Has anyone noticed a off sound, loss of power or just seeming different truck idling and driving after a 4 inch ? I went to a 4 inch mbrp turbo back, the truck seems to be different. Is there some trucks that just don’t like it. Had anybody every day needed a custom tune for this ? I run the edge evo 2 but I’m gonna stop using it because my trans shifts are to hard. I am gonna keep it as a gauge cluster an get tubes from the sct x4

New exhaust on a 6.0 won't cause issues your just likely hearing it now.
The truck runs fine I throw no codes and it’s powerful the turbo bark sounds weird at high rpm’s not like before but it like claps hard to explain. Not the the normal bark. There is also a hiss the turbo had which is different I might be tripping haha. I know it’s a different exhaust and all but it just doesn’t sound like the other 6.0 in the videos 😂
