muffler choice for a 4.2L 258

I have to replace the muffler on the weekend warrior CJ7. What is a decent choice for a low price (no Stainless Steel as it will only get smashed) muffler that will make it sound a bit deepier without a tinny crappy sound?

I prefer a flowmaster my self. You can get one for around $40 or so. Try Summit, maybe a cheapy turbo muffler, I beleive they're pretty cheap.

Hey Spaz, how loud is your glaspack compared to a stock muffler? Is there a huge difference. Also, how hare was it to mount? More or less same dimesions as the stock?

I used the Dynomax Turbo. It sounds good at idle, accelration and fairly quite at cruise. But for some reason, at about 2000-2200 RPM's, it sounds borderline ricer.

I have a Magnaflow on mine which is pretty quiet but throaty under acceleration. According to the friend/muffler shop owner who is into Jeeps and fast cars, the Magnaflow had the good hp/torque ratings.

At idle, unless you bend down to hear it, it isn't much louder. Under acceleration it sounds pretty good, I think. Defintely louder at idle and under acceleration than the stock muffler. As for mounting it, I had Car X do it, I was buys w/ getting ready to move out to go to school. Mine was about 26 inces long, so the fit was much different.
