The LIMIT+1 High Flow Downpipe for the 2025+ 4Runner is designed for enthusiasts looking to improve exhaust flow while maintaining reliability and drivability.
Each downpipe is hand built in-house at our facility in Crystal Lake, IL using premium 304 stainless steel and precision CNC-machined flanges for exceptional fitment, strength, and long-term durability.
Featuring a genuine GESi G-Sport 400-cell high-flow catalytic converter, the LIMIT+1 Downpipe provides improved exhaust flow and supports increased performance, with the greatest gains achieved through proper ECU tuning. Reduced back pressure helps alleviate any potential for valve float. Careful design and extensive testing ensure reliable operation while maintaining emissions compliance.
Every unit is individually fabricated, fully welded, and test fit before leaving our facility to ensure consistent fitment, exceptional quality, and long-term reliability.
