They told me that had too many complaints from engine lights coming on. As they were emissions friendly i asked nicely if they could do me a 100cell as i was going to map out the 02 sensor to keep the engine lights away but was told they no longer buy in the 100cell cats so can no longer supply downpipes with them fitted. That said though, very impressed with my 200cell, pulls like a train, boosts hard and no engine lights. Very fast delivery too. £328 to my door.
i thought the blueflame down pipe and cat was cheaper than that
