Pro Circuit T4 vs. WB R4

[tryken]

Does anyone have any input on which of these two is the best system. I plan on getting a complete exhaust system in a month or two and am leaning towards one of these two. Any input is greatly appreciated.

the wb has a larger header than the t4 so i would imagine it will help up top more, i belive the r4 produces more power everywhere

[tryken]

If I end up getting one of these should I get the complete system, or some other type of headpipe?

[YZROOSTINYA]

if youur gonna get the t4 get the whole system

i wouldnt suggest a whole system with the r4 on a stock motor

How would either of those silencers be with a FMF powerbomb header. My motor is bone stock except for my listed mods in my sig. I do plan on getting a k & n filter and dyno jet jet kit prior to getting a new exhaust system.

The R4 works well with a powerbomb from what I'm told. The only downside is that the powerbomb makes it a little quieter.

I love my PC T-4 slip-on. It made big improvments in power in the low-mid range. It sounds great, has 3 different endcaps to tune your power, and its relativly cheap. Its IMO one of the better 400EX slip-ons.
As far as a different headpipe goes, I really wouldn't change it until you have done some internal motor mods, but if you do go with the powerbomb header by FMF. If you go with too big a headpipe you lose bottem end power. The powerbomb header w/ the PC T-4 silencer is an excellent exhaust system in the end.

the slip ons are the exact same, one is polished, one is not. also, they have different spark arresters. the wb header is bigger though.

i have a r4 and i love it it gives you power everywere its a little loud but worth it i have the stock header with the grinds welded out and it works great with the stock motor but in the spring i plan on gettting a lrd 440 kit then ill up grade headers to the wb header
