Nice quality build on these shorty headers, impressed. Seem to have a little more bottom end throttle response. Only thing I changed was the grade 8 lock washer I felt was too small for the header mounting holes, especially the cut out slip on holes. I didn't feel they were tightening evenly
Easy fix tho.

These headers are a pain in the as to put in, but what you get out of them is amazing. Mid power, and pick. And like 5 mpg more.

My manifolds were ticking this got rid of it and ive gained power from the dyno i also have dioblo sport tuner, upgrade coil packs and plugs, afe cold air intake she sound better too with these shorty headers

I had a broken header bolt so I gave these a shot. They look great, welds looked good. I think some of the edges could have been smoothed some but at this price point they are acceptable. You do have to re-route the dipstick (2017 Ram). Tone changed some, everything seems good.

Very nice product and they sound good
