What could I expect from the

Stone Moutain Racing Header/Y-pipe combo
CAI
2.5 catback

on a 95 auto?

My stock was 135 hp and 145 torque but I had to fix some codes and did a tune up after that. Fuel filter, oil change, and O2 sensors.

I want like 170-180 whp, and like 190-200 lbs of torque. Can it be done?

 

Get a JWT or TS ECU. But as is now, Id bet ~175hp and ~185 ft lbs on a perfectly good running car. If you didn't change your knock sensor, don't expect those gains.

 

When I had that setup it pulled 165WHP/172TQ. With ECU I'd say you might be in the 180WHP club.

 

well i foudn my dyno it was actually 145 whp and 160 lbs of torque. I replaced the knock sensor, 2 02 sensors, and fuel filter and I am about to put some new plugs in. I really don't feel the gains from the y-pipe.
