[2017SierraSLT]

I just performed the muffler/exhaust valve delete on my 2017 Sierra SLT with the 5.3 and 6900 miles. I used a 3" straight pipe cut to 33" long, and welded it on myself on my driveway. I left the 3rd cat and resonator alone. The tone is mellow and deeper. It sounds like a V8 now. My valve was very tight and had a hard time opening and closing. There was a slight low speed lag that has now disappeared. No doubt caused by the tight exhaust valve. The overall performance, which was already good, is even better now.

Love it.

 

I do have a Range device also though. Highway drone in V4 is noticeable for sure without the Range but nowhere near as bad as people made it out to be.
