i going to help a friend in stall a 3'' downpipe on his 86 SVO that goes directly to the y pipe with no cat on it.Y pipe is 2.5 w/ flowmasters and 3'' tips.the car already has a SS tubular header. How much hp do u think this would add, will turbo lag be almost eliminated? (20 psi)
update, it took 2 hours to switch downpipe because we had to remove the trans crossmember. it looks awesome and sounds very aggressive. the car revs up twice as fast now and the sound of the turbo is very clear, there is almost no lag, after a few exhaust and oil leaks r fixed the car is headed to the dyno i will keep u posted. base #s r 155hp 200tq:SNSign: :Track:
