is there any difference in the bends or anything in the stock form or is the only difference the muffler on the EX having two tips? i have an LX 4 cyl and was wondering if i could be put a stock cat back from an EX on it.

 

As far as I know, they are the same. The only difference between some Accords was the catalytic converter flange on the exit side. Some Accords featured a 2-bolt style flange, while most have the 3-bolt flange. Check this first on your car and the donor car to make sure they are the same.

 

cat back should work. on the ex the o2 sensor is just before the cat.
