Bassani Exhaust ?

[rely]

Who can tell me the difference between Bassani B4 and the Road Rage 3, they look the same and I don't see any info on there website, thanks in advance.

bassani has some mysterious nomenclature. I've got the b-1 for my softail, not to be confused with the b-1 for baggers. Apparently different size header pipes and collector.

Their website leaves a lot to be desired.

I can't really help you with the differences as I use the D&D Boarzilla but my buddy likes his bassani 2into1 exhaust.

In my past experience Bassani is not an easy company to get information out of, however I loved my original Road Rage pipe.

I'm going to ASSuME your are asking about a touring bike pipe. It looks like both pipes are the same headpipe. Both 1 3/4 to 1 7/8 stepped. I think the only difference is the B3 is a shorter muffler body. It doesn't appear to extend beyond the saddle bag in the pics I can find. The B4 pipe appears to extend beyond the bag.
