What type of exhaust / muffler are you running?

[GrizzlyMcGhee]

I'm considering putting a muffler on my 4.0L. I don't want anything obnoxious, but I want a little more sound than the stock exhaust... What ya got?

PO installed a Flowtech Raptor muffler on the factory pipe. Sounds pretty decent. Defiantly not changing it anytime soon.

I’ve got a Magnaflow I like. Doesn’t drone at Hwy speeds but sounds good when I get into it off-road. Lots of videos on YouTube with clips of some of the more popular options on a 4.0.

MAGNAFLOW Performance "Off Road Pro Series" Exhaust sounds good and dumps down just behind the passenger seat

Thrush Hush. Very quiet and unassuming.

There's that word...has someone in authority demanded that you change your muffler?

Dynomax. I little bit louder than stock.

 

[Nimbley]

Stock. Anything else sounds like a tractor to me.

I put on an ebay pacesetter cat back on my stroker, it pepped it up and was not expensive, mandrel bent tubing and fit like a glove.

I hollowed out the cat on my old XJ when it started to rattle. It gave the exhaust a hollow tinny sound. Hard to describe but you could hear the empty can. Still passed smog every year though. It was pre OBD so it was tested on the dyno with a sniffer.

Haha, good one, obviously misspelled it and auto correct decided to make me rebellious for the evening lol.

I'm not even gonna edit it.

Ok,now I get that comment.

Magnaflow and 2 1/2" pipe the rest of the way.

I like my walker quietflow a little rumble but pretty quiet, you may find it a little too quiet, I almost do.

Borla "touring" cat-back

Currently have a Dynamax super turbo, very quiet with a nice rumble but cuts back to almost stock over 2k rpm.

It was damaged and I'm debating trying something new or just getting another.

Banks Cat-Back. It's been on my TJ since 2004.
