Steven (Texas) | September 30th, 2021
Installation way easier than taking off the stock stuff, look good and perform very well, fit my 16 duramax perfect
Felipe (Idaho) | June 19th, 2021
Bit of a time consuming job to do, but overall happy with results. Saw egts drop roughly 150 to 200 degrees. Also get a bit of a turbo lag on lower end but compensate on top end and egt temperatures
Jacob (Summerville SC) | March 1st, 2020
Very clean, heavy duty and flows extremely well. Everything fit without a struggle. Only issues I had were with the LMM modified coolant tube. The instructions never me ton that the new tube must be installed first, prior to the left up pipe. This is opposite of how it came out. The new design goes behind the up pipe instead of over it. The second issue was also with the coolant tube. The o-ring that came with it was too small and leaked immediately. had to find a thicker one to replace it with. Other than that it's a solid product and well worth the price.
The 3" down pipe fits like a glove with these as well
