fullclip Posted April 13, 2016 Share Posted April 13, 2016 Can anyone post up a dyno chart on the Ixil system? I know everyone bash's them but I don't notice any loss with mine at all? Show me please! Link to comment Share on other sites More sharing options...

Show me please!This has been posted in several locations, but here you go: http://fj-09.org/thread/3394/fj-current-exhaust-flash-options As you can see, it makes 4 HP less than stock. 4 isn't something you're likely to notice, but it's 12 hp less than the best option, which you definitely would notice.

Premium Member foxedupone Posted April 13, 2016 Premium Member Share Posted April 13, 2016 Can anyone post up a dyno chart on the Ixil system? I know everyone bash's them but I don't notice any loss with mine at all? Show me please! You get more noise so it feels faster then stock probably. Danmoto is definitely the boss of the exhausts and it's one of the cheapest, so great value there as long as the craftsmanship, materials used and fit is ok. Still I'd like to see that graph overlaid to see if the bottom end still holds up in comparison and that the great top end is not at the expense of losing power lower down but it doesn't seem that way. Big gains usually add gains throughout the range. Link to comment Share on other sites More sharing options...
zachd Posted April 13, 2016 Author Share Posted April 13, 2016 The Two Brothers system just got delivered today. Off to install it! Looks so purdyyyy. Link to comment Share on other sites More sharing options...
fullclip Posted April 14, 2016 Share Posted April 14, 2016 So how often do you guys ride above 8 grand on your fj's with aftermarket exhausts? Any idea how much the stock exhaust weighs? Does everyone's FJ make the same power stock?? Of course not. If Joe had a fj with a graves system on it and he himself weighs 250 lbs. Then take Mike who has the same bike and exhaust but he weighs himself 220 lbs. Who's bike is faster and who's bike is making more power?? So how many guys are still riding above 8 grand?? Often? Only on your way home from work? Or may even a quick ice cream run? Link to comment Share on other sites More sharing options...
fullclip Posted April 14, 2016 Share Posted April 14, 2016 Another statistic for you guys is if you trim 7 pounds off your bike you should gain 1 hp? True or false? Link to comment Share on other sites More sharing options...

And it's not just about power but also about throttle response. It's a completely different bike with the exhaust and flash. Link to comment Share on other sites More sharing options...
rocky5000100 Posted April 14, 2016 Share Posted April 14, 2016 Another statistic for you guys is if you trim 7 pounds off your bike you should gain 1 hp? True or false?You're not "gaining" horsepower. You are simply lowering the weight per horsepower ratio. For example if you and your bike weight 640lbs (440 + 200), and your Ixil exhaust bike makes 103 hp, your pounds to HP ratio is 6.213 lbs/HP. Losing 20lbs of fat will change that ratio. 620lbs / 103hp = 6.019 lbs/hp To achieve that same lbs/hp ratio using horsepower, you would have to gain ~3.3 horsepower. 640lbs / 106.3 = 6.020 lbs/hp So while horsepower and weight are not the same thing, a lower lbs/hp ratio is generally better, and will make for a faster bike in a straight line. However, a LIGHTER bike will handle better in the corners (everything else being equal). And because I'm bored today at work: choosing one of the exhausts on here that makes 115hp, gives you a weight per horsepower ratio of (640lbs/115) 5.565 lbs/HP To achieve that ratio using weight loss and the Ixil exhaust, you would have to lose 67 pounds between you and the bike. 5.65 lbs/hp x 103 hp = 573 lbs 640lbs - 573lbs = 67lbs Link to comment Share on other sites More sharing options...
fullclip Posted April 14, 2016 Share Posted April 14, 2016 Nope I never take my bike above 6 grand ! I'm scared!! Link to comment Share on other sites More sharing options...
hornetmike Posted April 14, 2016 Share Posted April 14, 2016 Somebody on the graphs thread said the Ixil is the only aftermarket pipe with a Cat. Is this true and has anyone tried removing it? Link to comment Share on other sites More sharing options...
traceroz Posted April 15, 2016 Share Posted April 15, 2016 Nope I never take my bike above 6 grand ! I'm scared!! Yes, scared that your Ixil exhaust will fall apart and jam in the rear sprocket. Link to comment Share on other sites More sharing options...
zachd Posted April 15, 2016 Author Share Posted April 15, 2016 Somebody on the graphs thread said the Ixil is the only aftermarket pipe with a Cat. Is this true and has anyone tried removing it? It's not removable. Look at my picture of it from the first page. The Akro system has an optional cat you can install. Other than that, I don't think any other aftermarket system has a cat.

fullclip Posted April 15, 2016 Share Posted April 15, 2016 The cat on the Ixil is removable, I drilled mine out. This forum I find very humorous like I said before opinions are like butt holes we all have them Whatever works for you may not work for me and every bike is differant,no matter what exhaust,what flash, and what the air temperature is on any given day. I was on some back roads yesterday south of town air temperature was 53 and I had my FJ pinned WFO 158 mph! I never ride above 6 grand!

hornetmike Posted April 15, 2016 Share Posted April 15, 2016 I'm not getting the power loss thing - compared to a reflashed stock exhaust, yes, but not standard. Is the graph for the Ixil reflashed? Those Dan Moto exhausts look to be amazing value - whether shipping and import duty from china makes it less so, I don't know. Tempted by the one with on the fly adjustable baffles - nice and quiet so you don't wake the neighbours, then open 'em up! Link to comment Share on other sites More sharing options...

I always it was 8lbs = 1hp. Your math shows it's actually 6lbs. I like you math better! Link to comment Share on other sites More sharing options...
