Complete “turbo back” Manta exhaust system – available in 3″ fully mandrel bent aluminised or stainless steel tubing, with the option of leaving out the diesel catalytic converter (intended for off-road use)


Similar to most modern 4×4 turbo diesels on the market today, the Colorado 7 has a very restrictive factory exhaust system. It doesn't take much to realise there are gains to be had by fitting a performance exhaust system. After careful experimentation, Manta arrived at the conclusion that a 3” exhaust was the best option for the Colorado 7, offering the best power & torque, the fastest turbo spool, and the greatest reduction in exhaust gas temperatures.

After fitting the exhaust to the Colorado 7, Manta saw around a 5 – 10% gain in power and torque, while exhaust gas temperatures dropped dramatically.


Combining your new Manta performance exhaust with a RTS Stage 1 Remap will improve power, torque, driveability and throttle response, helps to reduce fuel consumption and gives you the peace of mind that your engine is running at optimal efficiency! With 10 year warranty on all stainless steel Manta exhaust systems, 2 years warranty on aluminised Manta exhaust systems and up to 3 years, 100,000kms engine warranty for remaps performed on vehicles still under factory warranty, you can rest assured you’re receiving quality products and a quality service.
