Al Evitts Posted December 28, 2009 Share Posted December 28, 2009 What is the concensus favorite muffler for the 4.0 engine. No drone but a good crisp sound \ Thanks Al Link to comment Share on other sites More sharing options...
Eagle Posted December 28, 2009 Share Posted December 28, 2009 I doubt there is a consensus. Personally, because I plan to keep my XJs and MJs for a long time, I buy the Auto Zone store brand with the lifetime warranty. That way, I only buy one muffler per truck -- ever.

freakjeep93 Posted December 28, 2009 Share Posted December 28, 2009 i know some people used flowmaster super 40s . i while never using one on a 4.0 like cherry bomb turbos or glasspacks there is many opinions Link to comment Share on other sites More sharing options...
89eliminator Posted December 28, 2009 Share Posted December 28, 2009 I doubt there is a consensus i agree. its like asking what tire is the best. i run a Flowmaster 40 on my 89. i love the sound. its loud, but not too loud. Link to comment Share on other sites More sharing options...

socal1200r Posted December 28, 2009 Share Posted December 28, 2009 I used one of these chambered, all-welded mufflers from Thrush on my 4-cyl MJ: http://www.summitracing.com/parts/WLK-1 ... mage=large I highly recommend using one of these mufflers from Thrush or Summit. I've used them with great results, and they're considerably less expensive than something from Flowmaster, Magnaflow, etc. Link to comment Share on other sites More sharing options...
Darren Posted December 29, 2009 Share Posted December 29, 2009 I vote glasspack. Link to comment Share on other sites More sharing options...
Automan2164 Posted December 29, 2009 Share Posted December 29, 2009 Flowmaster 40... Had one on the Eliminator, have one on the ZJ 4.0L... Sounds great at idle, a few people have thought I have the V-8 because of it... Sounds ricey at high RPM's, but you are pushing 6 cylinders through one muffler, so its going to no matter what ya put on. Rob L. Link to comment Share on other sites More sharing options...
socal1200r Posted December 29, 2009 Share Posted December 29, 2009 Flowmaster and Magnaflow mufflers are about $70 from Summit. Thrush is $30, and a glasspack is about $25. For the money, I went with the 2.25" inlet/outlet, chambered, all-welded Thrush, for less than $40 delivered. But a lot of the auto parts stores carry these mufflers, and you might save a little on shipping if you bought one locally. Link to comment Share on other sites More sharing options...

ComancheKid45 Posted December 29, 2009 Share Posted December 29, 2009 I run Flowtech Raptors on both my Jeeps...about $30 shipped from summit, just enough sound to let ya know its there but not overly loud at all. Link to comment Share on other sites More sharing options...

500 MJ Posted December 29, 2009 Share Posted December 29, 2009 Flowmaster 40 series on both Renix setups here. Won't run anything but them now. Link to comment Share on other sites More sharing options...
streetjeep2.5 Posted December 29, 2009 Share Posted December 29, 2009 Don't remember what number, but a flowmaster single in/dual out on my 2.5. Been on now for 6 years. Sounds the same as when first put on. No ricy sound, I think because of the dual out. BTW, I have turn down tips coming straight back out under the bumper, and resonating off the pavement adds to a "throaty" idle sound. Link to comment Share on other sites More sharing options...
jeepdoggydogB Posted December 30, 2009 Share Posted December 30, 2009 I have used Walker products for a long time for OEM sound, and they are usually cheap. http://cgi.ebay.com/ebaymotors/ws/eBayI ... MEWAX%3AIT Link to comment Share on other sites More sharing options...
streetjeep2.5 Posted December 30, 2009 Share Posted December 30, 2009 Haven't looked at Walker for a while, but when I bought an 85 Chev Cavalier at 65,000 miles, I bought a lifetime Walker and as long as I owned the car (over 200,000 miles) never had to pay for a muffler again!

I picked up one of these from the local hot rod shop after work last night.......I'm definately impressed with it and I haven't even gotten it on yet (maybe tonight after work). Dual chamber, all welded...the thing weighs at least 5 lbs :eek: Image Not Found Image Not Found Image Not Found will be replacing the current glasspack.....it's cool and all, but has become a bit annoying, plus it doesn't have a spark arrestor Image Not Found Image Not Found Link to comment Share on other sites More sharing options...
socal1200r Posted December 30, 2009 Share Posted December 30, 2009 ...I picked up one of these from the local hot rod shop after work last night.......I'm definately impressed with it and I haven't even gotten it on yet (maybe tonight after work). Dual chamber, all welded...the thing weighs at least 5 lbs That looks like the exact same muffler I'm running on my MJ now. Got it for less than $40 at a local auto parts store, which is actually a little less from Summit, since they're like $30 at Summit plus shipping. I like how it sounds, and the design/construction is VERY similar to the more expensive mufflers from FLowmaster and Magnaflow. It's funny, because on Summit's website, I think that Thrush muffler is made by Walker, because it has a Walker part number. Could be that a lot of the brand mufflers are made by just a few companies, and just rebranded, like they do with athletic shoes and such, lol...

kro10000 Posted January 2, 2010 Share Posted January 2, 2010 My Mj has a flowmaster 40 with no cat and sounds great, my bro has a super 44 on his 4.7 stroker TJ and it sounds pretty close, just louder. Has anyone tried a hooker aerochamber on a jeep? Link to comment Share on other sites More sharing options...
Al Evitts Posted January 21, 2010 Author Share Posted January 21, 2010 Got the Hush Thrush on today. Has a little throaty sound but no drone. I can now hear the radio. Thanks for the info. Al Link to comment Share on other sites More sharing options...
mule13 Posted January 21, 2010 Share Posted January 21, 2010 You should buy a header and just run straight 4" pipes from it out the back. when your in low range and really rapping out the engine it really draws attention ;) just kidding i have the generic brand flowmaster on mine Link to comment Share on other sites More sharing options...
