T-304 Stainless — Only the Best Will Do!
Borla's 50 state legal exhaust is built of aircraft-quality stainless steel, inside and out, not mild steel, not aluminized, not aluminum, not just wrapped with stainless on the outside for show.
Coating techniques, such as aluminizing, can somewhat prolong the life of mild steel, but coatings suffer quality failures at the weld points. And comparing aluminized mild steel to T-304 stainless steel is like comparing gold-plated metal to solid gold!
T-304 Stainless Steel has the highest chromium and nickel content, making it the most resistant to corrosion and therefore the most desirable material for a long lasting exhaust system.
Performance — Designed In from the Beginning!
Borla's straight-through and multi-core designs increase exhaust velocity to move more air through the engine, allowing the exhaust gases to evacuate the cylinder completely, which allows the new charge to come into the cylinder, thereby creating more power! The acutal power increase that you will see depends upon your engine management system's ability to provide the fuel to match the extra air flow, but Borla states that generally 7 to 15% increases are not uncommon!
Most believe that big diameter pipes are the best for more power, but Borla has found that for street use, their pipe diameter choices help " maintain exhaust gas velocity and keeps the frequency high" to keep the main sound behind the tailpipe for quieter operation!
