[highstage]

Whats a straight pipe?

 

[maxwell]

sounds like a terrible idea. unless by straight pipe you mean really loud can...

 

[highstage]

a stright pipe is no muffler just pipe its loud and sounds good my conceren is there is no back press on them like a can i have one on my 800 ho and it has been fine but will these new 800 be ok

How much weight did you have to take out of your clutch when you put it on? That thing would lose a bunch of HP, and i'm suprised you didn't burn the engine down in 5 seconds.

x2 on the meltdown! years ago we used to make stingers and had to weld washers on the end to make the right back pressure! but that was also tested and tuned on the dyno!

straightpipe hmmmmm.... is the pipe actually straight? can u do this to my sled too?

dont grease the muffler bearings that will help with the noise

How has this thread gone on this long? Heres how it should have went...
Post 1. Can I straight pipe my sled?
Post 2. No, It is not a camaro.

Yah you bet you can straight pipe it if: you want less HP, good chance of doing engine damage, cause extreme noise that can trigger avalanches. Dont need to continue.

You won't see any results from a straight pipe unless you compliment the mod with a minimum of three monster stickers.

The expansion chamber is part of the pipe...not the can. Most of the new motors have internal stingers inside the pipe....so the can is only a muffler and the only tuning factor it provides is outlet diameter or "effective" outlet diameter. Diameter of the outlet is VERY touchy on a 2-stroke....one (1) mm too tight at too low an elevation = melt down.

Edit: and to the original poster: don't be silly.

yes you can straight pipe it. just remove the muffler and weld on a piece of piping like you did on your ZX. everybody is afraid to do it and thinks it will blow a motor lol yet they buy mbrp cans for $230 and all it is is a hollow pipe with some packing around it. you can see right through those suckers so instead of paying $230 for a striaght pipe i bought a 2' section of 1 3/4" pipe and made my own on my m1000. sounds sweet runs mint and weighs like 20lbs less than it did before. cost me $5 and about 2 hours to do. The expansion chamber is what makes the correct amount of backpressure in a two stroke engine. the exhaust canister or "can" is what muffles the noise. people think the can keeps backpressure but they are wrong. google it. i did. i read up on this many times before i did it to my sled in fear of a lean burn down like everyone guesses will happen. As for power loss, its no different than a mbrp, probably loses 3 horsepower and 20 pounds give or take but sounds sweet as well.

Everything you search on google is true! If you don't believe me, just search it!
