Hey all. I have a 78 c-10 with a carbed 5.3 and custom built long tubes. Right now it has duals with 2.5" flow super 44s. I have never been a big fan of the flowmaster sound, so i'm thinking of changing up my exhaust. I was thinkin of dual 3' with x pipe and dynomax bullets with pipes all the way out the back. I just wanted some input from you guys. Maybe some other suggestions for mufflers, x-pipe or not, and tube size. Any input is appreciated. Thanks
