff and still make my EX a little bit better, than so be it. Sorry for making this so long. I would appreciate the information. Thanks everyone.
