I had a set of summit turbo mufflers on my duster. They sounded good but were just to tame.....didn't have any "grumble" to them and barely showed off my cam. I decided to ditch them for something else and started looking into flow master 40's and decided that's what I wanted. Then learned the thrush weldeds were actually the original makes of the 40 series design and it was basically the same. So I went to advanceautoparts.com and put a set of the mufflers in my shopping cart ....then used a discount code ( easy to find if you go to retailmenot.com and then type in advanceautoparts ). And I think I ended up paying $32.00 for the pair of them TOTAL. And used the instant pick up at store delivery option......then I got off the computer, hopped into my truck,drove to my local advance auto parts store and picked them up. Very simple,saves a bunch of cash AND....they sound awesome!. Very pleased with them and have got a lot of compliments on the sound. Aggressive and deep yet mellow enough for the street.
