For turbo, you want the LEAST amount of backpressure possible so removing the cat is actually a great thing.

Oh that makes sense. But still, I'd rather spend a bit more for quality
Besides wouldn't I need to retune with straight pipe also? My whole point of trying to keep stock manifold is so I do not have to get a retune because I cannot trust the tuners here 100%. So I'm just wondering how safe it is to keep the stock header with the PTuning kit.
