Milltek Sport are putting the new performance exhaust system for the Porsche Boxster S 3.2 through testing and initial results in both performance gains and sound improvement are very encouraging. The stainless steel exhaust system consists of free-flow manifolds + hi-flow sports catalysts, rear silencers (available including or excluding rear catalysts) and twin 90mm (3.5") Special tailpipes.
The system, already developed for the Porsche Cayman S, has shown massive power gains and received an excellent review.
The photo shows the cat-back system without rear catalysts. We'll have some photos of the manifolds / mufflers and catalysts very soon.
