FG 5.4 Boss XR8, GT & GT-P Models

Performance Exhaust Systems

For many years, Streetfighter exhausts have been widely regarded as Australia’s premium quality and sounding exhaust system for the Ford V8.

Manufactured with 304 grade stainless steel, tig welded, and optimised SLC technology mufflers and resonators, every component on the Streetfighter exhaust is made of highest quality for strength and long term reliability. As important is the ultimate sound quality from every Streetfighter exhaust made.

We believe that every exhaust should suit a requirement therefore we offer many varying sizes and combinations catering for varying levels of note and performance needs. And of course it must look good. On relevant models, we utilise only the very best twin skin stainless steel 3.5 inch quad tips.*

Nothing comes close!

Streetfighter Cat-back Exhausts

If you are not concerned on ultimate power levels or further upgrades the catalytic-convertor back option is a great entry level exhaust. Streetfighter supply this exhaust to Ford dealers and retail customers looking for a great V8 note a step above the standard exhaust.

The choice here is mild smooth note from a 3.5 inch merging into a twin 3 inch exhaust at the rear.

Streetfighter FPV Header Back Exhausts

If you feel that you want to achieve best power levels at a more affordable cost we suggest the Streetfighter FPV Header Back Exhaust. This will utilise your existing FPV headers and give you great power and note.

In addition to our Streetfighter cat-back system, we also replace the factory cats with high flowing performance metal cats. This is our most popular option, allowing for maximum power levels at reduced boost pressures. 

Once again the choice is a mild smooth note from a 3.5 inch merging into a twin 3 inch exhaust at the rear.*

Streetfighter Full Exhausts

This exhaust replaces your factory headers with a larger more free flowing upgraded ceramic coated header. We suggest this exhaust when chasing maximum power and note or if you are planning future upgrades.

The Streetfighter full 3.5 to twin 3 inch is our biggest system with an amazing supercar note. It is suited for maximum power on standard applications and supports power levels up to 900hp.
