What pipe should I get??????????

[chromepowder]

I am just coming to the final stages of building my first trike. Its an 86 250r with a +12 chrome swinger, marvin shaw hillshooter shock, Fully powdercoated and polished everything!!, new esr 370 engine with esr ignition hinson clutch and all the goodies and a 39mm pwk carb. My issue is what pipe to use. The guys at esr thought it was crazy to be putting an engine of that power in a trike to start off with and said that their atc5 pipe would not give the engine the full potential...Will I have to go with an out of frame pipe?? I have seen a few atc's with them and know of a few companies that make out of frame pipes. I have built this to ride in the oregon dunes as I am from canada and would want to take full advantage of the power capabilities of the engine....Thanx Ben

i have a pipe made by a freind at cpi. it fits the r realy good with the 250 motor. but the pipe is a bit to large and only performs on my motor at the very top end. we both think it would work real well on a bigger bore motor. but idk if it would fit your motor? it is still brand new and looks killer but i cant use it for what i want...

my buddie had an FTZ out of frame pipe on his POLONDA ATC 250R! It seemed to work great! From the sounds of this motor I would think it would be ideal for a out of frame. I prefer In frame...Because an out of frame if you for some reason wreck than your forsure going to break, crack, or bend it! For an IN Frame i would recommend a CPI or a PAUL TURNER HIGH REV! Both Top end pipes!

CT pipe

Guys comon, The PTR, ESR and CT all are ment for slightly bult stockish motors they are all going to not perform that motor to the best of its capablities. OOF is going to be the only way to really pull the power right for the motor. The ESR will work with the porting the best (you got the esr cyl go with there pipe)

I have seen a esr pipe on a motor that size before it did just fine, But you dont knwo what your looseing before you go oof.

The CPI we dont really know to much about, I would say if your going Inframe go with the CPI, Or ESR, Your taking a bit more of a chance with the CPI. To really get the right power out of it go out of frame.

thank for all the info guys....who would you recommend for an out of frame then....and wild200x do you want to sell that cpi pipe?

[NOS_350X]

for the cpi pipe contact 3WheelerGod
He works for cpi and it the one that built wild200x's pipe.

I love my PT pipe but with that much mods I think I custom job would give you more for what you need.

[chromepowder]

so who would you guys reccomend for an oof? Shearer, ftz....???

[3wheelergod]

Out of frame is the way to go for all out power. We can get 6-7 more ponies going out of frame than inframe. The inframe would be hard to build without your trike here for me to work on. OUt of frame would be quick and easy to do for you, let me know!

I ran the Paul Turner Hi Rev and it performed quite nicely on the 370. If your not wanting an out of frame I would highly recommand this pipe for your application. If you want the "most" out of it and dont mind the out of frame, spend the money on an out of frame. You can always change your gearing to fit your motor/pipe so dont worry about that. Who made your +12?

Also, if your wanting the most out of your combination, ditch the 39 and get a 41.5

That would leve me to belive, that eather would work, PTR, ESR, or CPI, They are all simular, and work extremely well with built stock ish motors. SO if the ptr worked good i would think the ESR would be jsut as good, Esr is also more known for bigbore bikes, I would think theres would react just as good if not better than the PTR.

Duner, Glad to see you chime in having acutal experience.

Piranaha Pete has dyno tested quite a few inframe pipes on stock/big bore cylinders using LRD's dyno in the past, and he found the PT performed near the top of all testing. Now, this is just one situation, and I am not sure of the random conditions if any, just passing info along. For my combination, the PT has reached its limit, but with the 370 it worked pretty dame good. I would think your comments are right on base. The ESR pipe I believe is a little cheaper too.

btw, you should look at getting a cascade big bore silencer chromepowder if your planning on riding the Oregon dunes. The CSFX and the DM silencers are the only ones that I am aware of that have been proven to pass Oregon sound laws.

ESR just started making new sclincers about 3 months ago, They should have no problem passing now and they are spark arrested..

Nick, Anything without a turn down I would need to see it to believe it. Have not seen one yet to pass on a big bore without a turn down. $175 bones if it does not pass. I would go with a "for sure thing"
