Technical Questions Answered

What's the difference between turbo-back and downpipe-back exhaust?
Turbo-back systems replace everything from turbo to tailpipe while downpipe-back starts after the downpipe.

How much horsepower gain can I expect?
Properly sized systems typically yield 15-30+ HP by reducing exhaust backpressure.

Will a larger diameter exhaust increase turbo lag?
Properly designed systems actually reduce lag by improving exhaust scavenging efficiency.

Are these systems compatible with emissions equipment?
Race systems are designed for deleted trucks; check local regulations before purchase.

What's the advantage of 304 stainless steel?
Superior corrosion resistance compared to aluminized steel, especially in winter road conditions.
