After some research i decided i wanted to put a flowmaster on my new truck, 03 RCSB w/ 5.3. I wasnt happy with the other exhaust shops that i had taken my other truck to so i decided to go to Midas, thinking that a more reputable place would do a better job. I got one single in dual out Flowmaster 40 and had them dump it after the axle. It is so quiet. I didn't want it terribly loud but you can hardly hear it unless you really get on it. The worst part is Midas did a shitty job IMO, terrible welds and there is a little leak i can hear. The best part, they charged me $325. I got raped, and i'll never take a vehicle to an exhaust shop again, i have a welder i just thought they would do a better job.
