T180 Smoking

[JesusJohnson]

I have a 2007 RAV4 T180, it has done 80,000 miles and has recently had a stainless steel replacement exhaust and cat fitted by Tony Banks exhausts, it's now started smoking getting progressively worse, mainly on start up and first 10 minutes or so but still get off puffs randomly on long runs, it does not seem to be using any oil or water and no performance is lost and mpg is the same as normal. Smoke seems to be part grey part blue. I do have a video of it that I will try and attach. It was doing the smoke prior to the exhaust being fitted but not as much or often, so not sure if that's the issue or just coincidence.
