How’d you get the whistle? Never had a tuned lml sound like that without an upgraded turbo, even with aftermarket air intakes. Something different with the L5P?
So I did a 4”, egr is still in there but will be removed soon. But my truck is extremely quiet compared to this. Idk what’s going on and why it’s so quiet
So I have a 2020 GMC 3500, and I don't plan on deleting the def system anytime soon. Can you delete the muffler and leave the resonator without causing any issue, just gaining a little sound? Thanks
Unfortunately there’s not much you can do for sound without deleting. Without proper tuning the truck will throw codes pulling anything off and cause issues. It’s well worth the $$ to do a full delete if you plan on keeping the truck.
@@spools6.648 sir I got the big girl to and fixing to do the same and changing every stock piping up pipes manifold the wright way to do egr not blocking it that’s just gonna fail at some point mine will be one of a kind also putting 67 mm turbo as well basically full build
