I have a stock 98 GT Automatic. Only mod so far is to remove stock 6/4? cat midpipe and install MAC no cat prochamber. Any idea if there will be a power increase? Facts only please, no guessing Thanks.

you can see anything from 10-15HP increase but you cant get a specific answer on your gains since each car is different form one another. Many factors come into play as the condition of the motor and other stuff
i havent gotten my stg 1's yet still waiting for them i'll more than likely have them by christmas and i didnt have a chance to install my headers thanksgiving weekend. Currently i should be at 250-260WHP i havent dynoed in a while and i lost my other dyno sheets
but i have a friend that has them on with LT's they pull hard after 3000 rpm and they dont give up any low end power it totally a different car he dynoed at 298WHP with similar mods as mine that alone and other people that have them here sold me on gettting them
