PRL built the N1 around a single-exit design using 16-gauge 3" 304 stainless steel with smooth mandrel-bent transitions — the single exit keeps weight and cost down while still delivering a real performance gain. Engineers carefully calculated tubing length, bend placement, and muffler/resonator specs to hit an aggressive but tame sound that avoids the drone most aftermarket exhausts are known for.

Aside from the 3-bolt front pipe flange, every connection is slip-fit for easier adjustment and installation, and the muffler is supported by a clamp/hanger assembly rather than a welded hanger — better for long-term serviceability. Everything is TIG welded and fully back-purged to handle exhaust gas temperatures and outdoor exposure without degrading.
