Why cant i just cut muffler and cats out on exhaust?
Hey guys i'm new to diesels so this might be a dumb question. I bought a custom sct tune and now looking to upgrading exhaust.
Instead of spending money on straight pipe 4"exhaust why can't I just cut off the cats and muffler off my stock exhaust??? I know its only 3.5" but only having a tune I dont see it making a huge difference besides on my wallet as I only pull a 8000lb boat every now and then during the summer???
Will it sound different?
or should i just cut cats off or muffler or both??
