zeitgeist57 Posted February 6, 2015 Report Share Posted February 6, 2015 My friend is making all-titanium exhausts for Harley's...starting with his own Forty-Eight. Looking for thoughts/opinions on style. The big option will be a variable flow valve to control sound, but for now this first system is a standard, loud exhaust system. This shows Stainless steel shields, but there will be an option for Ti ones as well. http://i.imgur.com/LXlqExb.jpg http://i.imgur.com/2mlwZwX.jpg http://i.imgur.com/XXdXyXa.jpg?1 (blocked out the brand name he's going with. ) Quote Link to comment Share on other sites More sharing options...
Rocky31186 Posted February 6, 2015 Report Share Posted February 6, 2015 I think it looks too much like a sport bike exhaust, I think everything up till the muffler looks good but the back half needs changed. Edit: I like keeping 2 pipes not going 2 to 1. Something along these lines. http://i801.photobucket.com/albums/yy296/rocky31186/Mobile%20Uploads/Screenshot_2015-02-06-08-00-08_zpstpdsqjao.png Quote Link to comment Share on other sites More sharing options...
POS VETT Posted February 6, 2015 Report Share Posted February 6, 2015 He can make/weld titanium exhaust? What else can he do with titanium? Quote Link to comment Share on other sites More sharing options...
Geeto67 Posted February 6, 2015 Report Share Posted February 6, 2015 Let me ask a few questions: - is it a true equal length system? - what's the ID of the pipe? - has he dynoed it yet? I like the way it looks ok, not a fan of slash cut mufflers, and that merge collector seems a little dubious but if it is going to work like I think it is going to work he should see a bump in torque because of it, provided he didn't make the pipe too big. Since Ti is usually thin wall stuff that's what I am guessing he used and the pipes may be a little big for the application. Sporty owners usually like the look of big diameter pipes, and the stock pipes link big but on some models the pipe is pretty thick and sometimes even double walled, so the ID is only 1 5/8 inches. Most aftermarket exhausts for Sportsters are 2" or greater and most of them are great for stealing hp and turning it into noise. Exhaust design is all about exhaust gas velocity management and the larger and more unrestricted the pipe is the slower the gas charge, the collector design should put some restriction back and so would the muffler but I am interested in how the pipe performs.

turbospec29 Posted February 6, 2015 Report Share Posted February 6, 2015 Looks awful from the Y pipe back. Quote Link to comment Share on other sites More sharing options...
zeitgeist57 Posted February 6, 2015 Author Report Share Posted February 6, 2015 Thanks for the feedback, guys. He's also coming up with other designs. Let me ask a few questions: - is it a true equal length system? - what's the ID of the pipe? - has he dynoed it yet? - Front Y-pipes are less than an inch difference in length - 47mm = 1.85" I.D. - Not yet. Good call though... Quote Link to comment Share on other sites More sharing options...
cstmg8 Posted February 6, 2015 Report Share Posted February 6, 2015 Haha, reminds me of the old stinger exhaust for Baja bugs. I'm sure it'd sell a few simply for being different, and he can probably make a few variations. Everything up to the y is the hard part.

I would like see any dyno results. Quote Link to comment Share on other sites More sharing options...
Richard Cranium Posted February 6, 2015 Report Share Posted February 6, 2015 I've never been a fan of the 2 into 1 exhausts, but it's purely aesthetic though. I just don't like the way they look. That aside, it does look like he is doing nice fab work. Quote Link to comment Share on other sites More sharing options...

wnaplay1647545503 Posted March 2, 2015 Report Share Posted March 2, 2015 Does not look like it flows with the bike. Quote Link to comment Share on other sites More sharing options...
Green Bastard Posted March 2, 2015 Report Share Posted March 2, 2015 Puts me in mind of the new 750cc Harley they came out with last year. There are obviously differences, I like the one on the 750 better myself, but I also am more of a fan of the dual pipes. http://thekneeslider.com/images/2013/11/street-750-r.jpg Quote Link to comment Share on other sites More sharing options...
35RFTW Posted March 4, 2015 Report Share Posted March 4, 2015 I think it looks great other than the heat shield on the muffler. Does look like a sportbike exhaust yes, but that's also what makes it unique and not like every other damn sportster exhaust around. Quote Link to comment Share on other sites More sharing options...
zeitgeist57 Posted March 4, 2015 Author Report Share Posted March 4, 2015 Just got an email from my partner...he's got a Softail Breakout in his factory for exhaust development. The "Kick" model above is being done up in titanium and I'll be getting product this month!:thumbup: I do appreciate people's feedback. More to come as we get this off the ground.
