When it comes to upgrades on a car with turbos nothing will improve power gains like a nice set of down pipes. The best way to free up the power is running a cat-less setup, but with today's emissions regulations this tends to get complicated.
There is still much to be gained with a tune on your car and a high flow intake, however the cats always seem to be the most restrictive point often times throwing these cars into limp mode on a stage 2 tune. The Turner high flow catted down pipes allow you to break that barrier giving your car what it needs to stay out of limp mode when running a more aggressive tune but still maintain the catalytic converters for emissions. You may not see matching gains when compared to cat-less down pipes, but this is the perfect compromise to improve your cars tuning and still be compliant.
Manufactured using 304 stainless steel to eliminate corrosion, keeping the down pipes looking great and lasting the way they should. The tubing diameter starts out at 3" after the turbo running into a 4.5" x 4" high flow cat down to a 2.5" connection to the exhaust system.
