The Flowmaster Force 2's that was installed on my car when I got it are a little to raspy for my taste. I know my 98 tailpipe holders are 99-04 style and I'm curious how those year models exhaust look on our cars. I installed American Thunder Flowmasters (super 40s) on my wifes GT and loved the sound. I have since found out that Flowmaster uses "super 40" on the 99-04 gt/mach1 and "super 44" on the SN Cobras. Is the sound different? Has anyone had experience with both? Really hard to tell on youtube. Pics and advice is appreciated.
