Premium Member slow06er Posted January 1, 2016 Premium Member Share Posted January 1, 2016 Anybody knows the size of the outside diameter to the exhaust pipe that comes after the O2 sensor ? Link to comment Share on other sites More sharing options...

philthyphil Posted December 26, 2016 Share Posted December 26, 2016 I know this is an old thread but I'm just wondering if running straight pipes like that changes the way the bike runs? Link to comment Share on other sites More sharing options...
booboobusfz07 Posted December 26, 2016 Share Posted December 26, 2016 I know this is an old thread but I'm just wondering if running straight pipes like that changes the way the bike runs? Any change to the exhaust or intake will change how the bike runs. The ecu can compensate, so anything will run ok. Youll get best results with a fuel controller of some sort tho.

The ecu can compensate, so anything will run ok. Youll get best results with a fuel controller of some sort tho. That's not true. Straight pipes will run like garbage. All the dirt track guys who use this fz07 platform for racing thought that the straight pipes with megaphones where the best because it's what all the old-timers said. Then Yamaha and Graves got together and developed a pipe that made 18 hp more than the best pipe .Now all of the Dt07 racers have shifted to the Graves system.. don't believe me, check it out for yourself and do a search Link to comment Share on other sites More sharing options...
Premium Member slow06er Posted December 27, 2016 Premium Member Share Posted December 27, 2016 I did something a little different I bought the double down exhaust from Toce for the R6 cut the cat off and welded the flange from a stock R6 exhaust on to the collector. Then I installed the double down which has no baffles so it's pretty much straight piped and is super loud but it sounds great except when you decelerate there's a bit of backfiring from the loss of back pressure so I'm going to fabricate a baffle. Actually when I talked to Toce they said there were working on a baffle for the double down so I need to call them and check on that first. Best part about it though is it looks amazing on the bike. Best looking exhaust I've seen in my opinion. @christrix - Have you finished your Toce exhaust project ? , can you post some pictures of your Toce exhaust and your bike ? I wanted to do something similar to my FZ07 a while ago but I never got to do it. I would like to see your final results. 1 Link to comment Share on other sites More sharing options...

BS. For something that is 67HP from the factory, 18HP+ from a pipe would be equivalent to discovering how to travel at light speed. I did a search. I can't find anything about it.

howlinhoss Posted December 27, 2016 Share Posted December 27, 2016 In addition to needing a fuel controller, in my opinion it will be insanely loud and you will probably annoy alot of people. More noise does not always = better. Link to comment Share on other sites More sharing options...

You should attend a pro dirt track race and ask the guys racing them. A local team that does dirt track racing did the testing to confirm what the engineers at Yamaha told him. The results where confirmed. The top exhausts systems in dirt track that the tested against where Bub and Ron Wood. Link to comment Share on other sites More sharing options...

Haven't heard anything about it since. Either way, that bike was ~90hp with ported cylinder heads and intake stacks, modified/tuned air box with K&N filters, and, yes, a Graves exhaust. cycleworld [a href=http://www.motorcycle-usa.com/2015/10/article/yamaha-unveils-dt-07-flat-track-concept/]motoUSA [/a] 1 Link to comment Share on other sites More sharing options...

I thought bbstein was insinuating graves alone achieved those gains No not at all. What I was saying is that straight pipes run poorly. All of the top dirt track guys for years had been running non silencer type systems and then Graves and Yamaha developed a pipe that made 18 hp more than the best of the other top level dirt track pipes for the Fz07 platform. I would not have believed that either but the guys from the G & Graves team told me this at a race. I was in disbelief as well. However I spoke with the engineer who was in charge of that project and he confirmed the gains with the Graves exhaust and that every team using the Yamaha engine platform had switched to the Graves The Dt07 makes a 100 hp for your reference.

Slash Posted June 11, 2019 Share Posted June 11, 2019 Hi, were you able to find a baffle for TOCE double down? I have a yamaha R6 with MJS mid pipe with Toce double down and it is obnoxiously loud and looking for a baffle insert/db killer. any help is appreciated Link to comment Share on other sites More sharing options...
