PORSCHE 928 S4 (5.0L V8 - 320 Hp) '86 -> '92

The classic 1992 Porsche 928 GTS is the most refined, best performing version within the comprehensive 928 model range.

Over the years it has become a highly sought after car; an authentic, iconic model, thanks to the superior performance of the modern design, 4-valve head, 5.4L V8 engine.

Supersprint still offers a full performance system, made of high grade stainless steel tubing, which guarantees more torque, more power, and a much deeper sound.

Our exhaust is available in several, distinct options and styles; it also fits the '86-'92 Porsche 928 S4 and the '89-'92 Porsche 928 GT, both of which are equipped with the 5.0L V8, 4-valve engine earlier version.
This system is the ultimate remedy to one of the weakest points of the car; the poor flowing, overly quiet, rust-prone std exhaust.

Thanks to the HJS Motorsport, R&L metallic catalytics, and to the oversize tubing, our exhaust guarantees massive gains in performance, starting from the powerband basement, all the way to redline.

Designed to perform and built to last, as usual, the Supersprint performance exhaust is a must-have for all of the 928 serious owners.
