Muffler

[tjkj2002]

I beg to differ. Mine's quite loud. Mainly tire roar but loud none-the-less.

Must be a newer KJ thing as mine has great sound damping.

When I was home a few years ago my Sister and her husband passed me on the interstate.I was doing 65mph(3000rpm's) and they said my KJ was so loud it was shaking there minivan.Took my brother in law for a ride at 65mph and he was amazed at how quiet it was inside till I rolled down the windows.

I lucked out and found a discounted Borla kit. Sounded good, little louder but not obnoxious.

I like the start up and idle sound of those but revving sounds like a tin can

Go to 3:53 and you'll hear what I mean
Then again, videos don't do sound or light justice so it could just be the guys mic but it sure sounds like there's a tin can on the end of that tailpipe

I wonder if this KJ is the 4 cylinder? Mine sounded nothing like that lol. Mine was a nice deep growl. Even in the higher RPM's!

Had there dual exhaust cat-back system till I crushed the muffler on the trail.Damn thing is bigger then the OE muffler.Sounded good but not for offroading.

A 40 series flowmaster with a resonator probably. They have the best muffler construction hands down. Next would be that one stainless catback you see around or Borla with resonator. You have three cats so it'll probably never bee too high db. HKS might have a catback.

To me it sounds like every other V6 without a resonator which it kind of is since it's basically a generic Mopar engine design without special stroke or valves.

Does anyone have a MBRP exhaust, I ask because I have a brand new MBRP exhaust systems sitting in the box in my attic.

This was the single muffler, same length but a little wider muffler, it bolted in like a stock replacement kit.

And how does it sound up there?:gr_grin:

Dam it put that thing on!

No I do not have one, but if I had one in my attic, it wouldn't be in the attic

got the magnaflow # 13256 today , bolted it on and sounds great. Having it welded tomorow though because the fit isnt very tight and welded holds better obviously

I'm going with the FM Super 44.. aggressive sound with low drone (I have music on a lot anyhow so no worries there)
Also because I found a hell of a deal including the muffler, new tail pipe, exhaust tip, and clamps all for under $200
I'll also be getting some black high heat paint to paint everything to one solid color and make it all look good
I plan on getting it all probably next week or so, so I'll keep updating my progress once I decide to buy it all!

Here's mine when I first installed it. It's a little richer sounding now.

Sounds great
Which model did you go with?

MBRP cat back aluminized steel

Well, I went with the Super 44 and it sounds GREAT
Loud outside but the drone actually isn't too bad
The drone is slightly loud when cruising down the highway but around town it's pretty quiet- when you let off the gas it's like it isn't even there especially since I always have music on

I've had it on for only two days so far so it'll take some getting used to but it was well worth it
I purchased the Super 44, exhaust tip, new tailpipe, extension and clamps all for under $200
Except, I paid for two day shipping for the tailpipe from Walker on the 24th and it's still not here so I'll be getting my money back for that

Anyway,

I would like to hear a sound clip of what ever you choose.

Here you go!
Go forward to 0:51 to hear no muffler start up and then to 1:37 for the Super 44
