I have always beena fan of dual exhausts. I want to put a dual muffler system on my quad. My question is can i make a custom exhaust on this? They dont use a special metal to do that do they? the bike is a 08 400ex. I have flanges for it, just need to know if this is possible??

I have seen it done before but very ghetto.

 

Just make a 2-1 collector from two 30* bends and use it the other way around.

 

It has two pipes that come off it. They go into one. What kind of metal should i use, i guess thats my main question. Do i have to use a special thickness and what not on these bikes???

 

400EX: Front Tube left, and right are 1.25" SS-304 0.065. The collector is dual in 1.25" collected to single 1.75". You would probably want to build a x pipe, dual 1.25" in, dual 1.25" out, cross-over your flows and run them into dual mufflers. Material is regular 304 stainless or mild ceramic coated.

 

Holy ****.. Thank you....

You done this before????

 

Not our designs, just contract manufactured assemblies for quad companies.

 

Any interest in selling these to the general public without a name/brand on them?

 

No, that would unethical.

 

Yes. Definitely don't try to build a true dual exhaust. You will lose power if you don't collect the exhaust to one pipe before the two mufflers.
