I put the boost back into it but the 5" open pipe definitely makes more power. If you have a lot of overlap, a smallish exhaust wheel, tons of exhaust from the E85, and a restrictive exhaust I can see where you'd have some problems. My $.02.

Funny you say that , I just had a new custom 3” stainless exhaust ran out the back from my old 2.5 pipes system with a transverse muffler and after that is when it felt a tad slower ... but I should have helped the back pressure by going to bigger pipe and a 3.5 “ downpipe ....I have a new harmonic balancer coming and I hope that the timing marks are not accurate with my old professional products one . Thanks , will let u know what I find out with the balancer .. do you think 2-4 degrees off of timing can wake up a turbo motor ??
