White Bros. E-series/ R-4 Series, Whats the diff?
Maybe some of you rapptor guys can help me out? Whats the difference between these two systems? I'm gonna soon get one of the two, and want to know any power advantages/differences between the two. I had seen one of the gentlemen on here that had one of the R-4's for his raptor, and I know ALOT of you guys have the E-series on your raptors. As always thanks for all responses.

The E series is adjustable using the discs. The R series is similar to the GYTR, Big Gun and other straight through pipes. I have the R4 and I love it. I got good power increase and it sounds good. I've never tried any other so I can't compare, but everyone has their opinion on what is best.

The E series has the disk type spark arrestor and, the R has the screen. I think the R looks better because it is polished and, the E is dull. I also like the sound better out of the R and, the way it looks when the cylinder fires and, you see the exhaust puff the dirt or sand behind the bike,, which you won't get w/ the disk type.
