SIZE DOES MATTER

At least it does when you are talking exhausts

Upgrading your vehicle’s exhaust to an aftermarket system has always been one of the easiest modifications you can do to a 4WD.
Sinister Offroad says that historically, by bolting on a turbo back exhaust, you could instantly have more power and torque and better throttle response.
However, Sinister Offroad explains that since 2016, all new diesel vehicles sold in Australia have Diesel Particulate Filters (DPFs) installed in the exhaust system as part of the emissions system and so bolting on a turbo back exhaust is no longer an option.
It says while a DPF does a good job at trapping soot particles which is great for the environment, it also kills any exhaust note.
As you can’t legally remove a DPF, Sinister Offroad says that when installing a DPF Back Exhaust, bigger is better.
The team at Sinister Offroad has recently released a range of aftermarket exhausts, aptly named Sinister Exhausts, which includes a comprehensive list of three-inch systems for older 4WDs, as well as 3.5-inch systems designed specifically for DPF equipped 4WDs.
“You might be thinking a 3.5-inch exhaust is overkill for a four-cylinder diesel engine and you’d be right if it wasn’t for the DPF,” Sinister Offroad Chief Executive Officer, Jeff Jones, said.
“By going 3.5-inch straight off the back of the DPF, we are attempting to amplify the exhaust note.
“Most vehicles have also shown some minor performance gains, as well as drops in Exhaust Gas Temperatures (EGTs) which is great for towing.
“Not content with only 3.5-inch systems for the V8 Landcruisers, four-inch Sinister Exhausts are in the pipeline.”
Sinister Exhausts are designed and manufactured in Australia from 409 grade stainless steel and are “built tuff for harsh Aussie conditions.”
