If you’re modifying a 2.0T Honda or Acura platform, do your own research and don’t rely on marketing hype. I say this from experience — I’ve owned and run nearly every major downpipe on the market.
Somewhere along the way, heavier and more restrictive downpipes — typically using 400-cell catalysts — became the industry norm. In my opinion, that shift benefits manufacturers far more than customers. Restriction is restriction, no matter how it’s marketed.
That’s why what Axion has done genuinely stands out.
Axion’s downpipe is simply on another level. If you understand the fundamentals of flow, flexibility, and power, the design speaks for itself. A true 200-cell option with a race-only catless swap capability is virtually unheard of today — yet Axion delivers it without compromise.
While many big-name brands rely on polished marketing language, Axion focuses on engineering first. Even the hardware matters: Axion uses Clampco Products V-band clamps, a USA-made component trusted across aerospace, motorsports, marine, and high-performance automotive applications. That alone tells you the standard they’re building to.
After extensive research and hands-on experience, the choice became very clear. I want the best for my Integra Type S, and Axion delivers exactly that.
Just as important is the people behind the product. Mike, the owner, is accessible, knowledgeable, and genuinely cares about building the right platform — not just selling parts. No automated systems, no disconnected support — just accountability and passion.
If you’re serious about performance and want engineering over marketing, Axion is in a league of its own.
