You could either replace the mufflers or add cats.

yep a quieter muffler would be the easiest way to quiet it down -- you could try stock mufflers; and with a little luck you could probably get them free since people want to get rid of them when they upgrade

I have a brand new set of Legato axle back mufflers (all SS) that fit '05 - '14 GT's that I'd like to sell. I have them listed on ebay as well. Make me an offer!


Never been installed. Still in the box. Send me an email at [email protected] if you're interested. I'll make you a heck of a deal on them. (BTW, I have the same exact set of axle back mufflers on my 2010 GT. They sound great and are definitely not too loud. And no "drone" at 2000 RPM as some other makes exhibit.
