MuuMuu101's 68 Dart, A Learning Process...
So, I went to the exhaust shop today to install some Magnaflow mufflers. They're 4" longer than the Dynomax and are straight through in design so it should flow a little better. After we got the exhaust installed, I went and drove around the area. Unfortunately, all of the major freeways around here are in limbo due to construction so I didn't get to drive it for very long at 70 mph. Maybe a mile or two. I did drive it quite a bit on the streets.
Off the bat, idle and the overall exhaust tone is quieter. It's not so in your face and aggressive as the Dynomax (good and bad). I also kind of figured this would happen, but the drone is only partially gone. Now, it's only from 1800-2200 RPM and 2000 RPM still sucks. So, from an exhaust point of view, the only thing that I can think of that would help is the installing long tube headers instead of shorties. So, next I'll probably install some sound deadening in the car.
I was smelling some gas toward the rear of the car and found out that the rubber seal on my gas cap is cracked so I need a new one. I was thinking about getting a locking gas cap this time. There's no leaks, so that's good.
