time for a muffler upgrade...

OK so I am looking at the Flowmaster 40. Seem to be a popular one on the JK and Jeeps in general.

What size are you guys going with? Anyone regret buying it? Where is the best place to buy one?

I have a tubular MagnaFlo.

It gets old at highway speeds in my 2.5L TJ. 3000+ RPMs constantly means it resonates pretty much all the time. There's some vids I think in my photobucket account by this screen name.

All you are going to get is a different pitch sound. No performance increase whatsoever. I regret "upgrading" my exhaust.

Keep the stock pipes and muffler and save your money for other things like Gas. A new muffler will do nothing for you other than relieving you wallet of your hard earned cash.

That's not true! There is a good chance a new muffler will annoy the **** out of everyone around, due to the increased noise it will probably make.

If I had paid for mine when I got it. I wouldn't have paid for it.

Not worth it I still frequently put the stock back on, from time to time.

thanks for all the feedback guys.

I ripped the stock one off and stuffed a super 44 under it inline. Just made a cut of about 18" or so and clamped it in. Had the kid tack it in a couple spots so it wouldn't move around and added a heat shield so the rear passengers wouldn't melt their shoes. Cost me under 100 for the whole deal and has a nice little rumble, as much as the 3.8 will let it.
