WILL I LOSE TORQUE WITH A DECAT

[VR IN HEAVEN 0]

Hi all I had a decat on my p reg VR6 obd2. when I fitted the pipe it felt like I lost torque but he car was really good on the m-way over 60. having looked at other posts on the forum I wanted to know If I will have the same problem if I put one on my new VR 97 model obd2. as Not sure if the problem was with my old car in terms of torque. Any response is much appreciated cos I hear lots of different things. I have even been told to chip the car to get the torque back if its lost. This all leaves me very confused?X2£$ Just want a little extra power with the sweet sound and no problems!

Thanks
