That Marshall racing baffle probably sounds similar to some of the cafe racers we've heard here.
Like the 550 at Benjies. Lots of clatter from each individual cylinder but if you could deal with noise I'm sure the performance is well worth the decibels !
I'd like to find out what type of horsepower numbers one would realize between the two.
The same company Laser makes a slip on muffler for the 550 as well but from what Ive seen it's about $220.
Too bad that Kerker doesnt make headers/exhaust for the 550's any longer.
Someone commented that $450. is alot to pay for an exhaust which it is. Part of that is the weak dollar for In pound sterling it's only 199. !

You see the guys on OCC fab up all of their exhausts from steel tubing using the pipe bender. Makes me wonder what a good bike shop would charge to fab one up ala a Kerker for our CB550's especially if you could use the stock header as a template for the tube lengths ?
It might be another option/consideration.
Anyone know of any shops that would ?
