FAQ
How does the 1.00 A/R drive compared to .91 or .88?The 1.00 A/R favors top-end flow and lower EGTs at sustained load. The .91/.88 A/R options typically spool a bit quicker; choose based on use, gearing, and desired powerband.
What power level is the 64/74 good for?As a guideline, the 64/74 SX-E supports strong street/tow builds when paired with proper fueling and tuning. For higher peak power, consider the 66/74 variant listed above.
Does the kit include the downpipe?Yes — this kit uses a high-flow HX40 downpipe as listed in the features.
Is this legal for on-road use?No. Industrial Injection designates these performance products for closed-course competition only. Check and comply with all laws in your area.
