I don't normally bash on other manufacturers' stuff, but I do take issue with the N1 being described as "top tier."
I've cut a couple of them open (to determine internal construction, and to figure out what happened to make the other one sound like a$$ all of a sudden).
Ask Dan (Dano here on NICO) about his expensive, supposedly all-stainless, Apexi N1. (hint: it's not)
Anyhow, to answer your question, two reasons: Stainless prices have gone bananas in the past five years. Not only do manufacturers have to figure out a way to absorb the cost of the raw materials (piping and bar stock) but they've also got to contend with increased costs passed on to them by suppliers... yes, even most of the supposed "top tier" JDM manufacturers get their components (mufflers, resonators, clamps) elsewhere (typically China).
The other reason is even simpler - fuel surcharges. It's really a multiplication of impact, since EVERYONE that touches that steel raises their prices... from the mill to the pipemaker to the wholesaler to the component supplier to the shipping companies to the exhaust builder to the retail store. Even if each one adds $5 to their cost, then passes it on, that can be $50-$100 more passed on to the purchaser.
We just suck it up, take the hit, and make less profit. I ain't raising prices, and I'll still sell exhausts if I lose $10 on each one.
