Autotech specialising in performance exhaust fabrication

Autotech have their own in-house exhaust fabricator and custom equipment that enables them to build the highest quality exhaust systems to suit almost any application, from racing, to performance right through to passenger and SU V. We can do a wide variety of fabrications ranging from off the shelf muffler installs to full on twin turbo custom builds. Exhausts range from 2 inch to 5 inch mild steel or 304 grade stainless steel custom fabricated using the highest quality mandrel bends and tube.

These systems are TIG welded for maximum strength and weld finish and flanged together using a large range of flanges from 2 bolt mild steel to 4 bolt stainless steel with a minimum thickness of 10 mm to stop distortion during welding. Mufflers we use range from well known brands to in many cases on custom big bore systems we use custom built mufflers with large amounts of packing to maintain maximum flow with minimum noise.

As a fabricator Autotech prefer to build custom exhausts using mandrel bends welded together as we can maintain closer clearances to allow the big bore systems to be fitted where there is minimum room which is necessary as with a recently completed  BA Falcon GT twin turbo system which is a twin 3.5 inch system into single 4.5 inch pipe over the Differential back into  twin 3.5 inch pipes using custom built mufflers and exiting via quad tips. Catalytic converters vary from 100 cell psi to 400 cell psi in small or large body configurations depending on flow required and fitting space available. When custom exhausts are completed the mild steel systems are coated in a ceramic based paint for longevity and stainless steel systems polished from a satin finish to mirror finish.

We also have a fully equipped machine shop comprising of vertical mill, lathe and CNC plasma cutter so hard to source exhaust and turbo flanges etc can be fabricated, this also allows custom surge tanks, catch cans, brackets and fittings to be manufactured in house. The vertical mill also allows us to mill flat all flanges before coating and fitting to ensure no exhaust leaks. Our fabrication also covers making custom extractors, turbo manifolds,dump pipes and intercooler piping. Twist mount turbo setup for Subaru WRX, single or twin turbo for Ford and Holden are common fabrication jobs for Autotech and being a fabricator that enjoys a challenge our workshop has fitted turbo setups on many vehicles from Toyota Landcruisers to Ford Escorts and all jobs can be completed with custom engine covers to undertrays if the customer so desires.
