i have a 2000 monte carlo ss 3.8 I am goin to put a flowmaster muffler on it and i was needing to know if i have to have 1 or 2 mufflers and the diameter of them...i thinking its 2 1/4 but im not positive....if anyone can help it would be greatly appreciated

 

well my cd goes up to 99, there's 2 mufflers and they're 2", i dont know how hot these would look at the back of the car..your further ahead to put one muffler near the middle and 2 tail pipes

 

ALRIGHT THANKS.....JUST NEED A LIL MORE INFO

 

i need to know the inlet and outlet diameter on the exhaust on my 2000 monte carlo ss so i know what muffler to order

 

to my knowledge it is the same as my Z

2.25 all the way back. and yes you have two muff's if you got the SS
personally i would look here for ideas and info for exhaust first: http://milzymotorsports.com/
