1997 993TT EVOMSit, HRE C100 Wheels, Bilstein PSS10s & Cargraphic Exhaust

We don't always modify 993TT's here but when we do... This lovely black on black 1997 example was well taken care of and only had about 40K on it when she came in. We cooked up a nice three course meal for her including the EVOMSit Software, Cargraphic exhaust and Billet EVO Diverter Valves for a nice power boost. The stock suspension was replaced with Bilstein's PSS10 coil over kit and a set of H&R sway bars. For dessert she got a set of light weight HRE Competition Series C100 wheels wrapped in new Michelin Pilot Sport 2 tires.

First order of business is to get the factory ECU out from under the seat. A 91-octane EVOMSit retune was coded for more power, response and of course boost:

Off comes the factory top-mounted intercooler to get access to the engine:

The factory bosch diverter valves are replaced with a better billet piston design sans the rubber diaphragm which splits in the stock part.

The Cargraphic exhaust and its deeper Euro-tone was chosen for some more sound:

Lighter and vs the stock mufflers:
