Well, I am relatively new to the 4runner game. i just bought my 1997 SR5 5-speed 3.4l v6 4wd about a month ago, and now I am looking to start putting money into it, mainly exhaust first for now. I think I found somewhere that the stock piping size is around 2.25 inches...? My friend has a brand new flowmaster 40 series with 2.25 inches in and out that hasn't been out of the box yet. Would this work on my 4runner? I would like to make it work considering hes offering it to me for 50 bucks. Thanks for your input, I appreciate it.

 

Thats a steal - do it!

 

it will work, and 50 bucks is pretty good... its only like 69 bucks brand new. but yeah. hop on it.

 

as long as it's center/offset 2.25 you're good to go man..

 

It works, I run that same muffler on my 1997 4cyl

 

It will be really LOUD with the 3.4 but if that's what your after then yes, any muffler shop can weld it in.

 

The 40 series is going to be way loud

 

I just recently put the 50 series and even that is loud. I called flowmaster directly and they adviced against the 40 series

 

I agree a 40 series will be really loud and drony, esspecially on an automatic as it is almost always between 1800-2200 rpms durring light throttle and cruising, which is where it drones the most. I just installed a 22" Magnaflow and it sounds great, a little louder than stock with a nice deep tone.

BTW, 2.25" is smaller than the stock exhaust, it is 2 3/8" from the factory, 2.5" would be better.

 

BIC, do you know what the P/N for that 22" magnaflow was? Was it #12577?

 

i dont like the sound of a flowmaster my 18'' magnaflow is great

 

im running one and chopped my exhaust pipe just above the axle, sounds GREAT.. ill put a vid up later
my only thing is my mpgs have dropped.. not because of the flowmaster.. it just sounds so good ive been driving around revving it at a higher rpm than i should

 

VSU - thats hilarious, sounds like something ill be doing soon once i get my exhaust on my 4runner...
off topic but thats tight ur in a frat (im a sigep myself)

 

I had the offroad super 40 series muffler on my 4runner for about a year. Lets just say that because of the noise, I am now running a 24" magnaflow and loving it! can that 40 series idea. You are going to like it at first, but then you make a 3 hour trip on the highway a few times and that stupid droaning noise with drive you crazy!

 

I am trying to order the flowmaster 50 cause I travel on the highway sometimes and I have a 2000 4runner. Real quick, is the muffler supposed to be center in/ offset out? I know it's 2.25.

 

Yes, read the thread next time.
