Muffler

I plan on having my brother get me a muffler for christmas...a Flowmaster Super 44. Im only replacing the muffler, and my question is what diameter piping do I need and do I need center in/our or something offset. Anyone know?

I would say check the FAQ's potion of this forum and see what size piping you have on your 4.0 already...then go from there.

2.25" is the pipe size, get underneath your Jeep and look what you have for offsets right now

Well Im in school now, Ill check it when I get home

If I just get a turndown after the muffler, would that make it louder while still being legal?

it will make more interior noise and also could allow the exhaust to seep into the vehicle itself. So I hear.

yes, your 4.0 came w/ 2.25" piping. remember 2.5" is the optimal exhaust size for you. so if your putting in a turndown you can just go w/ 2.5" with a 2.25-2.5" adapter, and you can just get center inlet/outlet because it doesnt matter w/ a turndown.

when i first start up my car and more so when its cold, i seem to smell a little gas, idk if thats b/c of the turndowmn

Yea, you'll get more interior noise with the turndown. Especially around 1500-2000 rpm. My 50 series sounds decent with the turndown and I haven't had a problem with gases getting inside the car. A turndown is nice cause is cheap to put on and you don't have to worry about keeping a nice tip clean and polished.

Just FYI, heres a video with my 50 series on my 4.0. I think it sounds better now than in the video cause its had time to "break in".
