I just replaced my stock dual cans with a single-side, high-mount Two Brothers exhaust I found on eBay. It's the carbon fiber black series can, which I don't think TB sells for the 919 but someone had adapted it to work with the S pipe for the 919. It sounds great! It looks pretty good, but may look better on a black 919. My photos aren't great.
Question for anyone who has done this conversion: Did your S pipe end up very close, almost touching, the coil spring on the rear shock? Mine is about 1/16" away from touching. I can't tell if that coil spring is painted red, or has a rubber-type red coating on it. Feels like paint. Either way, is the S pipe being that close going to be a problem with heat on that coil spring?
Also, the rear stock brake line was actually touching the S pipe when I got everything installed. I had to loosen the brake line connection closest to the S pipe and twist it outward a bit, and manipulate the whole line a bit to get it away from the S pipe. I plant to replace it with a stainless steel line soon.
Also, I didn't use any sealant at the connection of the S pipe to the stock header. TB says to use some Permatex black gasket maker, but it fit pretty tight, so I didn't use it.
Anyway, main question is as to the S pipe being too close to the spring on the shock. I'm no mechanic, so I would really appreciate if someone out there could let me know on this. I've attached a few photos.
Thanks in advance for any tips!!
And yes.... I do plan to get rid of that stock tail/snow shovel soon!
