I bottomed out pretty good the other week and I am pretty sure thats what did it. After my cat, before my mid pipe... so the flange and gasket area leaks... I noticed this the other day when my car was warming up....id say 95% still comes out of end pipe... so 5% leak.. if that makes sense... Is this a big deal? can it wait till summer?

 

Oh, it can wait till summer, believe me. About a third of my exhaust gasses used to come out from under the rear wheelwell, made it fun to pump up tires
Just make sure to fix the problem before inspection, because that would be a complete waste of $20. I say if you have the money for repairs then fix it soon, just so that it doesnt develop into something bigger (such as a big hole)

 

Oh, and how did you bottom out? I've only done it once, we have like 6" of clearance.

 

I lowered my car . I live in Alberta Canada, and we have some **** roads.

 

it can definitely wait. I noticed min in novemeber of last year and just fixed it today. Overall it does nothing except being annoying in terms of sound, although depending on the location it could vent exhaust fumes into your car...mine did and it wasn't particularly pleasant...
