Does anyone know where I can buy just the collector, preferably stainless? Looking to fabricate a 4-1 exhaust for my CB650. Went to school for metals fab and welding and just got a job in a shop that is cool with personal projects. Fabricating a collector is a bit out of my league for now. Thanks!

http://www.coneeng.com/collector_components.html you need to get the right size to make them work.

4-2-1 is better for the street with better mid range. 4-1 is better for top end and not as good in mid range.

I was going for a 4-1 for the sound. I have a 4-2-1 now. My bike still needs synched 100% its probably at 85% spot on at the moment, I'm not sure if I would even notice the performance difference anyway.

I used http://www.spdexhaust.com/CollectorsB.html when I built my pipes for my CB750 '75Hardtail.

I used a cone collector on my last build but...what they don't tell you is they sell a kit of little steel triangle plates that you have to weld into position to seal up between the pipes. I didn't get the memo on the kit, and had to weld it up from inside the collector, it was a pain in the ass.
