I am currently trying to decide between the akrapovic exhaust and this one by RB Racing......
1. I like that it does not cover the dip stick
2. I like that it tucks up nicely and has ground clearance
3. longer tail or muffler portion should help with more low end power (so i was told...lol)
4. I like that the black version is actually triple coated..here is what they say about their ceramic coating:
We have a lot more people looking for durable ceramic finishes and we think we have the best finishes on the market. In the late 70's and early 80's we tried all sorts of coatings and paints and even used porcelain on some of our products in the late 1980's. The newer ceramic finishes are tougher and we use both Polished Silver Ceramic and Ceramic Black to complement our usual chrome offerings. The newest "Double Coat" Black finish is a double coat process that gives additional protection against scratches and nicks, providing two barriers against corrosion...Silver then Black on top of it.
I am not sure about the fact that these do not have a baffle in it...they offer a model that does have a baffle but I don't like the fact that it is so long...
I called them with concerns about not having a baffle and losing performance becaude of lack of back pressure, and they said that it is a myth and that with good tune should actually be better than an exhaust with baffle...as for sound I would imagine this thing is pretty loud due to no baffle, but then again there is an option to get the one with the baffle...

here is what they had to say about baffles and back pressure:
Over 25 years ago we stopped putting in any form of removeable baffle in any of our designs for one simple reason...They can come out. Now that may seem obvious i.e. a removeable baffle should be removeable by definition. The problem arises when they fly out if that 1/4" x 20 bolt gets loose, and the baffle goes bouncing down the interstate and goes through someone's windshield, usually a Mercedes. This is the reason we do not make any removeable baffles. Putting spring loaded valve gizmos in pipes is nothing new, it was done over 30 years ago.

In the case of the LSR 2-1 Pro Stock Designs we have set the I.D. for maximum performance. There is no room for a baffle and we don't want one in there. If you are looking for a Pro Stock design with some form of baffle we offer the LSR 2-1 Pro Stock Spyder.
Washers, butt plugs, tennis balls, spring loaded diesel truck rain flaps....anything you add, insert, graft on etc. will change the performance. Stick anything in there and you defeat the purpose of the Pro Stock design. We offer a wide range of pipes with internal baffles. LSR 2-1, LSR 2-1 Black Hole, and LSR 2-1 Pro Stock Spyder. We are the only manufacturer that does.
If you want to make power on a multi-cylinder engine you have to use a collector system. Whether it's a V-Twin or a V-8 it's the same, and no less an authority than the famed engine builder Smokey Yunick will tell you that. Not using free exhaust energy to help your engine breathe is downright criminal. No matter what the conventional wisdom is, staggered duals on a Harley will not make more power. You simply cannot escape the fact that a properly designed 2-1 will give you more useable torque where you need it, in the 2000 to 4000 rpm range, which means less downshifts and less rpm to get the job done. A set of short staggered duals at peak rpm can be made to produce good power but they will be dead on their ass until they get there, whereas an engine developed around an LSR 2-1 exhaust can be made to perform from the bottom up with no dips in the torque band!
Our testing has shown that the Harley V-Twin is extremely sensitive to back pressure which is why 2-1's that use small or restrictive collectors don't breathe well, and why restrictive baffles shut the motor down. Disc type baffles are good for spark arrestors on dirt bikes but they have no place on a big inch V-Twin. You don't make power by adding restrictions to your exhaust system whether it's a bunch of stainless discs or some damn piece of aluminum billet machined into a Harley butt plug! Ever wonder why they had to put a hole up the center of the discs? Well, one reason was the discs are so damn restrictive you have to have several pounds of them to get enough flow through their waffle shaped passages. Good mufflers, but they have nothing to do with performance and they sure as hell do not create vacuum as has been claimed. When you get confused by all the bullshit simply ask the following question.." Do they run them in NASCAR or in Formula One?". Nope, they run straight pipe collector systems without any stupid discs or aluminum butt plugs.It's always funny how when the money is on the line, all the little things like discs, billet caps, anti-reversion flaps, reverse megaphones and other such nonsense somehow don't make the field.
f you look at any other "pro" or "king" self-proclaimed winners of the typewriter wars, take a close look ar their collectors and their tail sections and imagine yourself being propelled at 5000 feet per minute past your exhaust valve headed for the Honda Goldwing you just blew by at 115mph! On your LSR Pro Stock you get a rocket boost out of the gate when you hit our CNC machined turbo venturi...On the other pipes you either run into a jagged weld or some necked down piece of torky-porky poor engineering. Headed for the collector on your LSR Pro Stock you can see the Goldwing, so you point your toes anticipating a maximum velocity exit to freedom...On the other pipes your asshole puckers and your mouth goes instantly dry as there are a barage of aluminum butt plugs, stupid discs 90 degrees to your path, and an assortment of flat airfoils and anti-reversion tank traps waiting to rip your guts out! Get the picture? This isn't rocket science. Just build a clean system with a gentle smooth flowing collector and the rest will take care of itself.
All RB Racing LSR Exhaust Systems feature our "new" (we've been quietly doing it since 1985!) CNC machined Turbo Venturis that actually "scavenge" to help your motor breathe. Machined from billet, these allow full 2" flow and eliminate the phony restrictions that other 1 3/4" to 2 1/4" pipes have at your exhaust port.Our competitors must think you won't notice that they neck their 1 3/4" to 2 1/4" pipes down to as small as 1 1/2" to mate them to your exhaust ports. RB Racing's Turbo Venturies are expertly heliarced to each primary tube eliminating any internal obstuctions and insuring the maximum flow from each exhaust port. RB Racing won't build phony performance pipes...We sure as hell won't ask you to port your heads, put in bigger valves and a high performance camshaft then stick a bunch of stainless steel discs or machined aluminum butt plugs in the pipe to restrict the flow! And we damn sure won't put some silly "1950ish" reverse megaphone pipe with internal flat plates, baffles and air foils to screw up your performance. Our pipes make anywhere from 6 to 18HP over these stupid designs.
