A colleague of mine installed a stainless steel system at his Hondas S2000. He thinks the car is running better… anyway… think it makes sense to replace the original Saab 9-5 Aero exhaust with a stainless steel tube from Hirsch? The car runs with its 250hp very satisfied in the medium and higher speed range, however, could be a little more power there. Do you think such a system could do something? Can this be stated in PS? Thanks
