Woot!!! Just got a flowmaster original 40 S put in!

Find out the size I think I did 2.5 but I cant remember. Check Ebay for mufflers. Find a reputable person on there I got mine for like $80 or so then had a local shop install for $30 Not too bad!

 

I havent noticed a increase in HP or MPG. I got the SUPER 40 Delta series. Only paid 110 or so for it shipped and installed. Thanks to Ebay. They have some great deals on there. Just find a reputable seller. Like I said above. I took mine to a local shop to put it on.

 

so what was the answer to what inlet outlet diameter size ?? i'm going with a round center in center out ,14 in.magnaflow.

 

I think mine was 2.5 in/out. but i am not sure. it was over a year ago already.

 

i've got a FM 40 series, an AR 25 with a AR 25 resonator, and a Magnaflow XL on the shelf.

I'm wondering what the Aero turbine will do for my 4.0. I've heard sound clips, sounds really raspy.
The 40 series should sound pretty good, i remember that about 2k rpms it starts to resonate.

Has anyone put duals before the rear tire?
