I got a very good deal on a Magnaflow Muffler in the box part# 12577. I want to install it on my 3.4 tacoma prerunner and have a 12" down tube coming out from the outlet, while utilizing the stock cat and tubes. My question is what kind of sound will this setup sound like? Should I change the outlet tube length?
All I have for performance is a mod air box and a drop in K&N Thax for ur help.

You're going to get a nice tone out of that Magnaflow. Like the person above me said, since the muffler is so large, it will be quiet -- not much louder than stock, but with the added "performance" tone. You'll probably like it, unless you're going for loudness! :waytogo:

The thing I've noticed about magnaflows with my truck is that the larger the muffler the less it will sound rice but the more inside the cabin droning.
If you don't know what droning is, is that humming sound that gets inside your ears and head when crusing...

If you want noise, don't bother with a muffler. Chop the pipe off after the post-cat oxygen sensor and it'll be as loud as it could be due to the lack of a muffler, and also the pipe exiting under the cab.

I have that exact muffler. It's not much louder than stock, except when you step on it - then it screams very melodically. It doesn't sound ricey at all. Has a very subtle but noticeably deeper idle. Does take about 1000 miles to break in (gets a little deeper). It doesn't drone in the cab while cruising. And I can be quiet when I want, but roar when I need to as well. It's how a tacoma should sound. You'll love it.

I guess you won't need the reduceer any more because you went with a 2.25" muffler, huh? Get that thing installed yet? It should be considerably louder than the one you first posted due to the smaller size.
