header compatability

[bmf400ex]

i was thinking about putting an FMF powerbomb header on with my T-4. will it fit, if it does is there any gain or losses over stock. Or should i just buy the T-4 header. i'm not a big fan of pro-circuit.

i believe oynot400 has this same exact setup and likes it alot.

Yes I do have that set up, and I do like it alot! :D The powerbomb will quiet the T-4 down a bit, but it still has a good throaty sound. The only thing I do not like about it is the connection between the head pipe and silencer. The head pipe is a little bit smaller so it doesn't get a real good seal and it will wear out the o-ring quickly. I have heard that if you get a gasket for that connection out of a stock muffler it will cure the problem. I have the gasket bought but I am waiting to install it when I put the motor back in. :)
You will like this set up. :D

Use the gasket from your stock muffler to get a good seal.. welcome to the powerbong club..:devil

any more power increase?????????? I am also putting in a 440 kit will the header help?

I am sure that there is some power gains, but I can't say how much. When I put mine on I also added my FCR. So between the two it was a conciderable amount. :)
