No emissions here. I was just checking to make sure it wouldn't damage anything. Thanks.

Well, after you boosted too much from freeing up the exhaust, yes you could damage things. More boost and no added fuel=detonation.

Be careful. If you put a free flowing exhaust and don't tune your fuel then you have a good chance of detonating. Also it would probably be a good idea to port your wastegate to prevent from overboosting.
