IT’S BACK AND IMPROVED!
URD is proud to announce our new version of our Spec-U exhaust system for the 2003-2009 4Runner V6. This is the ultimate performance exhaust system for your truck and it is ready for the race track.
The Spec-U system differs greatly from our other exhaust systems and Y pipes. We took a totally different approach and combined an equal length Y pipe and cat-back exhaust system as one complete assembly. The system consists of an equal length Y pipe using 2.25″ tubing that transition 3″ exhaust that includes twin mufflers. It has a SIDE EXIT DUAL TIP ceramic coated in satin BLACK.
The Spec-U system will bolt to the rear of the stock exhaust manifolds/front cats, or the URD Spec-U equal length long tube headers, Doug Thorley long tube headers or the JBA long tube headers. The system is not compatible with any other Y pipe or cat-back system.
URD put a lot of R&D time into this system to optimize the tube sizing, bend locations, lengths and materials and the result is very impressive. The Spec-U system enhances power and torque throughout the RPM range and has a completely unique exhaust note. The exhaust note is more like the purr of a high end European sports car than typical raspy 4Runner V6 sound you have been used to. It is very quiet during highway cruising and has a very unique exhaust note when accelerating!!
The Spec-U system replaces the stock Y pipe and cat-back. It is easy to install with no cutting or welding and uses the stock OEM mounting locations and most importantly will properly exit the cut out in the body kit for the XRunner.
