ive got a full remus syste with sports cat and a 4-2-1 mani. is alot more responsive.... bhp gains i havent tested it yet but before i ran the car on rollers completely standard (with crappy oil, filter, centre box) and got 142 at the fly. 116 at the wheels. which for a 14 year old car (at its worst soto speak) i thought was pretty good
not sure when im going on the dyno again but wil let you know the results when i do!
