Long arm muffler

[napajeep]

OK, I've got the long arms on the rear, now looking for a muffler. I've got a 3" converter and 3" tailpipe. For those of you that have heard these mufflers, which is the quietest inside (resonance)?

Dynomax Bullet
Moroso Spiral
Magnaflow round

All are round mufflers, but I'm looking for something fairly quiet.

Thanks.

i dont know about the other two byt the magna's round mufflers are LOUD on mustangs

[BigDaveZJ]

I've got a MagnaFlow 14" oval body on mine, pretty loud. Pam has the 16" oval on hers and it's a little tamer. You can fit oval mufflers with long arms, just need a good exhaust shop.

Bullets are loud, same with the Mangaflow.

I have a magnaflow cat and 14" Magnaflow oval and it is pretty loud, not a whole lot quieter than just the factory cat just sounds a little better.

I have a magnaflow oval, 14" Much quieter than my brothers flow 40, MUCH quieter.

i'm running this - sounds a little throaty when new (with my 4.0), but definitely mellowing with age - i like the sound now - installed this time last year

got it here: http://www.performancepeddler.com/ - found him on ebay - he had the best price i could find at the time - i've bought a few things from him since - great to deal with - super fast shipping

Yeah, I was looking at the Hushpower, but they don't make it in 3". If I were running smaller diameter pipe, I would have gotten that one.

Any one ever hear a Dynomax Ultra Flow? They make that in a 4" round, 18" long version.

honestly, I think it would be harder to fit a longer muffler it there than a wider one, at least that is true with my clayton's.

My turndown is just about even with the rear LCA brackets. The exhaust shop that did my exhaust for me used the rear LCA brackets to run a tab over to the turndown as well to help stabilize everything. My cat sits on the top of the x-member.

I have the RE long arms, not triangulated like Claytons. The upper arm goes straight back, thus leaving plenty of room length wise (if it is small diameter). I could fit an oval muffler if it were short enough, but anything that short is liable to be extremely loud. I am still going to go over the rear axle with a tailpipe which should keep it relatively quiet inside. Thanks for the imput though.

Sounds great on the 4.0L. I'll be putting one on my Toyota eventually.

I ran mine over the axle and out the side.

I bought and installed a Moroso Spiral. It's certainly not a quiet muffler by any means. Sounds good though.

I am using a Summit Racing muffler on my Jeep. It's not "road legal" according to Summit, but it was either that muffler or nothing at all with the way I set it up. Plus it was cheap. No sense on spending lots of money on a muffler.

It's fairly loud compared to stock, but nothing crazy. It doesn't attract attention when I drive it on the street, so that works for me.

Here is a 3" one.

I just have a turn down welded onto the back of it and it hangs over the end of my belly pan.

i've got the same problem with space and a muffler does the hush power really sound good. i like em low. i have the 4.0 and wanted the small muffler.

[DJJordache]

I have a magnaflow (that is all they had at the muffler shop that would fit) it is a normal center in and offset out oval muffler and I got it to fit tight fit but it is in there with Claytons. I have my cat pushed as far forward as it will go and it is turned a little to sit partially above the rear of the crossmember. I'll see if I can get pics this weekend.

[dangerousdave]

I went with a muffler like this.

I fit it in with a stock converter after alittle bit of work and triming. This is not the muffler i used I cant remember the inlet and outlet measurements. but it is just like this one and the price was the same. about $22... $32 to the door. and they are on top of there shipping department.

[wheelinzj93]

well how does the glass pak sound on the 4.0. is it low or throaty sounding

[ILikeMud]

It's loud and sounds like a tractor.

[napajeep]

I wound up running two mufflers. I have a bullet up front (right behind the converter) and a Moroso spiral flow that I'm using as a resonator. It looks like ass, but sounds good.

[dangerousdave]

Its not much quieter than having nothing at all. But I like it. it did deepen the tone of the jeep some. It just gets me through inspection.

[Sudz]

run a hushpower - you'll be thanking me later

just took these:
