Opinions needed?

Im curious, will a newer metric muffler made for like a gsxr 600, or cbr 600, or r6, or zx6r, or something similar have close egnough backpressure for an 82 kz550?

I know jetting might be neccisary, i got the stock air box set up and 4-1 header, but i want to attach a newer tailpipe to the header cause my old baffle is pretty much shot.

What worked for you 550 riders?

Thanks much

Luke

If interested, new replacement baffles are available for Kerker and Vance & Hines, and probably other 4>1 exhaust system mufflers.

Good Luck!
