Default Difference between Rhineharts Dual Xtremes and Classics?

Hi,

Does anyone know what the differences are between these two true dual systems? They are both 4" and the same price. They would be for a '13 RGC.

Thanks

The Extremes exit off the rear header to the right and make it extremely hard to get to your oil dipstick. The classics exit the rear header to the left and are hot as hell on the passengers left foot. Below is a pic of the Extremes. Rather ugly design IMO.

The classics route the rear cyclinder pipe on the left side like the pre 08 models. The Xtreme routes the pipe underneath the frame. The Xtremes are a better performing pipe,but some don't care for the look,and opt for the classics.

I like the xtremes because 1. I think I the x design looks pretty bad *** and 2. It doesn't burn my pass angers ankle. Lol.

The dipstick thing, it's not extremely hard to check the oil, it's still manageable and not as bad as others always say.

Thanks, I definitely prefer the cleaner looks of the classics, but I don't want to give up any performance. I would be doing a stage one with high flow AC and SESPT.

I will add this also since I had the classics on my other bike. The rear header will break. Ask me how I know. And if you look on Rineharts website you won't find a replacement front header. But if your looking for the rear, guess what...they've got that one available. It's a known issue on the classics.

The extreme true duals are equal length headers. The classics are not. You'll get better performance out of the extreme true duals. Not sure how much, but better.

The classics, are just that, the classic look of dual pipes with all of the good things and bad things we know about true duals.

I believe both are a stepped header design.

My 2012 RGC made 80 hp / 100 tq with the Rinehart Extreme TD's, HD heavy breather and PC-V from Fuel Moto with one of their canned maps. I thought this was respectable for a stage 1.
