Barely used Two Brothers performance exhaust for F3 models. Came on my like-new, used 2015 F3S, it had only 350 miles on it when I picked it up this spring. The exhaust wasn't my cup of tea (too loud), so I found a like new stock exhaust on Ebay and paired it with a new cat delete pipe. Much more my style. Nothing at all wrong with the exhaust. I have 1400 miles on the Spyder now, and it has always been garage kept. I tried the P1X power tip to quiet it down some, and it did. I will be leaving it on the exhaust for next owner. The power tip can be removed in just a few minutes. $375 shipped to you in the lower 48. It will come in one piece as the two pieces appear to be heat fused and I don't want to damage anything by forcing them apart. Excellent value if you are looking to change out your pipe.
