Hi looking for some advice not really sure how to use this site as it is my first time. I have s Scooby wrx on 51 plate. I have had a new exhaust fitted from turbo to back box and where the down pipe connects to the turbo when it gets hot it smokes bad. Just wondered if this is normal and will stop or is it some thing the garage has done or not done properly and needs to be taken back thanks for advice

 

Newness keep an eye on it.
