This muffler fits the size requirement and price requirement I need. It will be behind the skid plate so toughness not an issue.

I want it to be quiet!!!!! Anyone run one of these? 4.0l engine

It is a welded muffler, it will not be quiet.It's a Flowmaster 40 copy, really. And it's not that great quality, either.

cisco · 02-09-2011, 12:17 PM

Okay ... you say its a welded muffler and that is going to make it nor as quiet. can you explain this?

pcoplin · 02-09-2011, 03:54 PM

It's a chambered construction, no packing. Only steel baffles. LOUD.

Magnaflow. I have one on a 4.2 with 4.0 head and it isn't that loud. Doesn't even sound that bad on the I6. Flowmasters sound like shit.

Dynomax super turbo, they are nice and quiet, flow good, and are reasonably priced. I have one on my YJ and it's good.

It says Thrush on it, that should be enough to know that its loud.

I have this thrush muffler http://www.summitracing.com/parts/WLK-17713/ on my rig and its pretty quiet. But then again my 4.0 has 3 cats before the muffler......

jpnjim · 02-09-2011, 07:02 PM

The Thrush in the original post is a Chinese Flowmaster copy.

I bought one 3-4 years ago, and the tubing size was way off.
It was supposed to be 2.5"ID, I'd say it was 2 5/8" ID, or more.

cliff notes:
It's loud like a first gen FM, it's cheap, made in China, and sometimes they screw up the tubing sizes.

WTF? Why?

Warno · 02-10-2011, 04:19 AM

i just put a 40 series flowmaster on my jeep with on cat. it's loud. i would suggest you look into like a 80 series or a hush power (i think it's called) from flowmaster.

white_elephant · 02-10-2011, 05:45 AM

Borla ftw...

faziom · 02-10-2011, 06:42 AM

I took off flow masters and installed a single hush its much nicer... $130 bucks, but ceramic coated and a lot quiter.

Commyfornia........I swapped a 4.0 out of an 01 xj into my cj-8. The 4.0 has 2 pre cats just south of the manifold, it y'stogether into the main cat.

I have a Hushflow or whatever its called on my YJ 4.0. Has just enough sound to know the motor is running right but not so loud you can't hear the radio turned down at an idle. At highway speeds the tire noise completely covers any exhaust noise what so ever. Hope this helps I'm not one for loud exhaust personally.
