  • Dam Sounds perfect! I wish my 4.2l Stx could sound like that! Any Advice on what I could do? lol

  • @MrJimbob18 Engine swap

  • How much does the programmer help with performance? i have the exact same truck with magna flow cat back exhaust. I'm getting a k&n, and some headers. Idk which headers to go with either

  • @stinkyfarts445 I had all those mods, and the Gryphon programmer made it feel like a new truck. No doubt.

  • @TucksAndSkis if you knew what I paid for it back in Feb. 05 with only 1,300 miles on it, you'd understand.

  • how mush is it and to install it? and where could i get one if you don't mind

  • how do you get that computer thing?i want one lol

  • @nwrdesign Might not be a bad idea. The setup I was looking at is the Magnaflow 12198 (SI/DO) with mandrel bent SS pipes and 18" Maggie tips. I found a shop in my area that can do the entire job for about $400 out the door. Just hope it is not a little much sound wise. lol I was also considering the Corsa Db system Si/SO which apparently has no drone whatsoever but really good sound....albeit quite a bit quieter than the Maggie option I imagine.

  • @MCP2002 I hear ya (pun intended) I actually worked on my exhaust in steps, which may have cost a little more in the long run, but I was able to achieve the sound I was looking for without risking "overdoing" it from the get-go. The first thing I did was just replace the stock muffler with a Maggie, I let that get broke in and it sounded great, but I wanted a little more and went true dual, replacing the Y with an X pipe and adding a 2nd Maggie. Finally cut out the rear cats. Might be worth try?
