i_be_heepin I have a super 44 on my jeep and what made a huge difference was cutting the tail pipe a little ways behind the rear bumper. Get a hacksaw and youre good to go!

4x4jeeptj Mine sounds good at low rpms. I unbolted my stock exhaust from the resonator and pulled everything out from under the jeep and cut the stock muffler out and welded in the new one and out it back on. The tailpipe still comes out at the back. Yall think if I cut that down to around the rear axle and put a turndown on that it will help a good bit. Im tryin to steer free of buying a header (even though I would love to) I dont have money for that right now. Another thing I considered was a magnaflow (or other brand) high flow cat or even a test pipe with an o2 defouler. Any suggestions on which would be best to do next? Thanks in advance

krisbman Another major factor is tail pipe, lotsa tail pipe= lotsa quiet. Ive got about an 18" tailpipe with turn down on my 40 series two chamber, Luv it!!!
03-06-2013 09:07 PM
krisbman Yep. Use a two chamber

barkern143 Put a new set of headers on it, that always makes all the difference

MorrisDC1986 wow great question, i remember when i replaced my muffler on my S-10 i ended up cutting out the cat and welding in a straight pipe. i got plently loud after that. lol. i have a co-worker that just removed his dual flowmaster 40 series mufflers and replaced them with magnaflow on his tacoma. i was going to ask a similar question but mine was more geared towards a custom dual. i was thinking about running a Y off the cat and routing a pipe over the rear drive shaft then 90* back and mount the second muffler around there somewhere. i have access to pipe bending and mounting equipment even fabricating and welding. what do you guys think? any obvious issues that i'm just to naive to realize?

FirehawkTJ If I go downtown in my town it's deep enough to set off car alarms down the street. Love that factor of it for sure!

Blacksurt I have a 40 on mine and really like it, you can hear it in the link in my sig....
03-06-2013 08:54 PM
Stevenkrans I live the throaty sound of mine...great topless and especially under bridges or in tunnels...I think it sets it apart!
03-06-2013 08:52 PM
FirehawkTJ I want to jump on this one because I've got a super 40 also. Interested to see what others have to say. One thing I did that made a very very small difference was change the intake. It breathes in better so it breathes out better also

Flowmaster 40 series

Just bought and installed a flowmaster 40 series muffler to replace my stock muffler. I didnt gut the cat or put a high flow on or anything like that. Amd its not as loud as I expected it to be. From the various youtube videos I watched I expected it to be loud and aggresive. Anyone had experience with these mufflers and how to get these best sound from them? And please refrain any negative comments about puttin a muffler on a jeep.
