The twin's little brother, is no runt of the litter, you can still expect the quality GSL sound you've come to know with the single exit 4" stainless steel system. One of the hottest systems on the market; twin exit, brushed 304 stainless steel, 4 inch pipe, handmade and tig welded in shop. Which means our exhaust systems are completely Australian Made. TURBO BACK The ‘turbo back’ systems are great for pre DPF and DPF models. They give the true V8 note and best performance gain of all exhaust types. However, recent models are legally required to have a DPF in place. This variant of exhaust removes the DPF entirely (on the DPF models) and in most areas, this is an illegal modification - thereby potentially voiding any warranty on the vehicle. This is an option for off-road and track use only. Please talk to us about getting this option on your vehicle. The system starts with a cast stainless steel 5" dump, moving into a 4" CAT, a 4" muffler section and finishing off with a 4" tail. DPF BACK This system utilises the standard DPF, while still delivering the great note of our exhausts. If you’re chasing sound over performance, then this is the perfect exhaust. From the back it’ll look just as good, so you don’t miss out on aesthetics either! This option is great for everyday use, as it’s a little quieter and keeps your vehicle compliant with vehicle emission standards. The system starts with the factory DPF to 4" adapter section, moving into a 4" CAT, a 4" muffler section, and finishing off with a 4" tail. NOTE: When purchasing, you will need to provide information on if you have any toolboxes, larger fuel tanks & suspension upgrades. Custom made to order, enquire about lead times.
