Let me preface this by saying, i am not overly inclined, mechanically so this may sound like a dumb question but here goes.. if i have an exhaust leak back closer to the end of the exhaust system, specifically by the muffler/pre-muffler, how bad is it? for context, on my 2014 zx6r i recently replaced the stock muffler with an aftermarket slip on. after getting everything installed i noticed the most minimal (and i mean MINIMAL, i dk that i can overstate this lol) pinhole exhaust leak where the new mid pipe slips into the pre-muffler section of the exhaust. the exact location of the leak seems to be on the pre-muffler, RIGHT below the clamp that holds the mid-pipe in place, in one of the pre exhisting slits in the pre-muffler. given the fact that it was so faint that i had to hold paper over it to even confirm that what i felt with my hand, was an exhaust leak, how important/necessary is it to fix/seal this? i don't know if this is a "if it doesnt bother you it doesnt matter"..or a "if you dont fix it something bad will happen or get worse". the most common theme seems to that an exhaust leak could equate to a loss of power(among other things). if there is, i don't notice it and i guess i'm just wondering if it's far enough back in the exhaust system that it truly wouldn't even matter/make a difference. it's a 2014 but i got it with next to no mileage on it at the start of this year. there's barely 2k on the gauge so as far as i'm concerned it's a new bike and i want to keep things in good working order, but if this is more of a preference thing over a necessity thing, i don't feel the need to fix it. Thanks in advance for the input!
