    • They are pretty thin but lightweight.
Style: Stainless Steel Size: 2.5 Inch
You can weld with em nice. Ran my truck with a connector pipe to my cats from the header and they have so far held up. Will see long time review. Will be back to do so. A little thin though but still nice. Headers, this and then cats. And they make nice sound. You can hear the valves through the exhaust anlittle bit and I like that. Makes it sound stock car ish. I would imagine others would find the loudness annoying though. Will be finishing up full true duals here soon with a dual in/out connecting muffler soon. Just have to finish the old girl. 07 silverado lh6 2 month review. They're still holding up with blue demon flux core stainless wire. No gas. I ran some 308 rod on it as well and they weld nice. Must run 43 amps with the rod and run fast. Don't hesitate or you'll blow through. With 308 blue demon flux core wire. I ran it at 19 with 275 wire speed and yah gotta run that fast too. Don't hesitate. Weaving tiny circles as you move quick helps wet the toes better. But you don't need to. This runs better if u run it like a stick welder. Mig with 90/10 argon/co2 prolly woulda been best. But oh well. First time running the wire. Wanted to try it out. It's worked out. However long review. Months later. Exhaust hasn't rusted as I popped it with acetone and welded with proper wire. I need to redo the flex pipes and I may have em too tight in the exhaust and they're breaking apart a bit. Otherwise has held up very well. Still sounds good since I did it almost a year ago. Has the desired rumble. What's nice about this tubing. Is if u need to open up a hole for o2 Porta. Just put a dot on the spit and hold it there with the welder til it pops through. Makes an almost perfect circle and then you can run a step bit to open it to the desired size for bungs and defoulers. Quite nice. I'm going to be redoing my entire exhaust here soon as I had alot of blow through but I finally bought the proper gas and solid 308 wire to do it with mig weld tacks when holding in place and then I'm gonna tig it out. Finally got a decent welder instead of the easy flux titanium from harbor freight. Which welds nice but doesn't do everything I need to do. Still good to pull around though. I got the titanium 140 multiprocess and it works good. Not amazing. But can be fine tuned to be adequate. I'm a professional pipe and tank Welder. I can recommend this tubing and that welder. ... show more

Great affordable kit, I had plenty of pipe left over to do a second truck if I wanted. My only problem was I saw some flash rust inside the pipe. But it all welded up great

    • First time custom exhaust
Style: Mild Steel Size: 2.5 Inch
Bout this to fabricate an exhaust for my son’s truck he was building. This worked great. Had enough mandrel bends and straights to complete an exhaust for a 95 F150 extended cab. Will buy again when I do the exhaust on my truck; if I ever get it built.

The package came a little beat up, but the pipes sustained very little dings at all. Nothing I haven’t seen on virtually all pipe I’ve purchased from a variety of sources. A couple taps with a ball peen to straighten a couple edges out and we’re good to go. Fitment is great. This kit makes for an easy custom exhaust. Just mock it up, trim, and weld or clamp it up. Will definitely buy again. Saved hundreds making my own exhaust. I have enough left over to do my truck too. ... show more
