I plan on installing a single into duel exhaust system. I've searched this forum and I've been through a gazillion Youtube vids. I'm dead set on installing Cherry Bomb Extreme's single into duel out system. The sound is exactly what I want. I found a local custom shop (HCR Racing) to put the system in for $250.00. Thats the muffler, all pipe and chrome tips of my choice. I can't wait to get it done. I have the O.K. from the wife so all I have to do is come up with the cash for the job and equall cash for what ever the Hell she wants. This makes for a very expensive venture for modifications. WELL worth it though. I found that HCR Racing also makes, thats "MAKES" their own CIA syetems. Customized per vehicle and very, very cool looking. I may have found the one stop custom shop for my HEMI F'n RAM!!!
