About this product

Part #: 48-36602-HC

This race down pipe uses a unique resonance chamber to capture sound waves and minimize in-cab resonance producing an aggressive tone on throttle with a smooth sound at cruising speeds without effecting performance. In recent testing, the race version down pipe produced +14 horsepower and +39 lbs. x ft. of torque. The high-flowing down pipe is designed using mandrel-bent, 304 stainless steel tubing for optimum flow resulting in added horse power and torque. The down pipe is 100% hand TIG-Welded and uses a 3-1/2" into 4" stepped design that increases exhaust velocity and eliminates low pressure drops which helps to scavenge the exhaust for increased intake charge and more power.

What made you choose this particular product?
AFE concluded an intake spacer with rifles would allow better peak torque to be gained earlier on. I believe this is due to flow harmonics
What were you trying to accomplish by adding this product?
Give myself more peak available torque in the engine, especially in the early mid range where it seems it has a huge dip in power. and delivery
Was it easy install? Any installation tips that will help others?
Yes, Follow the instructions. I painted the spacer black instead of the brushed silver look it had. I like the stealth look for it.
Once you’ve had a chance to use the product, did it meet your expectations?
It has met my expectations, but I have not dyno'd it yet to prove if its worth it or not. My set up is unique and would require its own tune and results might vary.
Any additional comments?
I would recommend this bit as a stocking stuffer for Christmas time.
