I just wanted to let you guys know that City Muffler took care of me. John had the answers I needed and when he didn't, he found out and called me back. I needed stuff for an F550 PSD(it's not mine, honest!!) plus I got me a new fp guage and an EZ for mine while I was at it. He will give great prices over the phone also. Everything was delivered when he said. All in all, a good shopping experience.
