I agree with replacing the downpipe. Early year viggens only had one catalytic converter (cat) in the downpipe. My '01 viggen stock downpipe has one cat just below the turbo, and a second one below the firewall. Replacing the stock downpipe with an aftermarket unit that only has one cat would add 20hp. THe reason I say that is I have stage 3 SQR ecu but haven't replaced stock downpipe. THe torque is much higher than stock (329 ft-lb) in lower rpm's but stock downpipe causes torque curve to drop like a rock in higher rpm. The resulting hp number is 20hp less than similar cars with stage 3 ecu + downpipe. If I keep the car the downpipe is the next thing on the list.
