i am wonderin out of the three which pipe is the best hmf, wb e series, fmf titinium 4?

 

I have heard that the wb e-series is crappy(thats what i have heard) i would go with the HMF i know a few people that run that pipe and its awesome...

 

pro crt is a great pipe for the 400ex

 

Sparks X-6! It's the best, and proven.

 

yea tha e series cracks and the fmf pipes rust, heard nothing but good about big gun and curtis sparks

 

Of the three you listed the E-series is the best power gain. That pipe does however crack at the end of the muffler,it hasn't broke yet but is cracked all the way around it. In my group there is 4 of them and 3 are cracked all the same.

If you want the best power gain get the sparks pipe, alot of $$ but worth it.

 

I ordered a HMF for my ex so it better be good.
