sounds good! you are selling me on putting a glass pack on my truck. i assume that themuffler inlet and outletis the same on your 4.7 as it is on my 5.2, what was the make and part number of yours if you can remember? i saw Thrush glass packs at my local parts store for 20 or 25 bucks i think. way less than the 80 bucks or sofor a flowmaster or a magnaflow turbo muffler and even if it doesnt last as long i can replace it 3 times over for as much as ill spend on one of those. its got to last at least 5 years and i doubt a pricey muffler would last even close to 15 years...

 

Yeah, im not sure what the part number was but I just bought the Thrush glass pack from the auto store. I just measured the exhaust pipe first to make sure it would fit.

 

i have a 20" glasspack on my 4.7L and it cackles like no other!!!! i also put on a CAI that i made from different parts at autozone ill upload a couple of pic lata

 

The glasspack, cherry bomb single inlet / dual out sounds really awesome. My friend has this.

 

Yeah the one at advance auto I was looking at was a thrush glass pack.
