just had a new engine and now sounds like air is escaping from the cat how much extra bhp does a de cat give you and if i was to do it would i get any problems

Well the VVC engine likes a bit of back pressure and previous rolling road sessions have shown the de-cat to lose power from the engine, plus you WILL fail your MOT.

Get a sports cat from someone like Janspeed, its honestly the best bet for the BRM.
