06gpgxp

Good afternoon all,
I have a '06 gxp with 55k miles on it and stock exhaust. Unfourtantly the driver's side muffler is rotted out and feels spongy. I would like to replace it with the magnaflow cat back system and was wondering whats the difference of exhaust tone in the interior between stock and the magnaflow? My wife drives it about as much as me and it's getting really loud in the interior for her liking. Any comments would be very much appreciated.
Thanks!

Magnaflow definitely adds a deeper tone to the exhaust note when comparing it to stock exhaust. There's virtually no drone and it doesn't really get louder til you get on the gas. If you're worried about sound why don't you just pick up the mufflers instead of the whole cat back setup? Saves you some money and doesn't add a lot of unwanted noise.

Mine drones a good amount between 2-3k rpm, but its also 4 years old and seems to have gotten louder with age. Maybe it drones more on the GXP? On the durability front though, it has minimal rust, tips are still perfect.

If the rest of the system is fine, you could just replace the mufflers

Mine droned a lot too and I had a bad reaction with DOD.

A lot of vids on you tube, I just removed my muffler's and IMO have the perfect sounding exhaust. Lots of drone but thats ok, i turn the radio off and just listen to her sing!

Thanks for all the comments it really helps! I've listened to a few youtube videos and really like the magnaflow exhaust note. I noticed a few of you noted the drone being worse than stock and would like to tune out dod to resolve the helicopter and drone. I really would like the interior sound to be no more than stock since I have a 2 year old and a 3 week old riding in the back.
Thanks again everyone!

I would just go with stock mufflers then, pretty much any after market exhaust will have some 'noise' side affect that you may not like. On my 08 GXP I have the stock mufflers with the resonator removed, in my opinion its the perfect exhaust sound on a daily driver.

It sounds good when idling and accelerating, but on the highway is has no more drone that when it was new. I have heard a few magnaflow & flowmaster cars in person, they sound good but all of them had cruising drone at highway speeds. Taking DOD off will help the helicopter noise but the overall drone will still be there.

So from what you wrote, I would say definately stay with stock mufflers. But who knows maybe a loud exhaust would put those kids to sleep.

the magnaflow kit is a real nice system, and is worth a few extra hp.
i paid 550 shipped for mine.

considereing how mellow and quite the magnaflow system is outside the car it sure sounds loud as hell in the inside.

I love my Magnaflow. If you like a quiet ride it may annoy you but it is not very loud at all.
