armydude52c Posted February 17, 2017 Share Posted February 17, 2017 I know it's probably been asked before but I just ordered the two brothers s1r full system and I want to install it but don't have my power commander yet. I know the bike will probably run lean now but my question is how bad would it be to go ahead and install the exhaust and run it for a week till the controller comes in?

jmacas87 Posted February 17, 2017 Share Posted February 17, 2017 @armydude52c make sure your O2 is hooked up, and use the baffle if you have it. You'll be fine. Your motor will not grenade Link to comment Share on other sites More sharing options...

fizzer7r Posted February 17, 2017 Share Posted February 17, 2017 Been running an aftermarket exhaust on my FZ for a whole season without a PC or any other type of fuel injection management and I've had no problems. Still going to get one this summer cause I want one, but I don't think running an aftermarket exhaust without one will do much over a short term, especially not in a week, and even more so if you drive properly and don't rev it to the limiter Link to comment Share on other sites More sharing options...
Beemer Posted February 17, 2017 Share Posted February 17, 2017 Army dude, it'll be ok but if anything does magically go bad because of it just tell some lower ranking guy to drop for push-ups until it gets better. Beemer Link to comment Share on other sites More sharing options...
crsnhppr Posted February 17, 2017 Share Posted February 17, 2017 I put close to 10k of near full time redline on my engine with a drilled exhaust, removed snorkel and snorkel plate...10k miles later she's still a sewing machine smooth. Unhooked o2 sensor some of that, removed air filter entirely a few miles etc. recently put an EJK on tho just because.. Link to comment Share on other sites More sharing options...
crsnhppr Posted February 17, 2017 Share Posted February 17, 2017 Like literally , did a 40 mile stretch over 110 the whole time, and many other times 5-10 miles redlined. I change my oil kinda often tho... every 1.5 to 2k miles Link to comment Share on other sites More sharing options...

Premium Member jake Posted February 17, 2017 Premium Member Share Posted February 17, 2017 That makes me feel better. Will be installing it first thing in the morningFYI I reused my exhaust gaskets on the head also no issue. If you got new ones use them though. 2015 FZ-07 2003 2014 GSXR 1000 Link to comment Share on other sites More sharing options...
