"New" 750SS and exhaust question
As I posted in the intro forum, I just picked up an inexpensive, slightly rough '99 750SS/CR that had been made naked by the PO (has all the plastics which I may or may not put back on). Anyway, has about 26k miles, Corbin seat, PC3, pod air filters and was being run with an open exhaust. I'm not quite that socially irresponsible and just won a set of cheap stock cans on ebay to tone it down (have been reading all the coring posts...). But in the meantime while I wait for them, I just threw some stock Sportster muffler take offs (with the baffle plate holed) on it to run around. Actually didn't sound bad, seemed to run well and I kinda like the look. Got me thinking...
Given that this is "only" a 750 (and these mufflers are used on HD 1200's), also given that with the factory pipes each exhaust pulse gets routed to both mufflers, are these really likely to be restrictive to the point of hurting performance? From what I've read about the design of the stock cans, they sound a lot more restrictive than these must be. These are certainly giving some back pressure based on the reduction in the noise, but still...
Any thoughts would be appreciated. Since this bike is a little rough, I'm not all that obsessed with keeping it stock or original or anything like that.
