So, I bought an Ebay special from someone off Facebook and paired it with my catless downpipe and got a tune. I now have an exhaust leak sound coming from under the turbo so I am 90% sure I have a leak in my flex section. (Will know for sure tomorrow when I have some time to get under and really get into it.) So, far I cannot find it with feel alone as it is so tight (and hot) under there. Short story long, I want to see what the community has before I go and order one. LMK, Thanks.
