My exhaust is really loud all the sudden, and seems to pop on decel. It sounds "aggressive" but is ear ringing loud especially around 4,500-5000rpm. I had my rear tire changed today, and the exhaust change happened after that so I'm assuming the exhaust may have been loosened to fit the tire. Is this something I can fix with handheld tools, or will I need to stop at a shop? Would I just loosen a few bolts at the slipon and apply some high-temp sealant, and throw it back on, or is there more to it than that. Other than the sound/decel pop, is this something I need to worry about, or is it just an annoyance. I have another 6,000 miles or so left to go, so I don't want to cause damage. I've heard it can cause a lean condition, which I would assume could possibly foul the spark plugs.
Thanks for your help.
EDIT: Asked in the general forum since I'd assume I may get a fairly quick answer, and it's not particularly model-specific, it's one of those "general" type questions. I apologize if this should only be posted to the 12/13GT forums.
