Need Help to change Muffler

[sobri46]

thank you for your reply,


i think you are right that may be the exhaust pipe of my 1300 cc yaris will be less than 1.75 inch and may be it will be only 1.5 inch
if i will just cut the oem muffler, then make an adapter from 1.5 inch to 2.5 inch and add 2.5 inch pipe about 10 inch only to fit the long of the pipe after remove the old muffler and then put the new 2.5 inch muffler
with out changing any other OEM pipe or resonator or header .
do this modify will be good and will not changing the power of the car ?
i just want to get a good sound and not looking for increasing of more power or HP for the car.


the problem is i don't find any good 2 inch muffler on ebay .


please help me to resolve this matter


thank you
