Mufflers, I'm at it again!
For those of you who know me and how many mufflers I had on my 00 Silverado, I thought I would share this. I've gone through four mufflers on my Hemi Ram and decided enough was enough, I went back to stock. The stock muffler actually has a decent sound to it and is the only muffler that doesn't resonate in the cab even with me using the stock 3" tailpipe and factory resonator. My truck is dead stock now except for the ram-air system I made for it, no tune, no intake and now no muffler.
When I decided to go back to stock I was wondering how much performance I would actually give up so I did several G-tech runs when I still had the Magnaflow 12589 muffler on my Hemi Ram. Since putting the stock muffler back on, I've done several more G-tech runs and compared the results. I got in five runs with the Magnaflow and have done seven with the stock muffler on. I did 0-60 and 1/4 times, mph and even recorded the temp each evening. I averaged out the numbers and here's what I got.
Magnaflow: 0-60 in 7.09, 1/4 in 15.45 @ 91.0 mph, ave temp 53*
Stock: 0-60 in 7.18, 1/4 in 15.51 @ 90.5, ave temp 55*
So, you can see that the Magnaflow did make a difference but not really that much. I'll give up the small power gain (butt meter couldn't tell the difference) of .09 0-60 and .06 1/4 mile not to have the muffler resonation inside the truck. Now, alot of people think the Magnaflow is one of the best mufflers to swap out if you want to use the stock tailpipe (for the Hemi Ram's), this shows me it changes the noise level more than it changes performance. I just bought an Airaid Jr. intake kit (MIT tube and drop in filter), that be be my next G-tech test. Just thought I would share this!

Yeah I used to be all about loud, now it just anoys the **** out of me. Especially on trucks, all it is is making them loud, in most cases they arent fast (except obviously for the people posting in here ) Now a choppy big block chevy, or something running 10s, that sounds great to me.
