ya i am just wondering which is better for the track, A white brothers e2 pipe or just the white brothers e series
the e2 is a $100 more so is it really worth it??

 

my buddy has the e 2 its to high in price. i would tri the hmf i have one on my z and love it

 

ya i hear ya on the price but i am leaning toward the yoshimura pipe now, just the slip on...
I have heard some good stuff about it.

 

my friend's got a e series on his 440ex..... it blows monkey nuts. I got the R4 on my raptor and it is great.... its loud, but the sound is really great, and it aded at least 8 horsies to my rappy, i will say that white brothers knows what they are doing when it comes to 4 strokers. i got the R4 slip on for like 220 bucks on magicracing.com
