I have normally gone and done custom exhausts on my previous cars, but this time I was looking into having a bolt on specifically engineered for the FiST. So I can easily put in on or take it off. So far I have come across this http://www.borla.com/products/fiesta_st_catback_exhaust_touring_part__140525.html and http://www.magnaflow.com/02product/shopexd.asp?zone=all&id=4822 No figures or sound clips up yet, but I just wanted to share. I'm not pulling the trigger on anything yet. Sorry if I double posted...the desktop site wasn't working so I tried again through tapatalk.
