going to be removing stock muffler, looking for a high flow one thats fairly quiet at idle but sounds good when floored. don't care if it doesn't bolt right up, exhaust shops are cheep

 

look into MBRPs kit you can get a skid plate for the new muffler and they are a canadian company

 

i like the mbrp's but its a bolt up system, good cause i could do it but i want the pipe to exit the side so instead of chopping the mbrp i was thinking of getting a strong steel muffler and get a shop to put in on

 

i got the gibson dual and love it

 

so is the bottom end thing a myth. i guess only the dyno would tell, from what i hear its all "butt-meters"

 

I was going to ask this same question. I did some damage to mine on its first outing. Does anyone have the Flowmaster 44 on their JK?

 

I just had this Flowmaster installed on Thursday. It is a series 40, they used as much of the factory pipe as they could. When they removed the factory muffler, they just added a piece and now it exits on the left rear.

It has a good throaty sound at idle and has a little rumble when you take off. It reminds me of the 4.0 that the older wranglers had. Total price was $110.00 including installation.

I included a couple of photos and a movie clip, sorry but it was kind of windy.

I second the flow master Have had mine in the stock location and now in front of the axle. Less resinance in front of the axle but i really like the sound at idle in either position.

 

yea flowmaster 40 installed like 4 months ago and i smile every time i start it!!! go for it!

 

Dynomax is pretty good....

Nice sound, like you said pretty quiet at idle but nice rumble when you floor it...

I got it , I love it...

just my 2cents
