The full turbo-back system adds a large-bore downpipe and hi-flow sports catalyst to the cat-back system. The large-bore downpipe removes the pre-catalyst and the main catalyst is replaced by a hi-flow sports catalyst. Not only does this further reduce backpressure and substantially boost gas flow but also, because it’s located within close proximity to the turbo outlet, it allows the turbo to spool up quicker and earlier in the rev range. The use of a high-quality Platinum-coated stainless steel catalyst means that emissions levels are maintained within legal limits.
With only the Milltek Sport turbo-back exhaust system fitted, power gains of 8 to 12bhp have been recorded but when used in conjunction with a remap; we have seen these gains soar to a massive 15bhp and 20lbs/ft of torque…on top of the remap. Extremely impressive gains from a relatively small engine!
