Quick Overview

Give your E53 X5 a unique deep sound with no drone with this Supersprint Resonator! Supersprint designed this resonator section to replace the stock resonator when used with their headers, section 1 cats, and rear mufflers. This resonator is a free-flow design that is also tuned to produce a low exhaust rumble sound and give the X5 V8 more presence. (787103)

Unlike many high performance exhaust systems Supersprint has developed a resonator that will NOT reduce power, only that annoying drone and loud exhaust sound when cruising at a low rpm.  This Supersprint resonator will leave you with a one of a kind deep rumble.  It is designed to make make the rest of your Supersprint exhaust nearly unnoticeable in the cab at cruising speed but once your step on it, the exhaust will come to life to show everyone you mean business.

All Supersprint resonators are of the flow through resonated design. This means each unit has no chambers or baffles to reduce velocity. Simply, a straight through in & out design! The internal components are 100% stainless steel with a high heat resistant rock wool sound suppressing material, not found in any other systems. This is the reason we can offer you sound legal performance exhaust systems. Tubing is always mandrel bent for maximum flow. Flanges and hangers are O.E. or better quality for a perfect fit every time. Housings are all manufactured from 1.5mm material that is M.I.G. welded at all seams. The stainless systems are 100% 304 stainless, the mild steel systems are aluminized on the inside and out, then black heat coated for corrosion prevention.


  • Increased performance horsepower and torque gain
  • Quality product made of 100% Stainless steel
  • An amazing 3 year unlimited mile warranty
  • Great deep tone
  • Maximized exhaust flow
  • Superior fitment
