Am i the only one on here with flowmasters? I gots the original 40 series and they sound VERY nice
. At idle the just rumble very noticebly. And when you want to open up the duratec, well lets just say theres a major improvement in sound. Performance wise i dont think theres any gain. I have just removed my res and put on two flows. Sounds great. Thats my opinion anyways. Hope your mufflers work out, which ever ones u decide on.
