I have a question about headers. I am going to buy a pro circuit t-4 slip on now for my 400ex. I was wondering if any other brand header would line up with my t-4? I know that the fmf factory-4, wb e-series, and pro circuit t-4 are all slip ons where you can add a header later on. Its just I don't want to spend $300 dollars on the pro circuit header when I can get one from fmf or wb for around $180. any tips or suggestions are welcome.

 

the only headers that will fit slip on silencers are the pro circuit and the fmf power bomb. i know the white brothers header WON'T fit slip on silencers.

 

have you had any personal experience with the two of these?

 

sorry, i only run sparks pipes. the WB header is just bigger than the stock header so the two wont go together. i talk to many people who do like the powerbomb header, but i guess they really don't have anything to compare it too as far as the power output. i would probably get the one you can find the best deal on. i have a feeling your not going to notice much if any power gain anyways.

 

I know about the power already. What I am looking for is something that will come clean. The stock header has clay and mud cooked onto it. I figured if I could find a nice chrome header for cheap, it would look nice because I could clean it with CLR. thanks
