You're giving an exhaust sytem only, too much credit. 5-12 is about right for a car with no other mods.silvrgt said:maybe with just the catback/xpipe. with headers i should see around 20rwhp.

Id hope with full exhuast he would manage to get more than 12rwhp, that is way too low. id guess 22-25rwhp with all 3.Kilgore Trout said:5-12 horsepower gain
Does that include the headers? Id say without cats that would come out to an even 20/20 gain.Chopper1 said:MMFF did a test of an 03 with a full Bassani exhaust and got 17.3 rwhp and 17.2 fp of torque.(with cats)
