hi, i am new to these auto mechnics stuff. all i've done so far on cars are changing oils, filters, plugs, bulbs, and polished those yellowed out headlight covers. n that all happened within the last month after i helped my friend fixed up a 97 civic and started playing around with stuff on my 92 camry i4. anyway, i just ordered the clear bumper lights and a new air intake after reading some of the threads, and I am thinking about getting a new muffler to the stock exhaust pipe, more or less just for the heck of having fun. i am looking at all the universal muffler and they all have the inlet pipe in the end of the muffler but if i am not wrong, the exhaust pipe goes sideway into the stock muffler. so what size in length of the muffler do i need for a max fit or do I have to weld an elbow to get the exhaust pipe into the inlet? n i haven't been able to find this else where but what is the exhaust pipe of a stock 92 5sfe, 2 1/4" or 2 1/2"?
