The T-4 and E are pretty much even - I think the T-4 is built/mounts better; dunno anything about the E2.

 

HMF went down $20? Guys, what ACTUAL hp gains does the T4 give? I decided the T4 over HMF since it was only $20 difference and I *thought* the T4 had better gains. The HMF is dynoed at 2hp. $40 cheaper... hmmm

 

You can't go wrong with yoshi! It is similar to HMF, but it'll give you more mid to top end power and more peak power while the hmf will give you more low to mid range power. As for the headpipe the fmf p.b. gave me a ton of top end, really changed the spectrum, and it made it quieter on the low end while making it louder than hell on the higher end.

 

i have a cobra pipe, it was on the bike when i bought it, and i hate it, don't get one , i would like to get a white bros e series pipe

 

That white bros e-2 is way to costly to me so is the yoshi but thats not saying that there no good because ive never had one but i allways hear diffrent things about the yoshi some say it gives you a good gain and some say they feel like they bent over and took one lol for that much loot it better do something good. I have a HMF it gave me a good gain with a dyno jet kit but didnt do to much with the stock jets but it sounds great not to loud just rite to me plus they look great and seem to be made good.

 

Hey Guys, I am new to this site. From what I have seen so far it is great. I have a FMF megamax on my warrior, with a K&N filter. I have noticeably more power(as far as warriors go) and it not as loud as stock with the spark arrester removed. I also have the quite core removed from the FMF. My wife has a stock warrior with no spark arrestor and the difference between them is quite a bit.
