Threw on my new Magnaflow today (part #11259 / 4''x9''x18'' oval). The sound is exactly what I was looking for. Now my pickup actually sounds like a pickup should. I've never understood why the factory throws on such a massive muffler, but oh well, it's fixed now.

Tomorrow it gets new fog lights and Tuesday the front windows are getting tinted.

 

Do we get to hear it?

 

Sure can...as soon as I get a video of it

 

This is the same muffler I have on my 4.7l. I love the sound of it too, not too loud but sounds good when you get on it.

 

Nice! That's the exact muffler I put on my truck 5 months ago.
A definite improvement over the stock factory "trash can".
Did you keep the resonators on?
I opted (be it a few months later) to ditch the tail pipe and dump out in front of the right rear with duel chrome tips.
One less resonator = more sound. Looks and sounds really nice now.

 

I left the resonator on. I'm on the road a lot and I didn't wanna put up with any kind of annoying droan when the MDS kicks in.

I really happy with it. Now if I could figure out why my front Bilsteins are squeaking...I'd be set.

 

Do I need to pop a weep hole in the bottom of my new Magnaflow?

 

Considering its stainless.No I wouldn't Any moisture should be vaporized by the heat and expelled w/ the other exhaust gases.The reason they didn't put one in is the muffler can be installed in a variety of positions and is reversible with flow direction. Yours was center in offset out correct?
You got a good 10 year muffler.
Also I believe the 07 & 08 years only had one resonator...after the muffler. The 06's had two...One before and one after. I kept the one directly after the Y pipe and lost the tail pipe with that ugly resonator on it. No drone for me.

 

Yep...it's a center in - offset out. I'll leave it along.

I left the rear resonator on and I think it sounds perfect.

Thanks for the info.
