Evening all I was just wondering would it be worth getting rid of my sports cat downpipe I bought from scooby world and replace with a de-cat downpipe or not?If so what difference in performance if any am I likely to get?Car is running over 300 bhp at the moment.

 

About 2 bhp, according to Scoobyworld. I have the Ninja sportscat dp and reckon it's a great piece of kit. Would think you'd be better making MOTs easier at that level.
