I took the exhaust system off of my CB750 (4 into 2) and much to my surprise, the head pipes are separate from the mufflers. The mufflers I have now come straight out, and I would like a set that comes back and up a little bit. About as much as the stock 4into4 does. Anyways, I was wondering if anybody knows of a 2 into 1 muffler (both sides) that is available? I tried ebay, but didn't get any decent results. Below is a pic of basically the same thing as Ive got (different muffler design). Thanks.
