All i can comment on is my experience. I will quite happily show anyone that wants to come and see the poor quality of the exhaust system. Yes they are very friendly and a lot of the work they do is good, BUT the end result i got was not what i paid for. Its still good, as Has will confirm as he recently commented on it, but the workmanship isnt the greatest, the fact they did not fabricate a piece of stainless steel to go over the rear beam and left in the original piece of mild steel just isnt good enough. Still, once i get a new back box that has that piece already fabricated, and get the dacat fitted properly, it'll be ok, but the fact is, I SHOULDNT have to do that. Its already cost me £400, and dont see why I should have to spend more money to get it right, but i do, and thats because energized.
