Hi Guys, I currently have an AU falcon with a 2.5 inch exhaust system and a single muffler. What I am wanting to know is if I upgrade to a 3 or 3.5" system with a single hot dog, will it be too loud?

The car has a turbo and atm the piping from the turbo to the cat is 3" however the exhaust is only 2.5 so might be restricting it a bit. Does anyone know how much the bigger exhaust run for? I paid $198 for my 2.5 about 2 years ago (red back)

Can this be deleted? I put it in the wrong section
