I have the Big Radius...but I'm sure the Twin Slash Staggered is about the same. 2-3 hours...not hard at all. Just follow the directions.Ernie said:Thanks skwerlee is it a hard install?
+1!skwerlee said:You'll need gaskets though. Dont get them from Yamaha. Use Felpro #23588........$1.99 at OReilly's
Twin slash does not come with O2 extension... at least mine did not. But, nothing extra is needed to complete install... I had some extral copper O rings for the headers.. but did not need them, the originals were still fine.skwerlee said:It comes with the O2 extensions. You'll need gaskets though.

Glad it worked out for you but as a rule of thumb its best to replace the gaskets anytime you remove the headers. It's cheap insurance against leaks. Would hate to have to tear the entire exhaust system off after the fact just to fix a leak because i didn't wanna spend $5 on gaskets.SFCMcGan said:Twin slash does not come with O2 extension... at least mine did not.

Also.. not sure about this mind you... even with a dyno run... what can be done to increase air/fuel mixture... we are all running fuel injected engines... what can be adjusted to compensate for the exhaust, intake etc...? Personally... I love my cobra autuner....11Stryker said:A load of crap[ cost of non PCV and Dyno run far outweighs cost of PCV and everytime you want to change something you will need another Dyno run PFFFFT!!mikoloe said:If your gonna do it! change the Air intake while you are at it and take it and put it on a dyno! dont mess around with the PCV crap!dont need it!
