flowmaster original 40

im planning on installing a flowmaster original 40 muffler into my 06 taco ive heard they are the most agressive sounding and thats what i want i have the TRD on there right now and i hate it the thing sounds almost stock i would like to know what muffler offset i should buy ,size of pipe (i think its 2.5") and if i will be needing any other pipe or material to do this. some pictures of some setups with this muffler would be nice to so i have somthing to reference from while im fabing this ive looked but havnt found much thanks -nick-

 

I'm running a Flowmaster Super 44. Its the most aggressive muffler FM makes...it sounds mean as hell!!!!!! Real deep tone and that throaty growl you'll want!!

 

just put on the flowmaster 40 and it sounds nice deep and throaty it really makes your 4.0l sound beefy i highly recommend it for anyone just going for sound

 

what diameter? and is it offset inlet center outlet or what?
