What would cause sputtering sound during acceleration

I have been trying to trouble shoot why my taco sputters, almost small backfires about three times when i mash the gas, i thought it would just be a clogged fuel filter, but changed it and it isn't. So after looking at my exhaust the other day i noticed that the weld on the in pipe to my muffler was rusted through so there is about a 1 inch by 3 inch opening at the front of my muffler. My truck is trd supercharged so would this hole in the exhaust be the problem with not letting the back pressure build up when the truck downshifts and causes the backfiring?

 

I was about to say you probably have a hole in your exhaust system but then you confirmed you do. This is probably the cause of the sound. Your just hearing the exhaust leak, most likely.

 

alright well that just mean i need to save money for headers and redo the whole exhaust lol

 

haha, or just get a shop to weld up that hole till you can get some new pipes

 

i could, or convince myself that i need all new exhaust haha. Plus it makes me buy headers faster which i have been wanting lol

 

haha do it! and get me some too

 

or...you can part out the truck and give me the super charger

 

hmm tempting, it really is lol
