just installed a magnaflow muffler
Yesterday i went to my local muffler shop and had a magnaflow muffler installed. I also had him remove the baffel/Cat that was basically just taking up space, i still have the ones attached to my exhaust manifold near o2 sensors.
The Muffler sounds good to a degree, kinda wishin i went with flowmaster. It sounds good until the transmission shifts and then the rpms lower but stay steady while jeeps cruisin. then the muffler has some low tone poppin, kinda reminds me of a bingo ball/lottery ball machine poppin the balls out, if i get into the gas it goes away, or if i get off the gas completly and just coast.. Not sure im going to stick with it, might swap to the flowmaster~

Thats normal for a magnaflow until it gets run in. Ive had a magnaflow put onto my last 2 cars, and it always started out with that ball popping noise. but it goes away, give it some time.

Thanks thats good to know, I guess i'll give it a chance and see, if it does that will be awesome, i do like the fact that its stainless inside and out and has a lifetime warranty, where flowmaster only has 2 yrs..

Its really hard to make a I6 or any 6 cyl. sound good, nothing beats a V8
