Have had several Cat-Backs on my 4Runners and always felt something was missing. TRD Cat-back-Loud and droned, Borla Cat-Back Nice-but left with OEM Y-Pipe so just increase in volume. URD 3" MK1 Cat-Back - Did notice some butt dyno increase-just loud and installed Vibrant resonator to tone down
Changed out to this combo this weekend and very happy with outcome.: URD Y-Pipe and Borla Touring Cat. The URD Y-Pipe fit perfectly. The Borla install fit to the Y-Pike without issue. Put a 1 1/2" wedge into the rear Hanger and this dropped the Borla Exhaust tip 1/2" off the bumper. Started up and no CEL's and off the driving. Just the right tone and feel the difference with increased flow from the Y-Pipe. Definitely pulls better standard around the town driving. 100 miles of mixed driving and seeing improved MPG----will see once I fill up
