OK so I have decided to sell my buell race muffler and have already removed it.I am going to put straight pipes on and have photo shopped a pic.I know I will lose power but I want it to be so loud it just pisses people off.I would like to hear if you think it will look right or if it will cause any problems.I plan on putting the dual exit tips on both sides which would be 4 exits 2 on each side the header into a Y pipe into 2 single pipes one on the right and left/ then those into the dual outlet tips All straight pipes........>>>

To be honest I feel like thats going to be bad for your bike. No backpressure or nething.

Also, if you are set on running straight pipes i think ur photoshop makes it look bad, dont ru nthe pipe all the way to the back, dump it behind the chin spoiler or soemthing.

With such free flowing activity and no compensation with regards to air/fuel adjustment, I'd be worried about the toasting of the valve train.

how can sporsters run straight pipes and not toast their valve train but we can't? aren't they RELITIVLY the same motor?

I already have the race ecu and airbox delete with the K/N filter will that help the air to fuel ratio as Glitch stated?Also Tommy5144 I am running them as long as I can to keep the heat behind me and make the pipe longer which should help a little.Also I am going to wrap them from the header to the end.

If you want to keep some backpressure on the engine, just use "T" insteady of a "Y" to split the 1 into 2.

Should be insanly loud.

My recomendation would be to keep your race pipe until you know that your new system works, and that you like it. I would take it for an easy ride of maybe 10 miles or so and then check the plugs. If all looks good, burn a full tank of fuel through and check the plugs, just to make sure its running a good AFR. If all looks good, I think you'll be in good shape.

Ideally you'd want to put it on a dyno with a wide band O2 sensor and see where its and and tune if necessary.

Because they put fewer miles on their bikes in a year then I did last December in Ohio? ; )

The length of the straight pipe will tune the system for max HP at a narrow RPM range. For drag racing ("drag pipes"), this would ideally be near redline, so you would maximize the power output of the bike. And you would want to jet it for that max airflow.

There are a couple factors in play... first the inertia of the moving exhaust will help "suck" a fresh charge through the intake during the valve overlap period (both valves open). Secondly, the reflected shock wave from the exit point of the pipe can reflect back, and effectively act like an exhaust valve helper, allowing you to get more aggressive with cam grinds and cam timing, it effectively puts you closer to having a "square" cam, which would be the most efficient shape were it possible.

Of course, you won't be changing cams or cam timing, so those are no benefit. And your stock fuel map will (if you are lucky) run way rich at low RPM, and not too lean at high RPM. If you are running lean at high RPM, the symptoms include melted pistons and valves, so you might want to watch for that. If that happens, rebuild your engine, change the fuel map, and try again. 7 or 8 rebuilds should get you in the ballpark ; )

It'll be really loud though. That'll be great fun for all the people that like really loud bikes, during the times they are in the mood for a really loud bike.

the diameter of the pipe and it's length are how sporty's can run 'em (correctly). when they run 2" shorty's they lose all their power. on a 1200 I think i heard that 1.25" diameter and apx. 3' long straight pipe is what works best for the needed back pressure. Mnbueller is right, keep your race kit untill you know you like your setup. It's your bike do what to it. I say louder the better. I grew up around harley's so i like 'em louder buy i personally don't want to sacrafice power/torque. You could rout the pipe under the bike back and forth to get the needed length. I'd hate to hear you burned a valve or piston, just be careful.

Ground clearance when leaning to the right? Just a thought. You could run a D&D pipe, they are by far the loudest pipes I've heard for XB's.

keep in mind this is just a photoshop pic when I put it on the bike I will make it fit right thats not the problem.I was wondering what size pipe should I use from my header to my dumps?I was thinking like 1.8125 in.....

To get the loudest affect you should turn the pipes away from the street and directly up with a 3' extension. Now that will be freak'n loud! Do it!

If you're really gonna do this make sure you get it tuned (or do it yourself.) It is going to take a lot of work if done yourself, but the power gains are worth it.
I currently run the gen I Force exhaust with the American Sportbike opened air box and used a wide band O2 sensor (Daytona Sensors) to tune my bike. It sounds like opened exhaust (actually it is) and pulls VERY strong.
Today I rode my buddies 06 City X and it felt like it was standing still compared to mine. If you tune it right I think you will be happy!

If you have any questions PM me.

Could you elaborate on the sensors? Or pm me?

I am getting ready to tune my bike, and would appreciate any and all the info you care to share. Thank you

"Brewtus,

Yes I would also like some more info on this I am used to tuning V8's not V-twin's.I will take it to a qualified person to do it but I would like to know about what you said rob..."used a wide band O2 sensor (Daytona Sensors) to tune my bike."I ordered the pipes last night and my pops bringing over his T.I.G. welder today I have to call a friend at a local exhaust shop so he can do some bends for me when I get all my measurements and moc up done....

Again I thank you for any help you can give me
thanks,SAINT

Also Mnbueller I took your advice and bought a "T" instead of the "Y".I think that will be easier to make a mount plate so I can put my chin fairing back on.I also was looking at the D&D exhaust and am going to steal there idea about putting a jack plate on the bottom which will also act as a skid guard.I bought the thick walled 1.8125 in pipes so I can weld it without any worries of burn through.I am A.S.E. master tech and I-car platinum certified and have been doing heavy collision repair for years so I should be able to make this fairly nice and easy and I have built 2 drag cars a 62 nova and a 85 buick T-TYPE.....But I always appreciate any info or ideas any one can give me as I have got some great info already so please keep them coming....

Thanks,SAINT

Use a megaphone pipe instead of a straight pipe from the header to the exit if you really want the loudest possible setup. Then it would look and sound more "Limey" than "Mexican".

Do whatever you want 'cause it's your bike.

For the best results you should use a wide band O2 sensor. It reads a lot faster and more accurate than the narrow band sensor the bike has now. The Daytona sensors WEGO log lets you data log TPS and RPM. Go to the ECM Spy site and read the tuning guide because That seems to be the easiest way to tune and data log. Don't forget to have you're bike up to temperature or you will be fighting yourself when adjusting. The tuning guide from American sportbike is also VERY well written.

first off Darryl Salmon,and rob Kazen obviously have no class.I only posted on here to get actual info and details not hear punk cowards talk $h1T.I appreciate any actual help given and wish some people would just shut up if they dont know enough to actually help.As brewtus said it is my bike and if I dont want to ride around looking like everybody else I would say thats a good thing.I mean anybody can go buy a bolt on set up I just prefer to try something else if it doesnt work I will keep me race exhaust for backup.Im sorry if I said racist I am just saying what the 2 idiots stated above really had no place in this post.Again thanks to all that are helping and have class.

My understanding was that you don't need backpressure but proper exhaust tubing to promote scavenging.

I live in East L.A. So i can honestly say this whole project is a bit Mexican. We are a group who will design out any and all practicality so that it has the right Look and sound in our vehicles. I need only point to lowrider bicycles with air suspension so they can jump like the cars, that have chromed welded chain link steering wheels and a 12 inch sub-woofer. Now that is Mexican, and so what! If that's what you like, who gives a $hit. build it and be happy.

I would be a little concerned about scavenging and not being able to tune BOTH cylinders for proper Air/Fuel.

As it is, the oxygen sensor changes the map on both cylinders the same amount. If your pipe changes scavenging only a little bit, it's probably going to be OK - but you won't know without a few dyno pulls.

What you CAN'T afford to have happen is to have a point in your map that is running too lean and melting a piston.

Whatever you do, do a dyno run after you've done it up. Get ECMSpy or another system that will let you completely tune front and rear cyclinder separately.

Good luck, have fun, (and take pics!)

SlowXB12r:
relax dude... there's nothing wrong with being from a foreign country. No go put some DINGLE BALLS on the windscreen and FUZZY DICE on the rear view mirrors to complete your look. Maybe some bouncy hydraulics -- yea, that'll look cool!

Combined with your exhaust, you will be the center of attention and truly do what you said you wanted to do:

"...I want it to be so loud it just pisses people off"

Go for it dude -- LIVE YOUR DREAM!
