Flowmaster 40's

I have mine from catback. Did you buy the 40 Series standard? Look at the Flowmaster website for the descriptions of sound for each. The standard is the most aggressive sounding.

yeah i got them from a friend for 50 bucks.. He had to sale his car and didnt want them to go. He is buying a new truck and plans to get another exhaust system installed. The mufflers are less than a year old so i think i got a good deal.

Do you have any suggestions for installing the two mufflers? should i just run a pipe from the cat, then add a y pipe to each muffler or what??
