Does anyone know, offhand, what the muffler In/Out specs on an '03 Strat SXT Sedan are??

 

i believe it is 2.25 just like the others.

 

thanks for the in/out. i want to get a new muffler put on my car. i've seen people on 2gss.org putting on magnaflows and flowmaster. which one do you think would sound best/give the mest performance for my car??

 

IMO they are about the same. Alot of people on 2gss do have the magnaflow. I personally have the flowmaster 50 series and love the sound almost like the 80's t/a and firebird growl. i have also replaced my resonator with a glass pack to lessen the rasp of the exhaust note.

 

on f-5 performance there is a magnaflow muffler with a 3" offset and says it will fit an '03 strat. how would i measure on my car to see what the real offset is??
