Lightest NPP compatible cat-back
As it says - Looking to see if people have weighed cat-backs and what they have found for weight savings over stock while keeping NPP

I don’t have weights, but the stock NPP muffler felt pretty light when I removed it recently to install a shifter (despite its huge appearance). I doubt there’s much weight savings on the table with aftermarket mufflers.

I don't have specific weights, but its gotta be the Borla 60606 2nd cat delete with cat back and X-pipe clamped to the optional NPP muffler.
Wish I had weighed before and after but you're gonna have to cut the stock weight in half and its a DIY'er cut and clamp dream with great results.

The factory NPP muffler actually does not weight that much for its size. I don't think any other NPP compatible exhaust will save much if any weight.

OP- am I misreading this? You want to keep your stock NPP and match it to a light weight cat back/X-pipe, correct?
If so, the Borla 60606 and a pair of these clamps (Vibrant sleeve clamps- https://www.amazon.com/Vibrant-Perfo.../dp/B009OLRGN0) is the way to go if you can do without the 2nd set of cats.  Lightest weight and best sound with retained adjustability. |

I have 2in headers and catless xpipe already and they're attached to the stock NPP Looking for something lighter than the stock NPP to keep weight in the 1LE down
