Hi y'all,
My '74 CB750k4 is in great condition, all original, 10k miles and runs fine. Headers are good, but the mufflers are badly rusted out. For me, this bike is a nice looking classic rider, not a concours restoration project.
I'm looking for some input to help me decide what replacement exhaust I should go with. I know many of you have been faced with this decision, and I would love to hear your stories and opinions good or bad. I like the looks and sound of the original 4 pipe scheme, but the cost to replace them is daunting. I also like the look of a 4 into 1 with the right set up, and actually prefer stainless steel.
What I'd really like to find is a 4 into 1, or alternatively a 4 into 2 with paired mufflers, mimicking the original upper/lower theme, I've seen this somewhere, but so far have not found anyone offering what I'm looking for.
Here are a couple options I'm evaluating.
Option 1. 4 into 4 OE style aftermarket. Looks like a choice of David Silver Spares (quality??) @ $1100 + domestic shipping, or one of several Japanese versions - cheapest I've seen is like $1600 + shipping from Japan.
Option 2. 4 into 1. The stainless steel header from Delkevic seems quite nice. Don't really favor their straight or megaphone mufflers though. Considering Delkevic headers and collector + Cone Engineering's 18" "Quiet Core" reverse taper bolt on muffler.
Option 4. Custom (???) setup from a local source (I'm in MN)
I would like the keep the centerstand if possible. I prefer not to have to play with re-jetting.
And I do like a little noise, i.e. low, rumbly, throaty, growly; but not a lot of noise, i.e sharp, blatty, crackly, shrieky.
Anybody care to chime in?
