I just swapped the stock manual suitcase muffler with stock muffler from our automatic Z Nismo. manual stock exhaust already has straight mid pipe. Automatic muffler is also straight through design with cross over inside. Gets rid of highway drone.
not sure how cold it is in your area, these summer tires start to lose traction considerably when temps are below 50F. also try moving your seat back a bit to ease off pressure on the throttle. ;)
Came across this post other day. Around 4k discount including Nissan incentives on 26. Looks like they have 6 units in stock.
