Q. Will changing the exhaust system on my new car void my warranty?

A. Every manufacturer is different. To be sure your warranty won't be affected, it is best to check with your dealership. However, as a general rule of thumb, any modifications that do not interfere with oxygen sensors or engine managment systems (i.e.; Cat-Back exhausts) are usaully deemed acceptable.

Q. I'm worried about cabin noise and/or drone. How do you overcome this?

A. We are an Australian company that must adhere to design rules and regulations in Australia. This means that the products we make must do what we say they will do, unlike many cheaper, imported goods. Because we offer a 10 year warranty with our products, we use quality materials during the manufacturing process. This gives our systems a 'solid' build and means that our products are much quieter than others available.

Q. My mate told me any exhaust system will do, they all produce the same results. Why should I choose a Hi-Tech?

A. Our systems are dyno-proven by independant tuners without vested interest in the cars we test. With exhaust systems, like many other products, you get what you pay for. A product may look shiny and be inexpensive and might even sound great when first installed but we question the longevity of such products. We gaurantee that the note you get, when you first install our system to your car, is the same note you will have 10 years down the track. More so, any warranty issues are much easier to sort out when both the manufacturer and the customer speak the same language.

Q. Is the system Street-Legal?

A. All our off-the-shelf products are below the legal noise-limit of 90dB. Across our product range we use raw materials that are recognized as purpose-built for exhaust applications. The Catalytic converters we use, for example, are manufactured in the USA and, in individual testing, passed all the relevant R.T.A. and DECC tests including emissions while still giving marked improvements in performance and gas flow.

Q. Will this system bring my engine warning light on?

A. Cars these days are becoming more and more advanced with computer systems and technologies. These management systems can be very, very sensitive to any changes, ranging from power increasing chips to different tyres. However, at Hi-Tech we put every product through extensive R&D to ensure that the products we sell stay within the parrametres set but the factory computer thus keeping your dashboard free from unwanted warning lights. But, ofcourse, if there are any issues arising from our products, we ensure that we do everything possible to sort out any problems and keep our customers happy.
