hi there guys, this saturday im due to get a catback resonated twinpipe exhaust for my 08 plate ibiza fr tdi, my ibiza has been remapped to 180 bhp, nd 290 ftlbs of torque. I wanted an exhaust that wud give me good sound, and maybe a bit of increase in power. One of my family friends gave his opinion saying he thought it was a waste of money at 400 pounds fitted and i'll probs lose power and low end torque. As you can understand guys, i dnt wana layout this cash for a loss, has anyone put a millteck on there remapped fr tdi's? Whats peoples thoughts on power loss, gain? Any advice would be much appreciated guys, i'd like to see a little gain but will my remap settings not adjust to the millteck exhaust or any other probs, cheers
