I'll wade in here just to say that Merlin is exactly right about an extra bhp costing a lot more money.
I was offered the 'next step up' as it were when I got my work done - it would have put me in the 270-280 range, but without getting too in depth would have cost a good few thousand on top.
What I like about my build and the reason I went for it is that it's mainly Honda parts, with a little extra fettling and a few choice goodies, which should mean it's very reliable. I know that sounds daft after what just happened but that was the dizzy

not the engine. Plus, I didn't want something too edgy, my car is my daily driver, I just wanted Lude+, and that's exactly what I feel I've got.
Unlike Ratty's comment, and no disrespect whatsoever, I don't feel like I have a ticking timebomb attached, I still feel like I can push the car and I'm not asking for trouble. that's how it
feels anyway
Oh and one last thing on the exhaust - Mine is a 2.5" header by solid fabs, into a 2.25" (decent dealer) powerflow cat back, so the decat is tapered.
My car certainly doesn't feel restricted and the numbers wouldn't suggest otherwise, but it will be interesting to see what difference a full 3" system makes to Merlins car.
I'm old and that would just be too darn loud for me
