    Dynaflex came on the truck I'm driving, 946,000 miles and they still clean up looking good. I don't have any experience with other brands. Screenshot_20260103-045423.png

    Nice rig! Also 950k miles on the pipes is insane! I have heard dynaflex is good. But dang 950k is incredible. I actually found a way to build my own 5" straight stacks out of t406 stainless. I might polish them when they arrive not sure. I just want them to last as long as possible. Not super worried about looks. My truck is typically dirty from off-road and farm deliveries anyways. Just tired of my rusted worn out exhaust. I assembled all the pieces I need for 5" from the turbo to the top of the stacks. 111" total height from the elbow. Full stainless, t pipe, hangers etc for around $700 bucks delivered. We will see how it goes. I will update when I get it built. I pieced it together from multiple places.

    I have dynaflex. About four years and the little rock dings start to rust, but they use so much deicer anymore here it's hard to keep things nice I think I just need to figure on changing them sooner.

    Yeah that is why I specifically wanted some stainless. I hate rust so much. I am alright if they blue or color change a bit from heat. I just don't want them rusting out. I don't keep my truck polished up anyways.

    Hey fellas lots of people probably know this but I was doing some reading. 409 isn't good for anything visible it will get a layer of rust on it after awhile. So I changed my order. Everything under the truck is 409 chrome plated. Stacks are 304 stainless. I haven't messed with stainless much so didn't realize there was such a huge difference in corrosion protection. Hope that helps someone in the future if they read this.
