PSA: Little-known dealer factoids for tweaking performance on your couch rocket! 1st off, when I installed the V&H slip-ons originally, I used a high-performance 2x4 to make sure they were even! Wrong! You must install the business side 1/2" to 3/4" shorter. Being old skrewl I did not know this. And last but not least you must turn the lock key thingy precisely sideways (I know this because it says AccuSeal right there) before tightening the crossover clamp to get all that exhaust goodness you can to flow somewhat more performancy! I should be riding 🤪 Bye Y'all.
